Basics of Geo-Mechanics and Hydrology Dewatering of Open Cast Mines Well-systems

by Univ.-Prof. Dr.-Ing. habil. H. Tudeshki Surface Mining and International Mining | TU Clausthal | Germany

As mentioned in the previous chapter, so-called wells are drilled into the underground and completed, so that ground water can be lifted (extracted). In principle, well-systems are differentiated according to the following main criteria: 1. Fully well 2. Partially penetrating well

Well systems For a full description of well systems, it is important to describe two terms: Partially and fully penetrating well. A fully penetrating well reaches an impermeable layer, and the ground water only flows into the well through the mantle, not through the bottom. The filter pipes extend over the entire thickness of the aquiferous layer. This is not the case in a partially penetrating well. Here the filter pipes do not reach to an impermeable layer, but end in a layer that conducts water (so-called aquifer) (Fig. 1). Thus, water flows in through both the mantle and the bottom of the filter pipe. The following calculations for well systems determining the water encroachment/amount of water influx- apply only to fully penetrating wells. For the time being, there is no direct mathematical solution for partially penetrating wells. Therefore calculation is initially done, as if a water-influx through the bottom of filter pipes is not possible. Subsequently the amount of inflowing water through the well bottom is consideration and added.

partially penetrating well


EDUCATION Calculation and dimensioning of wellsystems The following parameters are decisive factors in calculation and dimensioning of wells: • H: Depth of the aquifer in m; distance between the ground water level and the underlying impermeable layer • s: Lowering depth in m • h: Distance between water level in well and the underlying impermeable layer • R: Lowering range in m; corresponds to the distance between the center of the well and the location, where the drawdown curve reaches the original ground water level. • r: Radius of well in m

In order to calculate wells, it is assumed that the well extent in depth reaches an impermeable layer. In cases where this assumption is not applicable, the inflowing water from the well bottom is added, based on the distance between the well bottom and the impermeable layer. The course of the drawdown curve is calculated according to the following formula:


Water flowing into the well qA [m3/s] is also called encroachment. The value k corresponds to the coefficient of permeability of soil in m/s. The range R is calculated from the empirical equation of Sichardt, as follows:

R = 3000·s·√(k·[m]) The capacity of a well is also empirically calculated as follows:

qF = 2 ⋅ π ⋅ r ⋅ h ⋅

k 15

Accordingly, correct capacity or dimensioning is only possible, if the encroachment corresponds to the capacity of the well. In order to determine the permeability of rocks in situ, pumping tests are carried out. Based on calculation formulas for encroachment, the average permeability of subsoil can be determined, as follows:


q A ⋅ (ln R − ln r ) π H 2 − h2



m in   s


π ⋅ k ⋅ H 2 − h 2  m³  .  qA = ln R − ln r  s  Fig. 2: Determination of range of drawdown

Issue 03 | 2012


EDUCATION In case several measuring points are set up, the following is generally applicable:



q A ⋅ ln y 22 − y12 ln x 2 − ln x1


m in   s

Hereby, values x1 und x2 represent the distance of measuring points to the center of the well. The values y1 und y2 represent water-levels in corresponding measuring points, measured from the bottom of the impermeable layer. In case the calculation is done for a well in confined ground water– which is often the case in a horizontal well – the following formula is applied:

qr =

π ⋅ k ⋅ 2 ⋅ m(H − h ) ln R − ln r

Hereby m equates to the thickness of the confined, permeable layer. Dewatering of surface mines is only possible through construction of a multitude of wells. For the sake of calculations the mining field is assumed a circular well, into which water flows from all sides. The theoretical equivalent radius E of a „Mehrbrunnenanlage“ is gathered from the surrounding area of individual wells and is calculated by approximation from:


with: η = 0,2 ⋅

a + 0,37 b

Hereby a is the longitudinal side and b is the width of the mining field. In case fields are formed differently they are approximatively assumed to be squares. The total amount of water to be lifted is:

QA =

π ⋅ k ⋅ (H ² − h ²) ln R − ln E

The amount h is equivalent to the lowest water level at the bottom. The amount QA of water is calculated as follows:

QA = π ⋅ k ⋅ (H ² − h ²) ⋅ (2

E + 0,25) R

Groundwater Cuttoff In order to limit the range of a drawdown and protect sensitive landscapes, the ground water inflow can be prevented with hydraulic barriers along the surface mine edge, This allows for maintaining groundwater outside of the surface mine. In order to do so, artificial components are inserted into the surrounding medium. Pile walls and cutoff walls fall into this category . As example, the construction of cutoff walls can be done with special keyway cutters, as shown in figure 4. The trenches are filled subsequently.

A water influx can also be stopped through sealing of pore spaces in soil by injection or ground freezing in a narrow laminar section in situ. Costs and limitations of this method are • For pile walls at 25 m and approx. 140 € / m² and • For slurry trench walls at 100 m and approx. 100 - 170 € / m². [2]

“Commodity Marketplace” The New Service on AMS Online ! The Global Importance of Commodity Trade

Globally, commodities play a crucial role in industrial production, as they have a significant share in economic development of individual countries, and contribute to industrial booms. Since the internationalization of mining and global commodity trade, commodity markets have continuously grown. The growing consumption of raw material increases concerns on secure and sustainable commodity supplies of industrial nations and in the global economy. In future, the challenge will be a long-term guarantee for the increasing need for commodities, in order to avoid supply shortfalls and distortion of competition. From the geological point of view, future supply of mineral commodities is ensured. But in terms of planning reliability of enterprises, it is jeopardized by numerous delivery risks. Nevertheless it is expected that commodity trade will gain increasing importance in the future.

The Idea of AMS-Online “CMP”

We are planning to use our proximity to raw material production, as well as our strong network with the global commodity industry as a basis for our contribution to the global commodity supply. Raw material has a big share of the global commodities trade. The growing demand will lead to the fact that global trade will increasingly take the form of organized market structures. The mining and extraction, as well as the processing of raw material is often done in different countries. This is the reason why we have decided to create the platform called “commodity marketplace”, which will provide a forum for an exchange of supply and demand of raw material.

Energy and Raw Material for Tomorrow Results of IHK- Enterprise- Barometer 2012

Deutscher Industrie- und Handelskammertag e. V. (DIHK) Berlin 2012 | Ger,many

Summary of Main Results • Enterprises are facing great challenges with regard to energy and raw material supply. Main problems are increasing prices and security of supply. For 86 per cent of enterprises the increasing energy prices are more important than before. Therefore, 64 per cent of enterprises advocate for a reduction of governmental taxes on electricity tariffs. The mix of instruments, i.e the mix of CO2- emission trade, renewable energy laws and energy taxes lead to an unnecessary increase in energy prices. Therefore the DIHK requests for a better coordination of these instruments, thus limiting the burden of enterprises. • 58 per cent fear blackouts. Although blackouts are less likely to happen than price increases, its effects are disproportionally grave: Blackouts can paralyse production processes, destroy plants and make Germany less attractive as a business location. • Germany has taken a different path in Europe with its accelerated energy turnaround. However, the majority of enterprises (76 per cent) request that German energy policy is better integrated into the European context, and in particular that cross-border electricity trade in the EU is further developed. • In order to maintain security and stability of energy supply in Germany, the DIHK and German enterprises expect more engagement from politics. The task of politics is to strengthen public acceptance for expansion of electric supply networks (92 per cent). Enterprises believe that this is a central prerequisite for the success of the energy turnaround. In this regard the IHKs are willing to bring in their expertise. • Increasing prices of raw material are a problem for 76 per cent of enterprises, particularly for industrial enterprises (93 per cent). A sufficient supply of raw material is also increasingly questioned (47 per cent). • Therefore, the Federal State and the EU should advocate for a free access to raw material; as an example raw material partnerships can be established as accompanying measures to the efforts of enterprises. However, the enterprises are very critical of the idea of introducing a Europe-wide raw material tax: Only a small minority of 17 per cent of enterprises believes this is a reasonable political measure. • In order to respond to challenges, many enterprises focus on efficiency measures: Three quarters have already taken or are planning measures to increase energy efficiency. Over half of the enterprises focus on a more efficient application of raw material. • The DIHK and enterprises expect general frameworks, that are reliable. They do not want rigid specifications, but would like to act on their own responsibility. A majority (85 per cent) requests for an improvement of general frameworks for new technologies. • In industry, every fifth enterprise claims that it has transferred capacities or that it is planning to do so. Germany as an industrial location is considerably loosing quality in terms of energy and raw material supply.

Increasing Challenges in Energy and Raw Material Supply Enterprises are facing ever increasing challenges in energy and raw material supply. At the center of these challenges are increases and fluctuations of prices. In addition, sufficient and secure supply of energy and raw material is also not taken as granted any more.

Issue 03 | 2012

Increasing Prices: Risks for the Economy Following the nuclear accident in Japanese Fukushima, German politics decided to stop generating electricity from nuclear energy by 2022.Eight nuclear plants were decommissioned with immediate effect, and the remaining ones will gradually drop out of generation of electricity. It is planned to generate 80 per cent of electricity and 60 per cent of energy from renewable sources by 2050. Development


TRANSFER OF TECHNOLOGY Fig. 1: Chart 1 [Source: IHKEnterprise- Barometer 2012]

of renewable energies, modernization of electric supply networks, creation of energy storage, as well as the renewal of generation systems- they all have to be financed with increased electricity bills for enterprises and users. It is therefore obvious that 86 per cent of German enterprises believe that increasing prices have more effect on their future business than before. 93 per cent of enterprises in the industry, and even 99 per cent of enterprises in the construction industry expect more impact of increasing energy prices. Another pivotal challenge for the economy are the increasing fluctuations of energy prices: The liberalization of energy markets allows for unrestricted agreements on prices between producers and industrial consumers. For a long time this has been the case for oil and fuel, and the same applies for gas. The Leipzig Electricity stock exchange shows reference rates for longer term, as well as short term electricity supply, which is based on supply and demand. Thus in 2011, the daily average price, weighted by hour (Phelix Day Peak), fluctuated between 8 and almost 80 Euro per MWh. The decisive factor for these price ranges is renewable energy, which in 2011 has been supplying almost 20 per cent of electricity: If in case of solar radiation and strong wind the supply of electricity increases, prices fall, in the case of weak wind and lack of solar radiation, prices increase. With the development of renewable energy, price fluctuations become normal.

has an increasing impact on their businesses. The industry (66 per cent) and construction industry (74) are again disproportionately affected.

Enterprises Fear Power Failures The consequence of the immediate shut down of eight nuclear plants was a decrease in secured output. The Federal Network Agency has announced that the risk of a power failure over a wide area has increased. Therefore enterprises attach high importance to this issue, similar to the importance of price fluctuations: Overall, 58 per cent of enterprises , and in particular 65 per cent of industrial enterprises believe that power failures and voltage fluctuations have higher relevancy to their business than before. This shows that in Germany security of energy

This poses both risk and opportunity, and therefore 56 per cent of enterprises believe it

Fig. 2: Chart 2 [Source: IHKEnterprise- Barometer 2012]

Issue 03 | 2012



Fig. 3: Chart 3 [Source: IHKEnterprise- Barometer 2012]

supply is not at all taken for granted, but more and more it threatens to become a risk of the business. Security of supply is also an increasingly important issue for 59 per cent of service enterprises. As an example, ITservices are directly dependant on a secure power supply. Such a high security of supply has been and still is a pivotal advantage of location for Germany: While in Germany the average power interruption per year has been 16 minutes, this figure is 200 minutes in the US. Up to now enterprises had judged the secure energy supply as an advantage of the industrial country Germany, but they voiced their concern on a reliable supply already during the course of 2011.1 (cf. DIHK-survey on industrial location Germany, August 2011) Enterprises are more concerned about electricity prices than about blackouts and voltage fluctuations. The difference is 18 per cent. This is understandable, as increases in prices affect every enterprise, but smaller voltage fluctuations do not interfere with the daily business of many service providers. However, the consequences of blackouts are more grave than increases in electricity prices:

Blackouts are not only inconvenient, but can bring production processes to a standstill, destroy plants and make the Germany less attractive as an industrial location. The cut off of the eight nuclear plants has led to the fact that the number of interventions of system operators has more than doubled. Nuclear plants have to be connected and disconnected in quick succession, in order to ensure stability of the network. This calls for immediate action.

Regulations Hinder Enterprises In order to shape the energy markets of the future, the state has to create frameworks for energy from renewable sources. The state has to ensure that sufficient electricity is continuously fed into networks. The operators of transmission and distribution networks have to be encouraged to invest. This includes, for example, acceleration of licensing procedures. At the same time, lawmakers begin to work towards a decrease in demand for energy: The European Commission has suggested that energy suppliers ensure to reduce the energy consumption of their costumers by 1.5 per cent annually.

Fig. 4: Chart 4 [Source: IHKEnterprise- Barometer 2012]

Issue 03 | 2012


TRANSFER OF TECHNOLOGY In addition, the Federal Government is planning to oblige enterprises, which are partly exempted from paying ecotax, to save energy through energy management system, in order to maintain their competitiveness. 47 per cent of enterprises believe the increasing regulation of use of energy is a challenge. Here again the number of industrial enterprises is higher than in other economic sectors (59 per cent), as they are more affected by these measures. Rather than interfere with regulations, it would be more reasonable to overcome information barriers and assist enterprises to increase their efficiency.

Secure and Affordable Raw Material Supply – Top Issue for the German Economy Enterprises are increasingly emphasizing the importance of a secure raw material supply. This significantly increased awareness of the problem is triggered by the massively rising prices for industrial metals and soft commodities. The shortage of noble earths has alerted many industrial enterprises of placing more emphasis on raw material management. In 2012, already 58 per cent of enterprises believed that rising prices for raw material present a problem for their business (“Raw material dilemma begins to show”, DIHK- Analysis of enterprise barometer, November 2012); However, currently, already 76 per cent of enterprises believe that the rise in prices of raw material is a challenge. The same applies to the issue of access to raw material, which enterprises analyse more critically by now. In 2011 almost half of them believed that access is jeopardized, which shows an increase of almost double since 2010 (2010: 26 per cent, 2011:47 per cent). When we observed last year that “the raw material dilemma begins to show”, we have to realize now, that “the raw material dilemma is here”.

Calculation of Price Trends More Difficult The challenge for most enterprises is a combination of rising prices on one hand, and prices that are difficult to calculate on the other hand: 76 per cent mention rising prices of raw material as a problem. Even the percentage of industrial enterprises, out of which 91 per cent were alarmed already in 2010, rose to 93 per cent. Significant increases in prices, as compared to 2010, were seen especially with imported raw material. Enterprises believe that this trend will continue in the long term – reasons for this are mainly the global increase in population and the strong economic growth in threshold countries. Increasing raw material prices lead to higher production costs, which cannot easily be transferred to market prices, due to the noticeably reduced demand. The German experience shows that increases in prices, particularly in food production industry, are not accepted by the priceconscious German customer. Taking into consideration the fierce competition in world markets, shifting of prices is also difficult for German industrial enterprises. The answers of representatives from the construction industry indicate that prices of domestic raw material are on the rise: 100 per cent mention price increases as the problem. The construction industry obtains a considerable amount of mineral commodities, like sand and gravel, which are mined in surrounding regions. These mineral commodities are increasing in price, as the respective mining areas are not sufficiently developed. More than fluctuations in energy supply, it is the fluctuations in prices of raw material that are a problem for 59 per cent of enterprises. Although hedging can provide some space, in case of higher volatility of prices, they become more expensive. Since the industry is particularly dependant on imported industrial

Issue 03 | 2012


TRANSFER OF TECHNOLOGY commodities, they are fully affected by the imbalances of global raw material markets. Three quarters of the industrial enterprises (76 per cent) see a risk in this fact. The construction industry also assesses the fluctuations in prices as critical (81 per cent); they make purchase of raw material more difficult, because in case of decline in prices a stock which has been bought expensively will burden competitiveness.

announced that it will limit its export of noble earths to 10,546 tons in the first half of 2012 – while having a global market share of 97 per cent and a global demand of 120,000 tons. This is a decrease of 27 per cent, compared to the previous year. Therefore in the coming years fluctuations in prices will also characterize raw material markets.

Fluctuations in prices also have an immediate influence on profitability of opening up new raw material deposits. This applies to mine projects for mining of noble earths in Brazil, the US and Australia, for example. China has

Access, Quality and Regulation is Becoming a Problem with Regard to Raw Material

It is alarming, but not surprising, considering such news: Almost half of the enterprises (47 per cent) and more than two thirds of industrial enterprises (68 per cent) even see risks in access to raw material. In 2010 the share was 26 per cent , and 58 per cent of industrial enterprises saw a problem in access to raw material. In case of imported raw material this reflects the observation that export of raw material is increasingly running short from the strategic point of view. Prices are increased because of such shortages, barriers to trade and agreements. At the same time domestic demand is increasing in threshold countries like China, which previously were exporting large quantities of raw material.

Furthermore the climate change is accompanied by the risk of crop failures, which in turn reduce the raw material supply for food production. The quality of raw material is also becoming a problem for the economy: 42 per cent of all enterprises and 58 per cent of industrial enterprises expect more difficulties in the future. This is a hard blow for the German industry, since it is highly specialized and does not only need many commodities, but also commodities of high quality and purity. For production of modern technologies like microchips, solar cells or technical ceramic products there is a need for very pure material. Half of the enterprises (49 per cent) fear an increasing regulation of raw material consumption in the future. These numbers are significantly higher in industry, construction and trade. The efficiency of application of raw material and material is supposed to be subjected to new regulations through broadening of product-related directives. The EU is discussing a strategy to increase resource efficiency

and is suggesting higher taxation. German politics is considering a resource efficiency program (ProgRess), which can also lead to new regulations for products and production.

Economy is Acting! Since supply of energy and raw material at economical prices is often not secured any more, many enterprises embark on new paths. The spectrum ranges from changes of delivery conditions to increasing efficiency and transferring activities to outside the country.

Higher Efficiency, New Suppliers, More Proactive Action The increase in energy efficiency is very popular among German enterprises: 75 per cent of all enterprises pursue the strategy of achieving more with less energy. This is daily routine for almost half of them (47 per cent), 28 per cent are on the verge of implementation of planned efficiency measures. The forefront runner is the

industry: 88 per cent of all industrial enterprises aim at a more efficient application of energy. For over two thirds (64 per cent) this is already business as usual, almost one fourth (24 per cent) is planning to tackle this issue. The share of enterprises that want to increase energy efficiency is also above average (88 per cent) in the construction industry. It is noteworthy that in this sector there is a high share of “newcomers� in energy efficiency of 40 per cent. Commercial enterprises are also very active in energy efficiency measures, as over two thirds of them (69 per cent) are on board; 35 per cent have already taken measures and 34 per cent are planning to do so. For enterprises in the service sector the improvement of energy efficiency is also the most important measure: 43 per cent of service providers have already taken measures for a more efficient application of energy, 27 per cent are planning such measures.

Issue 03 | 2012

In order to secure energy supply and be able to calculate with steady prices, many enterprises look for new suppliers (41 per cent), or plan to look for them (22 per cent). From April 2012 onwards, a change to a new supplier will take a maximum of three weeks, whereas up to now it takes at least a month. From that date onwards the supply can start any day and there is no need to wait for the beginning of each month. In many cases the industry has intensified the search for new suppliers (60%), a further 17 per cent are in the starting blocks. It is a bit surprising that the issue of change of supplier is also relevant for the majority in the construction industry, trade and in the service sector. This shows that in this regard, almost 14 years after liberalization of electricity and gas markets, competition in the retail market is functioning.


TRANSFER OF TECHNOLOGY Fig. 12: Chart 12 [Source: IHKEnterprise- Barometer 2012]

This changing mood does not mean that enterprises do not appreciate steady supply relationships: Two thirds of enterprises believe long-term supply agreements are desirable. This particularly applies to the industry, where 70 percent have long-term relationships, and 14 per cent are aiming at such relationships. There is less such willingness for contractually binding obligations in the trade sector, while in the service sector there is more inclination to short-term supplies, due to lower energy needs. As expected, there is a lower tendency to long-term supply agreements in smaller enterprises. Since they have less power of demand, they usually are not in a position to negotiate better conditions and they see their flexibility as an advantage. Another instrument for steadier prices regarding energy supply is safeguarding through forward contracts. Every fifth enterprise is either using this modality or is planning to do so in the future. In industrial enterprises, which are highly affected by fluctuating energy prices, one fourth of them protect themselves with the help of forward contracts; a further ten per cent are planning to revert to hedging in the future. Against this background, the new measures planned by politics to regulate finance markets through exceptions should ensure that safeguarding through forward contracts should remain possible and feasible in energy trade.

to create own supply capacities up to now, and an even higher portion (21 per cent) are planning to do so. Previously, an own energy supply was mainly an issue for bigger industrial enterprises; however, it is becoming increasingly interesting to the small firm sector. After all, 10 per cent of enterprises with up to 10 staff have placed this on their agenda (5 per cent have already implemented it). The use of geo-thermal energy, solar heat or power-heat cogeneration is becoming increasingly popular and is also feasible for smaller enterprises. Across all sectors, more enterprises have planned the setup of their own energy supply. Less have actually implemented it. Even among service providers, traders and constructors, 15 per cent are intending to implement their own energy production. This shows that even for unrelated industries, some forms of own energy production – taking into consideration EEGfunding- are economically interesting. The high share of planned measures also reflects increased environmental

More and more enterprises build on setting up their own energy supply capacities. This particularly applies to industrial enterprises, out of which 16 per cent have taken measures

TRANSFER OF TECHNOLOGY awareness, as well the worries of enterprises about a steady and sufficient supply of energy. Many enterprises are challenged by the accelerated pullout from nuclear energy and the network infrastructure, which was not designed for a decentralized energy production. In particular industrial enterprises fear blackouts and voltage fluctuations, and they therefore focus on building up their own capacities. In addition to the above-mentioned measures, more and more enterprises focus on activities in the areas of research and development (R&D). They are aiming at saving and more efficiently using energy through new technologies, products and processes. One fourth of enterprises (23 per cent) have already started or are planning to strengthen their R&D. The driver for this is the industry, where 53 per cent of enterprises take care of R&D measures, 34 per cent have already taken steps and 19 per cent are planning to do so. Here again it is evident that the economy is applying creative strategies to proactively respond to the challenge of the energy turnaround. Among these is, for example, the development of new business models, particularly in the area of energy services. The enterprises want to increase their competitiveness with more intensive R&D activities, while at the same time contributing to the protection of resources.

Competition for Raw Material: Diversification and Management of Resources as a Response Many commodities are subject to increasing supply shortages, and prices are highly rising. One of the reasons is the greatly growing demand, resulting from the global population increase and the economic growth of threshold countries, in particular. Increasing capacities for extraction of raw material requires time and calls for considerable investment. Another reason is that some export countries are artificially lowering their supply on the global market. Commodities like noble earths, which have drastically increased in price, are needed for important “green technologies� like wind turbines, photovoltaics and LEDs. Therefore an increasing number of enterprises have to make more efforts to secure raw material supply. However, it should be noted that sectors are affected to various degrees: The construction and industrial sector are particularly affected from the scarcity of raw material, whereas trade and service enterprises are indirectly affected. Compared to the DIHK enterprise barometer 2010, enterprises are becoming even more aware of the issue of scarce resources, and are taking further measures to protect their resources. If raw material supply becomes uncertain, obviously the procurement strategy needs to be changed. Thus the share of enterprises in all sectors, which make efforts to find new suppliers (54 per cent) or seek for long-term supply agreements (47 per cent) is high. 18 per cent of enterprises also seek to protect themselves from high price risks through forward contracts. However, since the scarcity of raw material is not a passing phenomenon, enterprises also try to reduce the usage of raw material. Half of all enterprises (51 per cent) attempt a more efficient usage of raw material. Substituting scare raw material (31 per cent), as well as engaging in research and development (25 per cent) is also gaining importance. The results clearly prove that the industry, in particular is facing great challenges with regard to raw material supply. Therefore the responses of industrial enterprises are further elaborated in the following:

Issue 03 | 2012


TRANSFER OF TECHNOLOGY While searching for raw material at acceptable prices and with adequate quality, the industry relies mostly on a multitude of suppliers. Three thirds (78 per cent) are already looking for new suppliers, another 9 per cent are planning to do so. At the same time almost all enterprises in the processing trade (82 per cent) are trying to protect themselves with long-term supply contracts, a goal that is increasingly difficult to achieve in an unsecure market environment. Therefore there is also discussion on measures of backward integration: Enterprises are trying to integrate upstream production steps, up to raw material extraction. Examples are purchasing cooperatives, which are also an option for smaller enterprises. Resource management is also becoming more important for industrial enterprises. The most economical raw material is the one which does not have to be purchased. Experience shows that, particularly in KMU there is still a significant potential. 79 per cent of industrial enterprises focus on a more efficient usage of raw material- a value that is higher than the average of all sectors (52 per cent). Substituting raw material also plays a part: One third of industrial enterprises (35 per cent) are already taking such measures, more than a fourth (26 per cent) are planning for substitutions. The comparatively high share of industrial enterprises that are planning this measure proves that although substituting raw material has been acknowledged as an option by many enterprises, the actual implementation of this measure can often only be done with high costs in the production process. Substitution is also limited by the fact that many substitute raw materials are becoming scarce. In this regard there is a need for intensive research and development to fully tap the potential of resource management. 45 per cent of industrial enterprises are already engaged in research projects, 20 per cent are planning to engage. Thus already two thirds of industrial enterprises are actively engaged in R&D, proving the high innovation of the German industry, which uses R&D as a key to remaining in the global competition of raw material. The goal is to produce, while being gentle to resources.

The Industrial Location Germany Under Pressure Although there is a clearly increased concern for secure and economical energy and raw material supply, enterprises mostly remain loyal to Germany. However, with regard to energy, seven per cent and with regard to raw material, eight percent of enterprises state that they either

Issue 03 | 2012

are shifting or planning to shift capacities abroad. This is quite remarkable, considering taht overall, Germany as a location enjoys relatively good capacity to compete. This share is double (15 – 18 per cent) in the industry and shows that the location Germany is considerably loosing quality in terms of energy and raw material supply. Altogether a smaller number of industrial enterprises invest outside of the country, for financial reasons– which is a sign for competitiveness of the production location Germany. (Compare with DIHK survey on foreign investments of the industry 2011). However, for reasons of insecure raw material supply, already one out of ten industrial enterprises has shifted production to outside the country and another 8 per cent are planning to do so. The shares are only slightly lower when it comes to energy supply (nine and six per cent respectively). All this points to the fact that the framework conditions for industrial production in Germany is being jeopardized, particularly with regard to the location factor “energy and raw material supply”. The availability of raw material and energy supply are crucial competitive factors, which apparently are found at lower costs outside of Germany. Vice versa, this will also impact the decision of foreign enterprises to settle down and invest in Germany.

German Economy is Requesting for Reliable Conditions Although enterprises are facing the new challenges in energy and raw material supply, they also need the support of politics. Enterprises need reliable conditions with adequate leeway for innovation and for being proactive! In the ranking of the requested political measures (average scores, scale of 1 to 5), and against the background of energy turnaround, acceptance of network development (score 1.4), better conditions for new technologies (score 1.7), as well as strengthening of technology-oriented energy and raw material research (score 1.7) are taking the lead. The economy also sees politics responsible for issues such as incorporation into the European context (score 1.9) and in international raw material trade (score 2.2). Instruments that push prices, such as charges (score 2.1 for reduction) and new taxes (score 3.7 for their introduction), as well as other interventions in corporate policies (score 3.1 for binding efficiency regulations) are unwelcome. “Energy and Raw Material for Tomorrow”: Challenges are great, there is plenty to do!


TRANSFER OF TECHNOLOGY Fig. 15: Chart 15 [Source: IHKEnterprise- Barometer 2012]

Mastering the Energy Turnaround: Higher Acceptance, More Europe, Less Charges on Electricity Tariffs Politics should not overburden the economy with the consequences of the energy turnaround, but should establish the right conditions for its successful implementation. The German economy believes that strengthening public acceptance for the needed expansion of the network is on top of the agenda: 92 per cent of enterprises believe such a measure would be meaningful. Entrepreneurs are aware of the fact that the energy turnaround can only be tackled with a massive expansion of the network infrastructure. There is a need to direct wind from off-shore wind plants in the North Sea to industrial areas with high population density. Power fluctuations of renewable energies have to be balanced and many decentralized power generating units have to be integrated into the network structure. This is a huge task, and the economy believes that it has not been addressed with the needed consistency. The experience in many big and small infrastructural projects – from wind engines to highwaysas well as with Stuttgart 21, shows that acceptance of the population is an essential prerequisite.

The entrepreneurs believe that, in order to secure electricity supply, a single European market should be established. Power peaks and demand peaks can only be balanced with cross-border activities. 76 per cent of enterprises believe it is meaningful to expand the crossborder power trading. At 80 per cent this demand is even stronger in the industry and construction sector. Following its solo attempt in the energy turnaround, this is a clear call for the Federal Government to further integrate its energy policy into the European context and to support the single European market. There is a lot to be done in this regard, as there are still legal and physical barriers to a fully integrated European power and gas market. Thus, the Federal Government should pursue development of cross-border infrastructures and the existing consistent implementation of legislation in all member states.

Fig. 17: Chart 17 [Source: IHKEnterprise- Barometer 2012]

Within the framework of the energy turnaround there have been repeated discussions on new subsidies for, e.g. Nuclear plants and capacity markets. Financial aids, however, increase the already high public charges on electricity tariffs, which create big problems for the economy. The renewable energy allocations, the promotion of combined heat and power generation, electricity taxes and license fees burden enterprises: therefore 64 per cent of all enterprises believe that it is meaningful to reduce public charges. Such charges should be reduced to a minimum and flexibly include new developments, e.g. promoting renewable energies. As subsidies do not correspond to the model of balancing the demand and supply on the electricity market, the vast majority in the economy disapproves of such a measure. In its position paper on energy policy of November 2011, the DIHK has stated a corresponding opinion (Decision of the DIHKmanagement of 17. November 2011 with regard to the demands of the economy from a future energy policy,

Secure Access to Raw Material at Economical Prices In the area of raw material supply, enterprises particularly see the need for action of the state with regard to free access to raw material: 63 per cent of enterprises believe this is a task of politics. Underlying this demand is the fear that countries with rich deposits set up export barriers, in order to create advantage for their products in the global market. The Federal Government and the EU Commission are requested to advocate for a free and fair

Issue 03 | 2012

access to raw material. Raw material agreements, such as the agreement of the Federal Republic with Mongolia, are a good start. In the future, securing raw material in trade connections should have a central role. On a multi-lateral level, the EU Commission and Federal Government should stand up more clearly for an improvement of WTO trade rules and reduction of trade barriers, such as export duties and taxes on raw material, as well as restrictive subsidies (e.g. dual pricing). However, access to raw material is also a question of information about stocks, mining projects and political framework conditions in mining countries. The establishment of the German raw material agency DERA by the Federal Government is a contribution to more secured information. Considerations of introducing Europe-wide taxes on raw material use evoke clear opposition: 65 per cent believe such a measure is not meaningful, as opposed to 13 per cent who support it. A higher price of raw material through taxes should lead the enterprises to a more efficient usage of raw material. However, taking into consideration the existing high prices of raw material and the high fluctuations, it is hardly expected that such taxes would have a guiding function. Instead, they would deprive enterprises of financial resources, needed for investments in new technologies and resource efficiency. The management task of each enterprise is and will be guiding raw material use.

Energy and Resource Efficiency: Supporting Instead of Prescribing A critical instrument in facing challenges in energy and resource supply is an efficient use. Each enterprise is interested in increasing its competitive capability through increasing its energy and resource efficiency. Therefore there is no need for legal regulations and the correspondent bureaucracy of control. Enterprises do not flatly reject binding regulations for energy and resource



Fig. 18: Chart 18 [Source: IHKEnterprise- Barometer 2012]

efficiency: After all one third believe this measure is politically meaningful. As an example, producers of products and plants that are highly energy efficient or energy consultancy firms feel that the impulses of efficiency requirements are desirable. This shows that regulations can also create markets. As such the compulsion for investment in new production techniques creates a welcome marketing potential in other places. However, there is agreement mainly among service enterprises (41 per cent), whereas in industry, which is significantly more affected by such regulations, only 20 per cent believe governmental regulations are meaningful. Many entrepreneurs believe that governmental regulations should not turn into rigid and excessive efficiency regulations: 36 per cent feel that such political measures would not be meaningful. Among the enterprises in the industry, 47 per cent are critical towards binding regulations, because such minimum efficiency standards allow for governmental intervention in production and product development, as well as intervention in the balance between supply and demand. As such they can block the innovation of enterprises and stop economic growth. Therefore, in order to increase energy and resource efficiency, the economy does not primarily focus on politics, but sees it as a creative measure on their own responsibility to improve their competitiveness. Taking into consideration the existing significant efficiency potentials which can economically be developed, it is recommended that politics exhausts all possibilities of providing information, before resorting to legal force. In line with this spirit, already in 2009, the IHK organization has formed a “Partnership for climate protection, energy efficiency and innovation” with the Federal Government, with the aim of advancing the subjects with the initiative of the economy. The project, which places emphasis on qualification and information, has already reached 20,000 entrepreneurs in various events. (Further information can be obtained from: http://klimaschutz

Issue 03 | 2012

The enterprises also would welcome the support of politics in increasing energy and resource efficiency, through more attention to new technologies and research: 85 per cent of enterprises request an improvement of new technologies, and 83 per cent call for the expansion of technology friendly advancement of energy and raw material research. As such, political measures in this direction are top requests of the economy. This is not surprising, as a technology friendly FuE advancement can lead to development of solutions, which can contribute to securing supply of raw material and energy and to global competitive ability of German enterprises, both effectively and in real-time. Hereby the central issues are – particularly with regard to the energy turnaroundthe development of intelligent networks (smart grids) and storage technologies, as well as all areas of research, which have a direct reference to the added value of enterprises, like for example new business models. The Federal Government has already taken the right steps in this direction. As such the 6th energy research programme of the Federal Government (Research for an environmental friendly, reliable and affordable energy supply – the 6th energy research programme of the Federal Government, August 2011) has announced stronger systematic research funding. The Helmholtz Institute for resource technologies in Freiberg was established in 2011 for raw material. The institute is mandated to develop technologies for efficient and sustainable feedstock industry. The European research cooperation for increasing energy and raw material efficiency should also be strengthened, for example as an element in the European research supporting programme (Horizon 2020) or as innovation partnership.


TRANSFER OF TECHNOLOGY The enterprises believe there is a great need for political action with regard to the framework conditions for new technologies. Innovative technologies, like for example technologies for storage of electricity or for separation and storage of CO2 (CCS) are not well accepted in society and politics. As such the needed CCS law for demonstration projects has not been passed in Germany. This means that there can be no research in the biggest industrial country of Europe. In addition, other recent surveys like the DIHK innovation report 2011 (DHIK innovation report 2011 – Innovation dynamics of German enterprises is unbroken, December 2011) show that generally the lacking acceptance of technology and innovation is increasingly seen as a barrier to changes that are conducive to competition in the economy location Germany. Therefore politics should take measures to increase acceptance and also foresee these measures as a building block for advancing research. Initiatives, such as the platform “Sustainable energy networks” for BMWi, in which DIHK is involved, are steps in the right direction. Together with the economy, science and the public, information barriers need to be removed.

Large Gear Units for Powerful Crushers

SEW-EURODRIVE industrial gear units for giant mining equipment


round the world, the raw materials industry plays a strategically important role. For an iron ore mine in Brazil, ThyssenKrupp Fördertechnik manufactures a mobile crusher system used for excavated material. For this application, ThyssenKrupp Fördertechnik, based in Essen, commissioned SEW-EURODRIVE with supplying industrial gear units. The drive specialist, based in Bruchsal, has locations in 45 countries, making it a reliable partner in Germany’s exportoriented systems engineering sector.

ThyssenKrupp AG, headquartered in Essen, is one of the largest, globally active technology companies with a long tradition. It employs 180,000 employees worldwide. In the 2010/2011 fiscal year, the company reached EUR 49 billion in sales. The company’s activities in roughly 80 countries include plants, systems, components and high-performance materials. In the two divisions of Technologies and Materials, the activities are grouped into a total of eight business areas. In its Area Plant Technology business, the company is active internationally as a supplier in special and large industrial plant manufacturing. This business area includes ThyssenKrupp Fördertechnik GmbH, which has several locations in Germany and companies and offices in twelve countries, including Australia, Brazil, China, India, Russia, South Africa and the USA. Its core competencies are in mining technology for coal, minerals and excavated material, processing technology as well as cargo handling technology and systems for bulk material in harbor terminals.

Wherever large amounts of earth and materials need to be excavated, mining technology from ThyssenKrupp Fördertechnik (TKF) will be involved. TKF’s bucketwheel excavators, belt conveyors and spreaders can move enormous quantities of material – well beyond 200,000 m3 per day. “Crusher systems crush excavated material into pieces suitable for belt transportation directly at the excavation site. The material can then be transported economically and continuously

Issue 03 | 2012


TRANSFER OF TECHNOLOGY with the help of belt conveyors. TKF was deeply involved in Essen and Ennigerloh in the development of these crusher belt conveyor systems,” explains Johann-Dieter Wiekhorst, Senior Engineer Drive Systems in Mining. Today the company is one of the world’s leading manufacturers in this sector. A prototype of this fully mobile crusher has already been operating in China for several years.

Exploiting iron ore at the mine Vale is a Brazilian mining company that claims to be the second largest in the world and the largest producer of iron ore. It has locations on all continents, including several in its home country. Parauapebas is located a good 1,000 km north of the capital city of Brasilia in the state of Pará. Located close to this medium-sized city is the Carajás N4E mining complex. This is the site where Vale Mining is exploiting iron ore. Yet before the valuable raw material can be drawn out, the earth must first be stripped, broken up by a crusher and then further transported. Power shovels remove a layer of earth roughly 15 m thick for each section (excavation level). Projected for a year, a single crusher can smash roughly 20 million tons of excavated material. Vale has previously used heavy-duty trucks in mining to remove these massive amounts of material. With their high power, these vehicles also consume large quantities of diesel. Even the oversized tires add to costs as they need to be replaced on a regular basis. So the operators decided to use giant mining equipment instead. Vale commissioned ThyssenKrupp Fördertechnik with the construction of two crusher belt conveyors. This new equipment will help lower operating costs and reduce CO2 emissions from operation.

Mobile crusher system “The entire system is centered around two fully mobile crushers (MCs) that crush the excavated material. This mix is then conveyed by two belt wagons to a belt conveyor, which transports the mix over a distance of several kilometers. Later, the excavated material is removed by a tripper car and dumped over a spreader,” explains Matthias Kasselmann, Senior Project Manager in TKF’s Mining division. Then he adds: “We supply complete fully mobile crushers and all other core component units such as gear units and ball slewing rings. Our Brazilian subsidiary in Belo Horizonte, about 350 km north of Rio, provides the rest of the components and assembles everything together.” The type designation of the fully mobile crusher is MC 3900. It sits on a crawler-mounted machine and weighs a total of roughly 1,500 tons. The crusher is 17.5 meters tall and almost as wide. With its boom it is about 50 meters long. The system is designed for 24-hour operation throughout the whole year. The only time it is not working is between shifts, when the belts are moved and when the crusher is placed in a different position. The projected service life of the crusher system totals more than 50,000 operating hours. With an average operating time of around 4,500 hours in a year, the equipment will last for more than ten years, and usually much longer. A power shovel feeds the mobile crushers with 35 m3 of excavated material per minute. This is equivalent to 65 tons of material. In an hour, the crusher’s throughput is about 3,900 tons of excavated material. An apron conveyor transports this material up to the mobile crusher. From here, the material falls into a crushing plant that consists of two rollers rotating in opposition. The rollers have spikes that break up the material. There is an uneven number of these spikes distributed over the entire circumference.

Energy in XXL-format

This prevents the same opposing spikes from pairing up with every rotation, which would lead to increased wear at individual places. The crusher has a torque of 400,000 Newton meters. (For comparison: Depending on engine size, a sports car has about 350 Nm to 600 Nm.) Once through the crushing plant, the excavated material winds up on the boom of the crusher. The boom swivels around a slewing drive so that it can always be directed towards the next belt wagon while advancing the extracted goods. It has a mobile trolley and two booms: One points in the direction of the crusher, the other towards the conveyor belt. This giant mining equipment transports the excavated material from the unit or crusher to the belt conveyor. “A belt wagon can span distances of roughly 100 meters. This means that the belt doesn’t have to be moved as much. When the distance between the crusher and belt conveyor is larger, the belt section has to be moved up,” explains Senior Engineer Johann-Dieter Wiekhorst.

All movements on the mobile crusher are controlled by electric drives. The energy for the giant mining equipment is supplied through a 6-kV line. Smaller currents flow at the specified power demand because of this high voltage level. This means that the cable diameters can also be smaller. The “small” here is relative: The cable is roughly 25 centimeters thick and one kilometer long and is routed on a cable drum carrier, which moves above the belt conveyor. Its drum is five meters long with a diameter of approximately three meters. The carrier supplies all giant mining equipment with energy. Here a cable carrier and electric cable run through the belt wagon to the crusher. Since the giant pieces of equipment need to communicate with one another, signal leads and other media, such as water or compressed air, are lead through the cable carrier to the crusher.

Represented globally – on site locally A project of this size is created over a long period of time and great distances. The total duration of comparable projects – from awarding the contract to handing over the project to the customer – often stretches out over three years. The individual components of the giant mining equipment are supplied and manufactured around the globe. Matthias Kasselmann states: “The steel construction and purchased parts come from Europe.

the Morsleben radioactive waste site (ERAM):

In-situ roadway stopping in rock salt measures

An in-situ feasibility test is to be carried out at the Morsleben radioactive waste site (ERAM) in order to verify that, as part of the care and maintenance plan for the former waste repository, salt-concrete structures can be used to create a safe and reliable stopping in horizontal mine roadways.

Background In Sachsen-Anhalt an der Grenze zu Niedersachsen befThe former Morsleben Radioactive Waste Repository is located close to the town of Morsleben in SaxonyAnhalt, close to the border with Lower Saxony. The plant is operated by the DBE (German Service Company for the Construction and Operation of Waste Repositories. The client is the German Federal Government, as represented by the BfS (Federal Office for Radiation Protection) Salzgitter. The installation, which was in operation until 1998, remains the only approved repository for radioactive waste in the whole of Germany. The mine was used for potash production up to the early 1920s and then switched to mining rock salt until the end of the 1960s. During the Second World War parts of the mine were used as an armaments factory and inmates from the Neuengamme concentration camp were put to work there.

Issue 03 | 2012

When salt production ended the nuclear plant operators of the then GDR acquired the site in 1970 with a view to using the mine for the storage of low- and medium-level radioactive waste. Storage trials subsequently commenced in 1978 and in 1986 the relevant GDR authorities issued a long-term operating permit. On the basis of this permit, which retained its validity after German reunification by way of a specific provision in the Unification Treaty, radioactive waste continued to be stored at the site after a brief interruption from 1994 to 1998. A total of 6,621 radioactive sources and some 36,752 m続 of radioactive waste are now stored in the mine, with about 60% of this material having been deposited during the period 1994 to 1998. The solid waste material, which is contained in drums of 200 l to 570 l capacity, was stored on mine level 4 (at a depth of 500 m) in the former stope workings and also in specially excavated cavities. The liquid waste was first solidified with lignite filter-ash.

Project remit The underground storage operation was discontinued in 1998 and in 2005, when it was decided that the facility would no longer be kept in service, work began on the planning of a care and maintenance phase. Investigations revealed that the underground workings exhibited stability problems due to the high excavation ratio – a legacy from the many years of active mining operations. Many of the cavities (former stope workings) have already been filled in, with Thyssen Schachtbau GmbH already having played a major role in this operation (see Thyssen Report 2004). In 2009 the BfS submitted the documentation relating to a nuclear planning approval procedure for the closure of the ERAM facility. As well as additional stabilisation work in those cavities and storage chambers that are still open the decommissioning plan includes the construction of stoppings at various points along the horizontal mine roadways. These will serve as important elements in the overall safety plan being developed as part of the longterm safety guarantee for the facility. These roadway seals will separate the general mine workings from the waste storage areas and will prevent any potential nuclide transfer. In-site tests are to be carried out to confirm that such stoppings are fit for purpose (insitu trials on a 1:1 scale under real conditions).

Issue 03 | 2012

These in-situ tests have been the focus of a number of different studies in recent years, with much of this work – in which Thyssen Schachtbau GmbH and its subsidiary TS Bau GmbH played a major role – being undertaken in collaboration with institutes and universities, including the Freiberg University of Mining and Technology, the Institute for Deep Geological Disposal, GSF (National Research Centre for Environment and Health) Munich, the Fraunhofer Institute Dresden and the IFG Leipzig. Many different practical tests and trial constructions of seals and stoppings were also undertaken in order to examine the functional viability of the sealing elements and these activities yielded much valuable information for follow-on projects. In March 2010 the contract to erect structures for the ERAM facility was put out to public tender. As Thyssen Schachtbau GmbH and TS Bau GmbH had already constructed similar stoppings in other collieries the two companies set up a consortium with Schachtbau Nordhausen GmbH in order to bid for the contract. This partnership was eventually preferred over four other bidding companies and after extensive planning and preparatory activities the actual underground work began in September 2010.




The contract provided for the construction of a 25 m-long roadway stopping. This structure was to comprise a number of different elements, namely a sealing body (M2 grade salt concrete), a contact zone, a disturbance zone in the rock salt and a plastic joint. The Morsleben operators built a stub roadway with a cross section of 20 m² specifically for this purpose.

The operation to construct the roadway stopping commenced on schedule in September 2010. After setting up the work-site the first operation was to erect shuttering close to the proposed roadhead. This was needed for the construction of a salt-concrete face with a precisely defined slope and surface roughness.

A borehole was also drilled from another roadway, which was also specially driven for the purpose above and to the side of the target road, in order to reach the front of the stopping – which would eventually no longer be accessible. This borehole would later be used to apply pressure to the stopping in order to verify its leakageresistance. As well as building the structure itself the contract also provided for the installation of an extensive range of measuring devices for monitoring the condition of the stopping. Before the actual structure was built a large number of injection hoses, which would later be used to carry a sealing suspension, were laid into the area to provide a means for injecting sealant if a contact joint were to open up at some future point between the body of the stopping and the surrounding salt rock or the disturbed zone/fissured zone.

Issue 03 | 2012

This was followed by the installation of the pressure chamber and control chamber. Slits were then made in the injection hoses around the circumference of the roadway profile at intervals of 0.75 m. These would be needed for the secondary-injection phase. Additional equipment was also installed for the concreting phase. A wide range of measurement devices were also incorporated into the roadway roof, face and sidewalls. All the injection hoses were then laid towards the ‘fresh air side’ via a cladding tube suspended in the centre of the open roadway. The cables for the measurement sensors were run through additional core drillings into a parallel

TRANSFER OF TECHNOLOGY heading specially driven for the purpose. This was also to serve as the central node point from where all the geotechnical measurement devices would be monitored and controlled. The airside shuttering was then erected and the concreting plant set up. The latter had built-in redundancy and was designed to fill the 500 m³ of void ‘wet-in-wet’ at the rate of 20 m³/h. The operation to fill the roadway and construct the initial stopping began on schedule the week before Christmas 2010. This phase was also completed successfully. The first pressure tests were then carried out after a 60day curing phase and the removal of the airside shuttering. It became apparent that – as anticipated – a contact joint had formed between the salt concrete and the strata. This created a leakage when compressed air was applied to the structure. In February 2011 secondary injection commenced as planned into this contact joint and any disturbed zone that might be present in the salt concrete. The injection hoses laid around the circumference of the roadway were filled with a special suspension in accordance with a carefully regulated routine. The pressure and volume of the suspension was monitored by a comprehensive array of measuring instruments.

Summary The experimental stopping constructed as a consortium venture with TS Bau GmbH and Schachtbau Nordhausen GmbH has to date fulfilled all expectations. The structure has shown that it is both theoretically and practically fit for purpose as a horizontal sealing element for underground roadways as part of the planned decommissioning of the ERAM facility. The successful completion of the stopping has given THYSSEN SCHACHTBAU GmbH another opportunity to demonstrate that its skills as a specialist mining contractor also extend to areas outside shaft sinking. This is the third such stopping to be successfully constructed in rock salt strata, following the horizontal seals already erected at the Teutschenthal and Sondershausen mines.

The fourth part of the excavation programme commenced in 2008: The north and south shaft connection via lateral roadways C467 and C432 and the completion of the inset extensions. The first phase of this operation was described in REPORT 2010.

Prosper-Haniel colliery An ongoing development plan for mine level 7 in shaft number 10 district is now a crucial factor for ProsperHaniel colliery if the mine is to remain an efficient coal producing unit in the years ahead. The excavation of the south shaft landing has been an important part of the overall expansion programme.

Planning phase The planning of the ‘south landing’ development project was based on experience acquired from the north installation as well as on geological exploration data from core drillings. This informa tion helped establish the technical ground-rules and plan out the permanent support system.

1. In order not to compromise the rigid support lining of the existing landing the new inset would have to be driven out from the shaft side. 2. The final cross section (approx. 100 m2 of clear space) was to be excavated in a series of stages/part sections. 3. The final support system was to comprise a combination of immediate-bearing shotcrete, systematic rockbolting and backfill of various thicknesses, plus standing supports.

Excavation concept After laying down the general operating parameters, detail plans and variant designs the technical strategy was discussed and agreed with the client. A fixed working stage was erected for roof excavation work in the existing landing. This stage was to perform the following functions:

The results obtained from a numerical model prepared by Essen based DMT GmbH & Co. KG indicated that the following approach would have to be used:

Issue 03 | 2012


TRANSFER OF TECHNOLOGY • To provide an operating base for a drill jumbo and loader unit

Local front face at the level of the bottom stage

• To act as a safe shotfiring refuge for number 10 shaft • To serve as a reception point for blasting debris from the first shotfiring phase • To allow efficient clearing of debris to the bottom-level platform • a materials transit point and transport route • As a travelway for the drivage team and storage point for tools and instruments.

A vertical section taken through the landing, showing the existing and proposed profiles, clearly illustrated the scale of the project and the problems that the operation would pose. The working stage was constructed and delivered by Maschinenfabrik Hese GmbH. A repositionable hatchway was built into the structure to allow debris to be transferred through the stage and on to a chain conveyor installed on the floor platform. A type BTRL 1 drill jumbo was chosen for the excavation and rockbolting work, this decision being based on the machine’s low overall weight of only 12 tonnes. As most of the rockbolts to be used would be four metres in length the jumbo was fitted with a telescopic drill slide designed for extension drilling work. A Bobcat loader was chosen for debris clearance. Though an unusual choice for a colliery based project the Bobcat, which first had to be modified for the job, was preferred because of its low unladen weight

and excellent manoeuvrability for a machine in this class. The excavation project also included extending the shaft landing by a total of 24 m. This comprised a conically tapering section some 16 m in length and a further 8 m of cavity with a profile to match that of mine infrastructure roadway C432.



Design of the part cross sections

Excavation of the south shaft landing – operating experience Unlike the north landing project that was completed in 2008/2009, which had been a stand-alone operation completely unrelated to any other activities under way at the time, the work to be undertaken in the south landing was to prove much more extensive and complex. Scheduled materials and personnel transport movements would have to continue in parallel with the excavation work and additional activities would also have to be carried out as part of the technical installation work for the shaft inset on mine level 7.

Equipment installation and preparatory work The conveyances and all necessary machines and equipment were assembled and installed in line with the detail plans for the drivage concept. This was followed by the installation of two blasting screens – one fixed screen was set up in the immediate vicinity of the shaft and another mobile screen was positioned right up against the heading face. The mobile design of the roadhead screen meant that an additional and

TRANSFER OF TECHNOLOGY Excavation work Drivage operations commenced in the pilot roadway (part- section 1a) at the end of September 2009. Lengths of up to about 8 m were blasted out in four rounds of shots. It was decided to use a parallel cut with eight 100 mm-diameter clearing holes. The advance per round was initially 0.8 m. From 8 m into the drivage until the end of the pilot tunnel firing was based on two rounds of shots with a maximum advance per round of 1.6 m. The Bobcat proved to be an outstanding loading machine. Its mobility and acceptable loading performance meant that it remained in service until partsection 1c was completed. Unlike its track-mounted counterparts, however, the Bobcat vehicle needs a level road surface for its operations. The performance of the BTRL 1 drill jumbo also impressed the drivage crew and the machine proved to be well up to the job of drilling the shotholes and setting rockbolts of various types. A sliding track system mounted on the working stage meant that the jumbo was able to deploy easily to different positions. After completion of the pilot drivage at the end of November 2009 section 1b was driven eastwards followed by 1c westwards.

The supports were then installed in sections working outwards from the roadhead. The figures below show the individual drivage sections and the installation of the steel supports in the top slice. The infrastructure roadway C432 was driven at the same time as the operation in the south landing. After the steel supports had Steel support in section I with props been installed in section I of the landing extension all was ready to make the cut-through from infrastructure road C432 to the south shaft inset. The steel supports in the top slice were reinforced with additional floor arches and struts in order to create the necessary stability for the superstructure when excavating the lower sections, and also to counteract any convergence movements. The colliery surveying team carried out twice-weekly convergence checks as the drivage work progressed. Telltale extensometers were also installed at various control points. These two monitoring systems concurred in finding no increase in measurement levels compared with the numerical model predictions. The excellent progress made in the C432 cut-through, combined with the fact that virtually no convergence was recorded, led the engineering team to rethink their strategy for driving sections II and II of the shaft inset.

Issue 03 | 2012

It was consequently decided to depart from the original plan and to excavate the next sections from C432. There were a number of important advantages in adopting this approach:


TRANSFER OF TECHNOLOGY Start of steel support assembly in the roof section

1. By turning the debris clearance direction towards C432 it would be possible to carry out assembly and installation work in the shaft zone in parallel with the drivage operation 2. The use of larger and more powerful machines and equipment would help increase drivage performance 3. The permanent inset support system could be installed in as short a time as possible 4. Separating the operations under way in and around the shaft would help increase safety levels at the workplace.

After infrastructure roadway C432 had been fitted with its type A combination support system as far as the shaft inset, work could begin on driving sections IIa and b. Cavities were excavated in succession to the east and west sides and the rockbolts and/or shotcrete lining were set in place. The advance per round was about 1.2 m. After every three pulls had been completed with rockbolt-shotcrete to provide support the final steel supports were installed in this section and backfilled.

TRANSFER OF TECHNOLOGY This routine ensured that as the drivage approached number 10 shaft only a short section of roadway was ever standing under temporary supports. Even during this phase of the operation the convergence monitoring instruments failed to indicate any unusual events. Once a separate shotfiring screen had been set up the breakthrough to the shaft zone was achieved after several rounds of shots. In order to eliminate all conceivable risks it was decided to leave the inverted arches of the top slice in place as additional security until the permanent ring supports were installed. The bottom slice was then excavated via a drivage ramp. The requirement in this section too was to have as short as possible a delay until the installation of the permanent support system. For this reason the roadway profile was again removed in sections, rather than excavating the entire face all at once. Unlike the approach adopted in the overlying sections, however, the embedded arch supports were installed and backfilled as complete units. After the cutthrough had been made to the number 10 shaft cellar and the supports had been installed the remainder of the excavation was completed towards C432. The permanent support system was also installed in this area. An end-wall was additionally constructed at roadway C432 to seal off the zone with the embedded

floor arches. Work began at the same time on erecting the steelwork needed to fit out the shaft inset. The shotfiring screens and working stage for section I were partly dismantled in order to create additional working space. The excavation machinery was then dismantled and taken away. After completion of the steel girder platform in the south landing the remaining floor arches could be removed from section I.

Summary 1. The overall concept used for excavating the south inset proved to be highly successful in practical application 2. The drivage work was completed within schedule 3. The restrictions imposed on number 10 shaft operations remained within predetermined limits and hold-ups only occurred when shotfiring was being carried out

Fit for the toughest challenge: The Ceramax pH sensor

Maintenance-free pH measurement technology in the wastewater treatment system of concrete production plant by Martin Freudenberger Endress+Hauser Conducta GmbH+Co. KG Gerlingen | Germany

he Ceramax from Endress+Hauser looks different to normal pH sensors. That‘s because it is! Once installed, it measures for many years with virtually no need for maintenance, even under T the hostile process conditions of Vorarlberger Lieferbeton‘s concrete production facility. This is all thanks to the extremely robust, glass-free design with enamel measuring diaphragm.

A tough environment for sensors The production facility at Vorarlberger Lieferbeton is just like any normal concrete production plant and is therefore a very challenging environment for a sensor. Sludge, dirt, and alkaline solutions with a pH value of up to 13 mean that the process environment is such that pH sensors are pushed to the very limit of their capabilities. Additional challenges are the abrasive effect of the solid components of the concrete wastewater and also the fine particles, which can quickly block the diaphragms. Faults and failures are a daily occurrence. Indeed, the measurement technology currently available seems more suited to the measurement of droplets in the pharmaceutical industry than to the heavy-duty business of concrete production. Vorarlberger Lieferbeton, one of the largest manufacturers of concrete in western Austria, finally made the leap and switched to the new Ceramax pH electrode from Endress+Hauser. They installed the sensor in the wastewater neutralization process. After several months in use, the Ceramax has been providing continuous and reliable measured values without the need for calibration. The production staff are spared the additional work of maintaining the sensor, while the quality of the wastewater has improved significantly thanks to continuous measurement and a treatment process closely attuned to these measurements. Patrick Raunegger, Plant Manager at Vorarlberger Lieferbeton, claims „Since it was first put into operation, Endress+Hauser‘s Ceramax delivers extremely accurate measured values. It is not least thanks to the Ceramax that the system‘s cleaning performance has been elevated to a high standard. Todate, no intervention has been required to maintain the measuring line.“

Fig. 1: The Ceramax is extremely long-lasting thanks to its robust design.


TRANSFER OF TECHNOLOGY What are the real capabilities of the Ceramax? Standard glass pH electrodes quickly reach their technical limits in this type of application. On the one hand, there is always the risk of glass breakage, resulting in the failure of the measuring point. On the other hand, the actual part of the sensor which is sensitive to pH is the glass ball which, due to its small surface area, can quickly become dirty or coated. This necessitates permanent cleaning and regular, time-consuming calibration. The Ceramax CPS341D uses a completely different approach. The sensor substrate consists of stainless steel and is therefore mechanically stable when it comes to suspended solids and even turbulent flows in pipes or agitators. This also means that the Ceramax electrode can be installed directly in the sample stream without the need for an additional basket protector. The pH-sensitive material used in the Ceramax is enamel, which is applied firmly to the steel substrate during a complex burning process comprising multiple stages. In the course of this process, the complete electrode shaft is coated with blue enamel to make it resistant to corrosion. At the lower end of the shaft, the pH-sensitive yellow enamel is melted on in rings. This means that the pHsensitive measuring surface is approx. ten times greater than in the case of glass electrodes, thereby significantly reducing the possibility of dirt sticking to it. In addition, the large smooth surface makes the electrode easier to clean. Usually the flow velocity of the process medium is sufficient to clean the sensor.

process data are stored directly in the Memosens plugin head. The high-grade construction of enamel on steel guarantees the long-term stability of the electrode. Depending on the application, the electrode must be recalibrated once a year at the very most. The electrode is therefore virtually maintenance-free. Moreover, Memosens technology eliminates all kinds of moisture-related errors which make life difficult for operators using conventional pH sensors.

The Ceramax electrode is equipped with Memosens technology i.e. the sensor is precalibrated in the factory and can then be used immediately in the process. Important

However, it‘s not just as a heavyduty electrode that the Ceramax has proven its worth. As it can be cleaned in accordance with EHEDG criteria and comes with the relevant certificate, it is CIP-capable and sterilizable. This makes it attractive, for example, to the food and biotechnology industries too. Summary: Wherever pH measurement technology with long-term stability and a long operating life is required.

odern cropping technologies require systems capable of transporting bulk materials quickly and efficiently from the quarry to the destination, and through rough terrain as well. Often trucks are used in this regard. Depending on the nature of the terrain, however, trucks rapidly reach their limits as they need, for example, well-developed roads. The costs arising for construction, maintenance and possible extension are not insignificant. In addition, all of this implies serious landscape changes. The emissions caused by truck traffic are undoubtedly high, both with regard to toxic substances and to noise and dust. BEUMER develops and installs curved belt conveying systems, which ensure efficient and environmentally safe transport also in rough territories. A comparison follows. Belt conveyor or truck? This question was raised at Asia Cement Group, a large building material manufacturer headquarter in Taipeh (Taiwan): approximately 30 km separate the quarry from the newly constructed plant. The requirements were clearly defined: the limestone has to be transported rapidly to the plant, which is provided with two kiln lines each having a daily output of 4,200 tons. For this, Asia Cement Group needs daily 14,000 tons of raw material. The building material manufacturer had the option of choosing between transport by truck or belt conveying system. Due to the fact that the terrain consists of mountains and bamboo woodland, the trucks would have had to drive mostly via public roads. This would have caused detours, slowed down transport times and raised costs. Asia Cement chose the troughed belt conveyor of the intralogistics expert BEUMER as the costefficient solution.

Considering ecological, economic and social aspects Several companies have to take this decision if they intend to transport large quantities of bulk material such as ore, coal, gravel or sand from the quarry, the mine or the sand pit to the plant or to the harbour as cost-efficiently and quickly as possible. In this regard, trucks present many disadvantages. To build roads is expensive and implies considerable landscape changes. Especially roads dimensioned for dump trucks require a width of approximately 30 metres. Moreover, roads must be maintained. Operational costs and emissions

Belt conveying systems enable a rapid and efficient transport of bulk material from the quarry to the destination also through rough terrain.

caused by trucks are to be added as well - including fuel consumption and personnel costs, as well as noise and dust. The more raw materials have to be transported from the quarry to the plant, the more truck loads have to be undertaken.

Belt conveyors - an efficient alternative Therefore in practice companies must take a closer look at the alternatives. With its belt conveyors, BEUMER provides an economical and environmentally protective solution for bulk material and piece good transport. The belt conveyors are able to navigate long distances, high angles of inclination and tight curve radii, and can be adapted individually to the respective application and topography. The landscape changes are minimal and meet even the highest environmental protection requirements. Durable conveyor belts guaranteeing tensile strength are used. BEUMER makes use of different dimensioning programmes to determine the ideal belt design. In this way, tractive forces or loads arising by acceleration and delay also can be calculated - and this always considering the net weight of the belt and material transported. Possible curve radii are also calculated with this programme. BEUMER provides preliminary feasibility studies in this regard. Furthermore, the belt position in the corresponding curve radius is pre-calculated for empty and loaded belts thus enabling the optimal adaptation of the belt conveyors to the local environment. Due to their slight Now Asia Cement Group relies on the advantages of the BEUMER belt conveyor.

TRANSFER OF TECHNOLOGY routing, the belt conveying systems negotiate rugged terrain and other obstacles, such as rivers, streets, buildings or train tracks. Horizontal and vertical curves can even overlap. Except for support columns and steel structure that need to be constructed, the landscape is not subject to changes. Companies save significant costs, including those typically arising for example in connection with earthwork, and even in difficult environments the construction work for these systems is minimal. In addition, belt conveyors represent an environmentally friendly solution, which can therefore be adopted also in nature reserves. The direct routing enables a considerably faster material transport than by truck. In addition, fewer personnel is required for operating the belt conveyors. A further advantage related to the use of belt conveyors instead of trucks and implying additional cost saving is the minor energy consumption that at the same time reduces the CO2-emissions. Depending on the project, belt conveying systems require up to 90 % less primary energy than comparable truck transports. A concrete project-related comparison discloses that, merely due to the consumption of diesel fuel, trucks require a specific primary energy of 11.4 kwh for each ton of transported material. In contrast, the belt conveying system that was constructed later requires only 1.44 kwh. If, as in this case, 7.5 million tons raw material are transported annually, the use of belt conveyors means a total saving of 74 million kwh per year. This corresponds to an energy consumption of more than 20,000 single-family houses. Solely by saving diesel fuel, the operational costs of the company are reduced by more than 5.5 million Euro per year.

Issue 03 | 2012

Environmentally friendly transport Depending on the requirement, BEUMER provides open troughed belt conveyors for higher throughput, larger mass flows as well as larger curve radii, and closed Pipe Conveyor for products that need to be protected against environmental stress. These are used also in topographically challenging terrain that requires small curve radii and large angles of inclination. In order to minimise dust formation during transport, the open troughed belt conveyors can be covered or encased. This sealing ensures a dust-free transport. However, things are completely different for trucks: considerable dust quantities arise during transport. The dust is dispersed on the loading space and causes substantial environmental pollution. In order to minimise this, roads are for example sprinkled with water. This represents not only an immense expenditure, but in regions suffering water shortages this process is simply impossible. In addition this water - mixed with oil, tyre abrasion or bound contaminants - flows back into the ground water.

The advantages of the Pipe Conveyor are, for example, the protection of the material from the elements and protection of the environment by means of dust-free transportation.


TRANSFER OF TECHNOLOGY Belt conveyors are additionally provided with environmentally safe electric drives and low-energy belts. Therefore, especially in times of climate change and increasing greenhouse gas emissions they are considered a ‚preferred option‘. The motors - which, depending on the topography are run in motor-driven and regeneration mode - are mostly adjustable. This permits an optimum load distribution on the drive unit in different operating conditions. If the belt conveying system conveys downhill, the system works in generative operation. The generated electric energy is fed to the mains by a regenerative feedback unit. This way the operating costs of the complete system can be further reduced.

A further advantage of the belt conveying system is the low noise emission. They operate quietly and meet also strict environmental regulations. Specific idlers, noise-reduced bearings and low-noise electric drives make sure that belt conveyors are so quiet that they are often the only alternative to material transport in nature reserves or in inhabited areas. Dump trucks, on the other hand, generate a very high level of noise. A 180 tons truck can generate a noise level of up to 123 dB and is therefore approximately as loud as an alarm siren. Compared with a belt conveying system this, noise is seven to ten times louder. Furthermore, there is the noise generated while loading and unloading the trucks.

In an interview with the organizer of bC India, bC Expo India, Shushmul Maheshwari, spokesperson of the Research Company RNCOS, and Anna Westenberger, spokesperson of Germany Trade and Invest (GTAI), outlined the current situation of the Indian market..

bC Expo India: What is the most unique feature about the Indian construction industry? Shushmul Maheshwari: The Indian construction industry is highly fragmented. This is partially due to the fact that, for most projects, there are no long-term relationships between the contractors and clients and partially due to the fact that the sector in many cases lacks economies of scale. Thus, smaller players may have better cost structures due to lower overhead costs. Furthermore, one has to differentiate between the organized and the unorganized segment of the sector. The organized segment consists of firms and independent contractors who manage their business on a more professional basis and operate on small and medium as well as large scales. The unorganized segment primarily consists of stand-alone contractors that operate at a small scale. What does that mean for the demand for construction equipment?

SM: India, as the world’s seventh largest country by area and second biggest by population, is one of the most dynamically growing, but largely untapped construction equipment markets. In the recent years, the country


TRANSFER OF TECHNOLOGY has witnessed massive investment in the construction industry from both public and private enterprises. Multibillion dollar investments in constructing roads, ports and power plants, and developing telecommunication sector and urban infrastructure have paved the way for the construction equipment demand to grow phenomenally. Industry experts predict the market growing even faster for the coming years. From 2010 to 2020 it is estimated to grow six times to a size of 20 to 25 billion US dollars.

But won‘t the recent slowdown in economic growth affects this trend? SM: According to our research report, “Booming

Construction Equipment Market in India”, the Indian construction equipment industry has been witnessing a consistent double-digit growth over the past few years. Though the economic slowdown had its moderate effects on the industry, it regained momentum in 2010 showing a stupendous growth which is expected to continue in the years to come.

Anna Westenberger: The construction equipment market did indeed grow slower; nonetheless we are still talking about five per cent annual growth. The reason for this decline lies in growing uncertainties regarding the market and its regulations as well as rising capital costs. In the medium term we are still not worried. Especially the demand for low-budget housing will very likely not decline, especially if one takes into account the rapid growth of India‘s metropolises. What are the main drivers for this growth? SM: The earth-moving segment, in particular, has been driving the overall construction equipment industry in India, with the strong demand emanating from the governmentbacked infrastructure projects. The segment is poised to register a remarkable compound annual growth rate of around twenty-one per cent during 2011 to 2015, as per our estimates. AW: We also expect significant growth from

infrastructure. The current five year plan of the government, which covers the period up until 2017, includes doubling the investments in this sector compared to the recent one. Big investments are planned to expand the countries energyand water supply as well as roads and the train network. Furthermore, several ports and airports are in planning or already being built.

Issue 03 | 2012

But India is still behind when it comes to the market for construction machinery and equipment?

AW: As long as labor costs are comparably low, at least

smaller firms will shy away from the investments that come with that sort of equipment. India‘s highly fragmented building sector still hosts a significant number of these. Especially if we are talking about smaller building projects, the smaller builders often have an advantage, since they offer cheaper labor compared to the big competitors. But even as we speak, the circumstances are changing. There are two main factors that make a growing construction equipment market very likely. The number of larger projects is growing strongly. With those, heavy machinery is without alternative if companies want to build beyond a certain size. Especially in the metropolises many new buildings have reached a size which is impossible to build without the help of professional equipment. The second factor is the time. The more the sector is professionalized, the shorter the schedules become. Manual labor may still be cheaper, but it will consume more time. And that is time that especially the large builders are not willing to afford.

What can the Industry do to foster the expected growth? SM: It is a major task for the industry to adapt to the expected growth. India‘s worldwide market share in the industry already tripled to six per cent from 2004 to 2010 and will continue to grow. Companies therefore have to adapt on multiple fronts. One of them is the collaboration with the suppliers, another is improving the competitiveness. This means, for example, to create new products which suit the Indian‘s customers demands and to continuously upgrade the skills of the sales force.

TungStuds in a test of endurance

Mineral processing machines are subjected to great strains and high levels of wear. Sections of machinery where abrasive materials come into contact with the machine are always particularly susceptible. Any lack of anti-wear protection leads to reduced hours of operation, high maintenance costs and expensive machine failure. In all of those areas the use of tried and tested Betek tungsten carbide tools pays dividends and Betek TungStuds, as an additional anti-wear solution, are also exactly where they ought to be: TungStuds are small wear protection bolts with a core soldered into them of

high quality Betek brand tungsten carbide. They are available in graduated sizes – suitable for all types and sizes of machines. They can be easily welded onto parts of the machine that are particularly susceptible to wear and can be repeatedly replaced without the machine parts themselves wearing down. For a particularly tough trial the TungStuds have now even been dispatched into the desert.

In use around the clock: the terrain leveller fitted with TungStuds (photo: Betek) Side surface of a milling roller fitted with TungStuds (photo: Betek)

The Atacama Desert in northern Chile ranks as one of the most arid deserts on earth. The temperatures there vary enormously from +30°C by day to -15°C by night. There are huge mineral mining areas in the desert. The mining operations extract various ores, rock salt, sulphates, nitrates and iodine. The local Betek dealer organised a trial use of TungStuds in the desert with the Atacama Minerals mine operating company in order to try out the little anti-wear bolts under the toughest of conditions. The trial took place in the Aguas

Issue 03 | 2012


TRANSFER OF TECHNOLOGY Blancas mining region, where iodine is among the minerals extracted. The iodine is a component of what is known as Caliche, a mineral, hardened sedimentary rock that in addition to the sought-after minerals also contains gypsum, sand, lime and stony fractions in various concentrations. The layers of caliche vary not only in composition, but also in thickness. In any one region layers of all sorts of different type and thickness can occur, creating extremely tough condition for the machines being used there. Mineral extraction in the desert runs non-stop, seven days a week. As long as mining conditions permit, the machines work continually, around the clock. The TungStuds were tested on a special milling machine called a terrain leveller, which is used to extract the minerals. As it works, the terrain levellers milling roller sinks deep into the subsurface, which, if they are not protected, leads to major abrasion of the rollers sidewalls. These massive wear problems, which used to lead repeatedly to expensive machine downtime and high maintenance costs, made this type of machine ideal for trying out the TungStuds. With the help of the locally based Betek agent, the TungStuds were delivered to the mining region and in temperatures hovering around 0°C were welded overnight onto the side surfaces of the terrain leveller by employee Juan Carlos Figueroa. In total 3,300 TungStuds were fitted. The next morning, the machine immediately went back into operation and has been running non-stop since then. The TungStuds are providing optimum protection to the sides of the levellers milling roller. Expensive, unscheduled maintenance work on these areas is now a thing of the past.

Benefits for the machine operator • Longer machine / plant operating times. The Betek antiwear solution using TungStuds lasts - varying, dependent on operating conditions - many times longer than traditional solutions • Great potential for saving on running, uptime and maintenance costs • Appliances / machines / plants are consequently more economic to run

Cat® Room & Pillar Solutions

by U. Paschedag Caterpillar Global Mining | GM Underground Products

Fig. 1: Room & Pillar Mining Method


he Room & Pillar mining method is used predominantly for underground coal deposits, however also for potash deposits. Coal is not completely being mined out from the underground deposit, but pillars are left standing to keep the roof from caving in. This well-known mining method is predominantly used in the USA, South Africa and India. Furthermore, Room & Pillar machinery is also used for entry development in longwall mining where suitable (mainly USA and Australia). Caterpillar, following the acquisition of Bucyrus in the summer of 2011, now offers a complete range of machinery for this mining method. In this paper, the Cat® Continuous Miners, Roof Bolters, Face Haulage Systems, Utility Vehicles and Feeder Breakers will be described in some detail.

The Room and Pillar Mining Method The Room & Pillar mining method is used predominantly for underground coal deposits, however also for potash deposits. As its name indicates, it mines entries into an underground reserve, leaving pillars sized to the geology to keep the roof from caving in; thus preventing any subsidence. It is mainly used in the US, South Africa and India. There is an extension of this mining method, where the pillars are being mined out back towards the main entries. This allows a high recovery rate, consequently causing subsidence. Finally, Room & Pillar machinery is also used for entry development in longwall mining where suitable (mainly US, Australia and certain mines in other countries).

The main advantages of this mining method are as follows: • Flexibility to mine difficult geometric shapes • Lower capital cost than longwall equipment/section • No down time for face changes • The application of multi-section is spreading the downtime risk.

The main disadvantages are as follows: • Limited dip capability • Requires good roof and floor conditions • Lower production rates as compared to longwall mining.


TRANSFER OF TECHNOLOGY Under Certain Mining Conditions Room & Pillar is furthermore not applicable, such as a dip of seam over 8°, poor roof conditions or poor floor conditions (weight of trackless vehicles). In summary the efficient application of Room & Pillar mining mainly depends upon: • Good roof conditions - adequate “Stand-Up” time • Good floor conditions - free steer vehicles • Dip of the seam (max. 12°, usually up to 8°) • To a lesser degree, depth of the workings • Roadway width • Seam thickness.

Caterpillar Global Mining, following the acquisition of Bucyrus in the summer 2011, offers a complete fleet of mining machines for the Room & Pillar method. In the following, this paper will focus on the following Caterpillar machines: Continuous Miners, Roof Bolters, Face Haulage Systems, Utility Equipment and Feeder Breakers.

Continuous Miners Caterpillar offers a seamless range of continuous miners covering both soft- and hard-cutting applications in any seam thickness. The range includes machines capable of operating in seams from 0,76 m (30 in) to 4,70 m (15.4 ft). As the result of an all-out engineering effort, this complete

TRANSFER OF TECHNOLOGY Fig. 5: Caterpillar Battery FH120 Face Hauler

As a result, the customer can choose from a range of face haulers designed to provide optimal carrying capacity and efficient haulage routes in different mine layouts. Caterpillar offers a line of high-capacity, highly-reliable battery- and diesel-powered face haulers. Whether they’re replacing outdated shuttle cars or current cordless haulers, these offer the most competitive choice for increased productivity. Cableless face haulers have several advantages over cable-driven shuttle cars: They have greater freedom of movement as there are no trailing cables, and travel is not restricted by cable length. They can travel and unload faster than shuttle cars, carry a 15–20% greater payload and operate in narrow roadways with tighter turns. Because of their superior productivity and flexibility, Caterpillar has focused on battery- and diesel-powered face haulers. Each offers distinct advantages. All machines combine compact power, capacity and maneuverability with longterm availability and efficiency.

Cat® battery-powered face haulers do not burden the mine environment with emissions or heat. Due to infinitely variable power control, they are the ideal vehicle for conditions where heat, emissions and noise would impact work and where a flexible vehicle is needed. As the world leader in battery-powered vehicles for the underground mining industry, Caterpillar takes pride in providing the world’s most advanced battery-powered face haulers. Innovative solutions in power control and transmission contribute to making maximum use of battery power. Cat® diesel face haulers incorporate the most efficient engines and power-trains available while boasting the lowest level of general body emissions among underground diesel vehicles. Many proprietary developments – such as dry scrubber and wet bath exhaust systems with diesel particulate filtration and horizontal or vertical configuration cooling radiators – make Caterpillar diesel face haulers a safe and powerful solution for efficient Room & Pillar operations. Since their introduction, Cat®

face haulers have led the industry with state-of-the-art drive technology. The latest Caterpillar innovation is the HiPAC 10 VFD control system, which drives the motive traction and hydraulic systems, and provides the operator with machine management information. The HiPAC 10 is a DC-to-AC variable-frequency inverter control that drives high-performance AC electric motors, which have superior speed-torque characteristics. It is up to 14% more efficient than traditional DC motors. This means higher loaded tram speeds, more responsive hydraulic functions, and more material hauled per battery charge.

The battery driven FH110 and FH120 models allow for payloads of 9 tonnes (10 tons) and 20 tonnes (22 tons) respectively. The 6-cylinder turbocharged diesel driven FH125D allows for 20 tonnes (22 tons). The load discharge time is less than 25 seconds for all three models.

TRANSFER OF TECHNOLOGY Fig. 9a: Caterpillar Feeder Breaker

Utility Equipment With over 40 years’ experience and over 6,500 batterypowered units produced, the Cat® scoop is the obvious choice for a low-maintenance, high-productivity utility vehicle. The products from the No. 1 manufacturer of battery-powered mining machinery are setting the pace in efficient and reliable underground utility vehicles. The SU488 is the strongest and most rugged low-profile scoop ever built. Caterpillar scoops are offered as battery or diesel driven machines with a heavy duty drive train and on-demand 4-wheel drive in tough conditions with heavy duty center section to provide superior stability. The diesel powered versions provide the most efficient engines and power trains available. VFD technology is available for battery articulated scoops. Caterpillar LHDs can be used for a wide range of applications—from general mine transportation and maintenance work to longwall installations and relocations, from cabling and piping installation to stone dusting.

Feeder Breakers Feeder breakers allow haulage vehicles to quickly discharge their payloads. They break mined material down to a “beltable” size and the ratio chains feed the broken material onto a conveyor belt, reducing the risk of conveyor belt jams and spillage. Cat® feeder breakers do the job with a large intake hopper capacity and high throughput rate. The high-speed/high-torque traction system has torque hubs instead of the hydraulic motors used on competitive

models, delivering higher tram speeds for section moves and higher torque-to-ground for greater tractive effort. Caterpillar offers lighter duty machines for typical Room & Pillar production sections with a mining range of 1,07 m (42 in) and higher, capable of process rates of 1.330 tonnes/h (1,470 tons/hr).

Summary The Room & Pillar mining method is predominantly used in the US, South Africa and India. Caterpillar Global Mining offers the complete range of equipment for. The paper has described the most important machines in some detail, such as the Cat® Continuous Miners, Roof Bolters, Face Haulage Systems, Utility Vehicles and Feeder Breakers.

MB products are being used for important constructions in Brazil ahead of the 2014 World Cup An all-Brazilian challenge for the Italian Company MB, leader in the earth moving and construction industry: its products have been in use for several months at various sites across the country.

“We are really pleased with the purchase - the owners confirmed - so much so that in January 2012 we bought another model from the range, the BF120.4, and then in March 2012, the Screening Bucket MBS-18, one of the company‘s newest products”.

Thanks to a partnership with Grupo Monte Sinai Locação Ltda, the MB‘s Crusher Buckets and Screening Buckets have used for the construction of the Arena Pernambuco stadium ahead of the 2014 Brazilian World Cup. It all began in 2009 with initial contact between the Group owners , Abinael Manoel and Enoque Manoel De Souza and MB Area Manager for Brazil, Carlotta Mettifogo. “We purchased the first BF90.3 in May 2011 – the De Souzas explained – and used it for recycling demolished material at the “Atlantico Sul” shipyard in the Port of Suape (Pernambuco). We then took the MB Crusher Bucket to the “Shopping Rio Mar” site to crush inert material from the demolition of an old factory, and this material was subsequently reused at the same site”.

NEWS & REPORTS Once again ,MB Crusher Buckets and products have become important assets in worldwide events. Back in 2010, MB Crusher Buckets were used to build the Soccer City Stadium ahead of the South African World Cup. After South Africa came Brazil and its Arena Pernambuco, the construction of which was entrusted to the national giant “Construtora Norberto Odebrecht”. It was Odebrecht to contact Grupo Monte Sinai for the hire of its MB Crusher Buckets. Significant investment in research has allowed the Vicenza-based company, world leader of its sector, to produce indispensable and cutting-edge buckets with unparalleled performance. It is precisely for this reason that MB products are chosen by companies from across the globe who are working on projects on an international scale. These projects confirm the enormous flexibility of the MB Buckets, which have become ruler of this market in just a few years These customers confirm the versatility of MB products.

“With the MB Crusher Bucket - Mr De Souza of Brazil said - the great advantage has been that of saving on the cost of material: instead of buying it from third parties, we used material that came straight from the site, from the demolished construction or from the site ground itself. This has allowed us to make significant savings in terms of material, resources, our time and the time of the customer who commissioned the work. This show of “significant savings” has led to other commissions at the same sites as well as conveying a sense of solid professionalism to our customers. It is worth mentioning that we use the MB Crusher Bucket for an average of 10 hours a day, 6 days a week. On top of all this, no special maintenance is required, keeping costs low compared to mobile or fixed crushers”. MB Managing Director, Guido Azzolin concluded: “In periods of global economic downturn such as the one we are currently facing, the use of our machine for large events shows that companies who invest in research and technology and offer cutting-edge products will always find a place on the market and gain prominent positions in prestigious sectors such as that of large-scale construction”.

IAA Commercial Vehicles : ContiTech Achieves Quantum Leaps in Truck Development

ContiTech AG

• Air springs with plastic pistons save weight and increase ride comfort • Components promoting more safety, comfort and environmental friendliness

Hanover, 2012. Truck manufacturers want to offer their customers even more driving dynamics, safety and comfort, while also lowering consumption, emissions and operating costs. An important contribution to this has been made by the ContiTech products developed in response to the demands of current and future commercial vehicles. These would be showcased from September 20 to 27 at the 64th International Motor Show (IAA) in Hanover .

Safety for drivers Ride comfort plays a decisive role in ensuring that drivers who are relaxed are safer than other drivers. A new development from ContiTech has achieved a quantum leap in this area, with the Air Spring Systems business unit now successfully mass-producing truck air springs with an innovative plastic piston. Its interior volume is utilized to the full to enhance comfort. Up to 75% of the weight of conventional steel pistons is saved thanks to a special type of plastic and a new simulation method, cutting the weight by up to 12 kg per axle. The breakthrough came when the advantages of improved material technology with a completely new type of simulation method cleared the way for a product innovation. The robust and eco-friendly interior trim material from Benecke-Kaliko comes into play here in the driver‘s cab interior. ContiTech develops and produces decorative surfaces for instrument panels, sun visors, glove compartment doors, door and side trims, seating and center consoles. This includes the innovative surface material Acella® Eco natural that is made from up to 40 percent renewable raw materials, which in comparison to standard cover material has a 14 percent improved Heatable high-performance hoses: ContiTech expertise makes the SCR technology winter-proof.

Another new development is the DecoJectTM thin foil for enhancing unpainted injection molded parts, an alternative – which is just as inexpensive as it is attractive – to lacquered injection molded parts, TEPEO 2® compact sheeting with anti-scratch surfaces and weight optimized Yorn® surface material. But it is not only materials from Benecke-Kaliko that enhance the driver‘s cab: The air springs for the driver‘s seat are also ContiTech products, as are the sleeve air springs for supporting the cab itself.

special EPDM rubber mix, it reduces fuel consumption and CO2 emissions. The highly flexible CONTI® UNIPOWER ECO2-FLEX can reduce the power loss in the ancillary equipment drive, thereby also further reducing fuel consumption and carbon dioxide emissions. With its textile surface, the CONTI® UNIPOWER TOUGH GRIP ensures smooth running under extreme conditions. There is another reason why belts help to protect the environment: The CONTI® UNIPOWER ELASTIC renders clamping systems superfluous, which results in a more compact design and reduces weight.

Hose lines for lower emissions

ContiTech offers numerous other innovative systems that are finding their way into more and more trucks, including air springs and air spring damper modules for front axles and engine mounts to dampen vibrations. With forwardlooking technologies, ContiTech makes commercial vehicles safer, more economical and more eco-friendly.

In addition to the air springs, ContiTech also offers numerous other components for modern trucks. The Fluid Technology business unit is particularly active here. The SCR hose line systems are particularly interesting. SCR stands for “Selective Catalytic Reduction”, a technology that removes nitrogen oxides from diesel exhaust gases. In the catalytic converter, harmful nitrogen oxides (NOx) are converted into harmless water vapor and natural nitrogen by means of a urea solution. Developed specifically for the SCR method, ContiTech‘s high-performance hoses ensure that the solution does not freeze and can be safely transported from the tank to the catalytic converter at any temperature. ContiTech Fluid Technology’s product range for trucks includes innovative fuel lines with high temperature and pressure resistance, power steering hose lines for weight and noise reduction, hydraulic plugin systems, aluminum A/C lines, form-bent plastic A/C lines, charge air hoses for EURO 6 applications and cooling hoses for extreme operating conditions.

IAA 2012 in Hanover

A new panther semitrailer with 2+6 axles

t the International Motor Show Commercial Vehicles in Hanover, which took place in September 2012, we presented another highlight of our panther trailer range.

A new panther semitrailer with 2+6 axles

• Own steering circuit of the 2-axle dolly: The axles can be steered in the opposite direction to the 6-axle rear chassis. The dolly axles follow the track of the tractor unit.

The 8-axle trailer with a payload of 95 t was presented as a single extendable version. We would like to put your attention on the following key features:

• Optimized centre of gravity: The extension of the lowbed is positioned after the first two axles. Consequently, these 2 axles create a dolly which supports the fifth wheel load of the tractor unit (see annex S8E).

• Dolly with a superior stroke of the suspension of 380 mm: Driving over crests and through sinks becomes much easier. In difficult situations, the neck can be raised and lowered manually in order to improve the clearance. The total stroke is 1.300 mm (+600 mm / -700 mm).

• Real loading height of 850 mm (-70 mm/ + 245 mm): Our lowest possible driving height is 780 mm, 10 mm lower than that of our market companion. As a consequence, these multi-axle panther trailers are a real alternative to big low loader combinations or even modular trailers.

• Less payload loss: The compensating neck features a hydraulic adjustment of the fifth wheel load (23 t / 18 t). Additionally, two more adjustments of the fifth wheel load can be set mechanically (21 t / 16 t) and (17,5 t / 13,5 t). Due to the balanced weight distribution between the truck and the trailer axles this feature enables the operator to optimize the use of the respective tractor unit without loosing payload.

• Increased total loading length: At the interface between the dolly and the rear chassis, a compression joint is integrated; by hooking in an extra beam the loading length can be increased by 9 metres.

• Optimized turning radius and minimal tyre wear and tear: Rhe 6-axle rear chassis comes with the world’s first frictionsteered double wishbone axle. So far, such a solution is not available for a swivel axle.

• Lowbed designed for high lumped loads as well as machine transports: The maximum payload can be placed in on 4 m length in the centre of gravity. • Better load distribution: Due to an improved centre distance of 1.500 mm there are advantages especially for crossing sensitive bridges. Customers confirm that this wheel base offers advantages for getting a single trip permit. The modular trailer range of DOLL offers alternative wheel bases of 1.360 mm and 1.810 mm. • High degree of serviceability: The access to hydraulic emergency functions and electrical junction boxes has been improved through design changes.

This panther trailer and the different other vehicles of the panther series offer a lot of technical advantages and can be used in very different industries. The flexibility and the variety of the panther trailers guarantee their economic efficiency. The trailer market has realised the potential of the double wishbone suspension. Other trailer manufacturers have adopted design elements of our solution. Nevertheless, there are huge differences between the individual solutions of the manufacturers, some of which have a negative

impact on wear and tear of tyres, durability and security. With more than two and a half years of panther serial production, DOLL is the leading company in this double wishbone technology. At the international motor show for commercial vehicles (IAA) you had the chance to have a detailed look at the DOLL panther technology and the different other solutions on the market. The ORIGINAL doesn´t need to fear that comparison!

Road milling: Betek W6AOCL-R is biting through asphalt

and gnarling its teeth to costs

Betek Research and Development together with Product Management and users especially are pleased with a new milestone in bit development: The Betek round shank cutter bit W6AOCL-R not only bites through fine and surface layers of asphalt, it is also gnarling its teeth at costs. The key tool of a milling machine is the milling drum rotating against the direction of feed. Tool holders are mounted on the drum bodies for the rotating round shank cutter bit. During the milling process, the bits loosen the surface and granulate the surface to a re-usable material of small pieces. The W6AOCL-R is able to show its strengths especially when milling great cut depths in the surface with a large number of bits on the drum. It is the extensive tungsten carbide tip with the long, cylindrical cutting edge in particular that ensures the machinery runs smoothly with a high performance in terms of machine feed over the complete bit service life. The new bit also performs excellently when milling asphalt on the top layer, where tungsten carbide wear tends to be the key criterion for wear and the long, slim tips ensure a high degree of effectiveness. In various tests carried out in Europe and the USA, the W6AOCL-R was far superior to comparable competitors products. It is the rotation characteristics that the superior R-technology of the Wirtgen products bring to the fore. Perfect rotation characteristics for the round shank cutter bit are the prerequisites for optimum usage of the tungsten carbide tip and the complete bit. This in turn leads to exceptional benefit for the customers.

With the Betek W6AOCL-R bit, users reduce costs by 2.5x dependent on the site condition: the wear-optimised bit guarantees an extremely long service life and reduces costs considerably.

If the calculation takes into account the considerably higher costs – due to the frequent interruption to the milling process caused by having to change a competitor products bits – the cost-effectiveness of the W6AOCL-R increases many times over. Its not without reason that many customers have changed to the new Betek product.

The W6AOCL-R is able to show its strengths especially when milling great cut depths in the surface with a large number of bits on the drum. This new development also offers major benefits in surface layer work.

This new bit offers the customer considerable costsaving potential. Bit costs of € 0.28 / m³ arise when using the Betek W6AOCL-R; when using competitors products they rise to € 0.71 / m³! Competitor products incur 2.5x more costs with reduced productivity!

Road milling, Surface mining, Stabilising: Betek and Wirtgen have a solution for every task

Whether road milling, stabilising or surface mining: Betek and Wirtgen have one major goal together – the continuous development of these technologies to be able to offer customers the greatest possible efficiency. Betek is proud of the system partnership with Wirtgen that has been a success story for over 30 years. Product Manager Thomas Allgaier is responsible for the product group of bits used for road milling, stabilising and surface mining. Thomas Allgaier: „The performance of bits is being continually enhanced thanks to innovative power and application-specific developments. The product range offers the ideal solution to each user, even for the toughest of milling jobs.“ The most recent example is a stabilisation project in exceptionally difficult conditions in Denmark. The ground had to be stabilised for the rebuilding of the A 7 motorway. The milling machine had to overcome clay soil that was interspersed with stones of varying sizes. The milling process tested all implemented standard holders and bits to their limits, which lead to numerous bit breaks and holder faults. ”This is the nightmare of every machine supervisor and we were called to help,“ explains Thomas Allgaier, who together with his Wirtgen colleagues Bjarne Dahl and Morten Wold from Denmark and Thomas Lehnert and Helgo Koch from Wirtgen in Germany squared up to this challenge and modified holders and bits specifically to the local conditions in situ. Allgaier: ”It was brilliant to introduce the new Betek bits on site and witness the results together with my Wirtgen colleagues. There were no breakages, productivity was stellar and the wear protection excellent.“ The road construction company, which was able to successfully complete the project with this support, was more than happy about the speedy and uncomplicated approach. Product

The Wirtgen tractor-towed stabilizers are attached to a traction vehicle – in this case a tractor. In Denmark, the stabilizers transformed the clay subsoil littered with large stones into a workable and compressible surface. Material that was too coarse was broken down in the milling drums mixing chamber.

Manager Thomas Allgaier is naturally just as satisfied and stresses, ”This would not have been achievable by myself. There is always a team behind you. My colleagues Christoph Haberstroh and Sarah Bitzer have as much of a hand in this success as our system partner Wirtgen.“

W1-15/25RK: This is the designation for the Betek bit / holder solution for the difficult subsoil found during the construction of the A 7 in Denmark.

FMG intensifies strategic partnership with Wirtgen In recent years, the surface miner fleet of the Fortescue Metals Group (FMG), one of Australia’s largest iron ore producers, has grown to a total of 43 machines, with 28 Wirtgen 4200 SM and 15 Wirtgen 2500 SM, which ensure the selective, economical extraction of high-quality iron ore in the Pilbara region. “The Wirtgen Surface Miners enable us to separate the ore from the excavated material. The majority of the ore stock could not have been extracted using conventional means, making the surface miners decisively important to our success,” explains Cody Faryna, FMG Surface Mining Manager Christmas Creek mine site. The Wirtgen Surface Miners cut, crush and load the material in a single step, thus providing enormous potential savings. For example, they lower production costs by some 40 percent per ton of iron ore, and the investment costs are around 50 percent lower than for conventional mining methods.

A Wirtgen 4200 SM produces up to 3800 tons of iron ore per hour, depending on the hardness. The cutting depth is up to 650 mm in hard rock and the cutting width 4200 mm.

Issue 03 | 2012

Synergy effects increase cost-effectiveness and machine availability The good partnership between FMG and Wirtgen forms the basis for a constant continuing development of the technologies. In the 4200 SM, FMG and Wirtgen have developed a surface miner that is even more powerful and ideally adapted to the mining conditions for iron ore, and which has been successfully proven since 2009. “Support for our machines is a continuous development strategy between Wirtgen and Fortescue. In order to maintain a constant product volume, we have to concentrate on a highly reliable fleet. And Wirtgen plays a major role in the development and improvement of all components,” says Faryna, discussing the challenges involved.



Innovations in cutting technology pay off Everyday practical experience is used in the ongoing development of the surface miners – especially in cutting technology, one of Wirtgen’s core competencies. With the HT15 quick-change toolholder system, the innovation leader has developed a unique device which simplifies the process of changing toolholders and shortens it by 60 percent. Together with the new WPI (Wirtgen Pick Inspection) tool wear detection system, which ensures maximum use of the cutting tool capacity, the latest innovations have led to significant production increases at FMG.

Expanding proven service structures with new concepts Especially in mining, where the machines are in use every day, 24 hours a day, machine availability is a central factor for success. In addition to surface mining technology, Wirtgen also presents itself as a reliable partner with a comprehensive service offering. The service products are the result of an intensive collaboration between the main Wirtgen plant in Germany and its subsidiary Wirtgen Australia in Perth. The regular communication with and

physical proximity to the customer ensure fast reaction times. New demands, process changes or machine developments can thus be quickly implemented – both directly on site in the mine and in the plant, as Hedley Quick, FMG Superintendent Surface Miners Cloudbreak mine site, confirms: “Wirtgen incorporates our ideas and practical experience into the further development of the machines. What is more, they offer a service that meets our very high demands and requirements. It is unique in the mine. Wirtgen takes care of everything we need.” In the middle of 2012, a general overhaul of the surface miners in Perth was added as a new product in the Wirtgen Group’s service program. With the strategic change to a proactive maintenance system, both partners are setting the course for the future, as the growing surface miner fleet means increased maintenance. The general overhaul sets the pace for an optimized and far-sighted maintenance strategy.


NEWS & REPORTS Mining in Australia – Wirtgen invests in personnel and infrastructurer “In order to further strengthen our position as a reliable mining partner in Australia, we have made enormous investments in technical personnel, administrative systems and the infrastructure – in the mine as well as at the branch office. On a site of 4.7 hectares, we are also constructing a factory and warehouse building specially equipped for surface miners, in which we can carry out general overhauls or retrofits of components, as well as training on service and work procedures,” says Paul Hockridge, General Manager Mineral Technologies Wirtgen Australia, describing the investments to expand the Wirtgen Group service structure in Australia.

743 kW of concentrated power drives the type 2500 SM Wirtgen Surface Miner, which produces some 800 tons of bauxite per hour.

Brazil: Surface Mining

the primary extraction process for bauxite production In the northern region of Brazil, in the city of Paragominas, in the state of Pará, a Wirtgen type 2500 SM Surface Miner is revolutionizing bauxite production. The machine, the first of its type in Brazil, has been in operation there since March 2011. The “Mineração Paragominas” mine is 64.6 percent owned by the aluminum producer Hydro, with the Brazilian company Vale owning the remaining 35.4 percent of shares.

The 2500 SM from Wirtgen: Economy and efficiency With a cutting width of 2500 mm and a cutting depth of up to 600 mm, the Wirtgen Surface Miner can produce some 800 tons of bauxite per hour. The 100-ton machine runs on more than 1000 hp. The 11-meter discharge conveyor transfers the material directly to the dump truck – with no other mining equipment, such as excavators or wheel loaders, required. “The 2500 SM produces as much as two or three conventional mining sets,” explains Cláudio Morgado, Maintenance Manager at Mineração Paragominas. “That not only lowers production costs but also makes working in the mine safer.”

Surface mining: sound environmental practice and sustainability In surface mining, mineral raw materials are recovered with no drilling or explosives – a special cutting roller cuts and crushes the rock before it is loaded by robust conveyor systems into the dump truck. Surface miners thus save not only time and money, but also energy. In

Issue 03 | 2012

addition, the material extraction is also vibration-free. The low noise and dust development in surface mining mean a further advantage over conventional methods. “Naturally we want our work to be profitable, but our corporate goals also include bringing good business together with sound environmental practice and sustainability. We can achieve exactly that with the Wirtgen Surface Miners,” says Agnus Delagado, General Manager Mining at Mineração Paragominas, regarding the advantages of the surface mining method.

Wirtgen Group: Customized service solutions The remote location in the Amazon region and the 24-hour use of the machine demand a seamless local service infrastructure. For that reason the local Wirtgen Group dealer Deltamaq operates a service support center directly in the mine. Service technicians, warehouse specialists and applications experts are constantly at work ensuring smooth equipment operation. All service technicians receive regular training at Wirtgen’s main plant in Germany.


NEWS & REPORTS One of the most important features of the Wirtgen Surface Miner is its ability to load the cut material directly onto the truck. The 2500 SM is a rear loader. The belt can be swung 90° to either side and the discharge height is adjustable.

Working to expand capacity Convinced both by the Wirtgen Group’s customer service concept and the surface miner’s performance, the mine operators have decided to add two more type 2500 SM Wirtgen Surface Miners in Paragominas. Since the middle of 2012, a total of three Wirtgen Surface Miners have been in use for Mineração Paragominas. Surface mining is thus completely replacing the previous conventional extraction methods.

The use of WPI provides the machine operator with a quick and easy overview of cutting tool wear – without causing any machine downtime.

Wirtgen Pick Inspection (WPI):

The clever and intelligent Surface Miner Premiere: Wirtgen is introducing the Surface Miner with integrated measurement system to detect wear and tear on cutting tools. The 4200 SM WPI is thus not only cost-effective, it also saves valuable resources. WPI stands for Wirtgen Pick Inspection – and essentially consists of eight very quickly measuring sensors integrated in the cutting roller housing. These sensors are used to measure the wear of the cutter. WPI can take measurements in less than one minute and this can be carried out easily during truck changeover so that downtimes can be avoided. WPI is very easy to operate: the entire measurements are taken automatically at the press of a button, and the operator can see the measurement results on a separate screen. Machine operators and service technicians are thus able to optimally plan any necessary service intervals, and the cutting tools are used to their maximum capacity. This makes work much easier

4200 SM WPI: Maximum performance in large-scale opencast mining The new 4200 SM is a high-performance machine for mine operators and customers in large-scale opencast mining whose goal is to achieve an annual mining capacity in soft rock of up to 12 million tons with a single machine while wanting to make full use of the benefits offered by


NEWS & REPORTS Wirtgen’s selective mining technology that enables cutting, crushing and loading in a single working pass. The surface miner is available to customers in two different designs: as a powerful mining expert for hard rock, such as iron ore, bauxite or phosphate, or for use in various types of soft rock including, for example, coal or lignite. The miner has a cutting width of 4.20 m and is capable of working at a maximum cutting depth of 83 cm in soft rock. The heavy-duty machine is equipped with a 16-cylinder diesel engine from Cummins, making it the ideal candidate for a wide range of applications as its power of 1,194 kW / 1,623 PS offers tremendous reserve capacity. Being the most powerful machine in the surface miner division, the 4200 SM complements Wirtgen’s product portfolio in the upper performance class. Generously dimensioned tanks offering capacities of 2,900 l for diesel and 10,000 l for water additionally increase the miner’s uptime. A two-stage conveyor system with 1,800 mm wide primary and discharge conveyors and a discharge conveyor length of 12,000 mm or 16,000 mm respectively, supports the miner’s impressive cutting performance of up to 3,000 tons per hour. The discharge conveyor’s large slewing angle of 180 degrees, flexible height adjustment and variable belt speed ensure smooth loading of large transport trucks even in space-restricted conditions.

App for service teams reduces changeover times Another advantage of WPI comes from the simplified workflow for the service teams responsible for changing the cutting tools. If a cutter needs to be changed, a separate mobile end device prepares the information stating which cutter is to be changed. This function is accomplished by an application that shows part of the cutting roller and marks the cutter to be changed in color. In addition, when operating the entire surface miner fleet, the information on the wear status of the cutting tools helps to optimize the whole service and production process. For example, the use of service technicians and the provision of spare parts is planned specifically based on the wear information of the individual machines.

Crushing iron ore:

Mobile Kleemann equipment combination used in Australia The Australian continent is rich in mineral resources, and the immense growth in the demand for steel has put iron ore extraction into high gear. Iron ore is mined either by surface miners, which cut the deposits from the surface layer by layer, or using the drill and blast method.

New mining project with the Kimberley Metals Group The Kimberley Metals Group (KMG) launched the “Ridges Iron Ore Project,” a new mine in the Kimberley region of Western Australia, in 2011. Here the iron ore is extracted from a mountain ridge, taken by dump truck to a central location and processed. The processing itself is handled by SJ Crushing as a subcontractor of KMG. “The major challenge for us was going very quickly from submitting our bid to a stable production of 500 tons per hour,” says Neil Fitzpatrick, Project Manager at SJ Crushing, describing the project requirements.

Mobile combination of four Kleemann machines SJ Crushing found its solution with Kleemann. “The director and owner of SJ Crushing, Steve Crabbe, saw clearly that he needed a decisive advantage in order to be awarded the contract. And he found that advantage in equipment from Kleemann, with its robust design and its

diesel-electric power concept,” continues Neil Fitzpatrick. Crabbe became aware of Kleemann at bauma 2007 and made contact when the call for tenders was issued for the project. The mobile solution, consisting of a MOBICAT MC 125 Z mobile jaw crusher and three MOBICONE MCO 13 S secondary crushers was developed in close cooperation with the Kleemann experts from Germany. Because the initially anticipated project duration was very short, just four years, it quickly became clear that the solution would have to be a mobile one. The equipment in the mine is also quickly movable in case of changing conditions or requirements.

Starting sizes of up to 1000 mm edge length, end product 0-10 mm The cut or blasted material is transferred to the MOBICAT MC 125 Z by wheel loader. The size of the material recovered by the surface miners ranges from 0-200 mm, while the blasted material can have edges up to 1000 mm long. In addition, the compressive strength of the material can be far above 300 MPa. The mobile cone crushers break the material down to a final grain size of 0-10 mm, each of the

Best after-sales service of top importance The machines run in two shifts around the clock, seven days a week, so excellent after-sales service is extremely important. According to Neil Fitzpatrick, “the reliable support from Wirtgen Australia was a major deciding factor.” And the Australian Wirtgen Group subsidiary is optimally positioned to meet this requirement, taking care of major clients who run the numerous surface miners in 24-hour operation in this region.

allmineral opens office in Perth/Western Australia With the most recent incorporation of allmineral Australia Pty Ltd allmineral directly contributes to the remarkable expansion of Western Australia’s iron ore mining industry. This direct investment provides for an even stronger market presence of allmineral in Western Australia concurrent with further improved customer services now directly rendered from allmineral’s Australian experts. At the same time it demonstrates its high appreciation of existing and future Australian customers in supporting them in a highly competitive market. There is an increasing demand for allmineral’s modern processing technologies being capable of turning low grade ore from the Pilbara area into high-quality products. After the successful and strategically important installation of Rio Tinto’s pilot plant containing allmineral’s core processing equipment types alljig®, allflux® and gaustec® WHIMS, allmineral continues its success: in 2011, allmineral secured contracts for another 12 jigs type alljig® as well as 14 fluidized bed separators type allflux® for the Pilbara. In the course of 2012 17 alljig® and 25 allflux® will be in operation in Australia finally. Beyond doubt above mentioned new equipment will significantly empower allmineral’s position in a booming Australian market. Annual capacities are estimated to

Issue 03 | 2012

increase by another 300 million tons over the next few years. This scenario requires perfect logistics and allmineral’s superior processing technology at the same time – a technology Australia’s big players already rely on. 14 fluidized bed separators type allflux® and 12 wet jigs type alljig® are currently being installed for the efficient beneficiation of iron ore. Manufactured and pre-assembled in Western Europe, they undergo tough factory tests prior to being shipped to Australia. Currently allmineral’s workshops are crowded with machines – most of them ready to leave for the Pilbara – while allmineral’s experts are completing the final testing. The throughput rates of the allflux® fluidized bed separator are 180 respectively 250 tons of iron ore per hour. The material (particle size <1mm) is separated in two stages based on particle size and density. The flow



and control equipment facilitates the generation of three highly selectively graded products from a single machine, including thickening and desliming. The air- and side-pulsed alljig®-F-2500 jigging machines utilize the density differences between the iron and the lighter minerals in the ore for efficient separation. Due to the fact the jigging machines can be flexibly adjusted, they are able to precisely separate ores from one millimeter up to 8 millimeters. The alljig®-F-2500 operates physically stable at a throughput rate of 120 tons of iron ore per hour with minimal energy consumption. The entire capacity of the new allmineral processing equipment in the Pilbara region is thus approximately 4,500 tons per hour, i.e. around 30 million tons per year. Overall, allmineral has installed 17 alljig® machines, 25 allflux® machines and 1 gaustec® high intensity magnetic separator in Australia so far.

Screening, stabilizing and producing fluidized soils The 3-mtbc starscreen from the company Backers practically covers the whole range of screening and mixing technology. It screens bulk solids, soils and biomass etc into 3 fractions and a fourth fraction can also be achieved using the grid. Because it is screened roughly at first, the rate is hugely increased and the medium grain is cleaned very well. The machine is operated in „organic material“ by at least one wheel loader, in „mineral material“ the starscreen bunker is usually filled by a digger and the screened material is transported away with a wheel loader.

Due to the precise dosage of the binding agent, the amount added can often be reduced. The control unit with printer for tsoil stabilization and production of fluidized soil is inserted in the right control box.

Thanks to the combined wheelcaterpillar design the material can also be put into a stack. In the 3-mtbc version, the mobile screening machine can also be used as a starscreen and mixing unit. When used as a starscreen and mixing unit, the material is also roughly screened first to remove the biggest pieces and loosen the fractions and to evenly distribute them.

Along with the postive influence on the cost factor, the environment can also be protected. One important aspect is also that the working process is largely carried out free of dust. To produce fluidized soils, the starscreen and mixing unit can add water in doses. The water is usually added to the mixing solids in a mobile mixer. The final mix is produced in the mobile mixer which drives the â&#x20AC;&#x17E;fluidized soilâ&#x20AC;&#x153; product in batches to the place of use. The batches can be documented thanks to the integrated voucher printer. If the starscreen and mixing unit are provided with their own agitator, there is also the possibility of mixing and filling the fluidized soils directly at the place of use. Alongside soil stabilization and production of fluidized soil, other materials such as ash and similar materials can be mixed with soil by the starscreen 3-mtbc. The areas of use for the starscreen 3-mtbc are more multifaceted than a Swiss Army knife. Instead of the chalk container or the fine, second screen cover, an extended discharge belt can also be used. Ships, rail wagons, trucks and large dumpers etc can be loaded with the extended discharge belt. The weight of the load can also be documented in this case.

Backers pipeline padder Backers Maschinenbau GmbH is a German company and manufactures 2- and 3- fraction starscreens. An advantage of the Backers starscreens is that they can screen wet material with a fine screening size. This is important when there are worse conditions regarding weather or material for example with loamy soil. The Backers pipeline padder is the starscreen 2-ta which is build on tracks and it screens into 2 fractions. The fine material, which is padding the pipe, gets out sidewise of the machine. So the Backers pipeline padder can drive along the ditch of the pipe. Also it’s possible for the pipeline padder to screen at hilly terrains up to 10 degree. The capacity of the pipeline padder depends on the material, screening size, terrain etc. At 20 mm screening the capacity can be up to 200 tons per hour, at 15 mm it’s up to 150 tons per hour. The finest size which the Backers starscreen can screen is 5 mm. On top of the hopper can be a grizzly mounted. It covers the starscreen against bigger stones and other oversizes. The starscreen 2-ta can be used for pipeline padding but also to screen other mineralical material like building rubble or organical material like compost, wood chips etc.

Backers Maschinenbau GmbH The starscreen technology of the Backers Maschinenbau GmbH has been successfully employed over 20 years of production. Continually new demands develop in the market, but flexibly-designed, future-oriented company policies have allowed the Backers Company to steadily grow. This was supported by great trust and superior, longterm cooperation with clients, importers, employees, and suppliers. So, the Backers screen technology of today is not simply bought. No, it lives with the intensive cooperation of the above-mentioned participants and the growing demands in the form of innovation, trust, loyalty, and quality. And so the most important guiding principle of Backers Maschinenbau GmbH and its partners is: Quality is when the customer returns, not the product!

ContiTech: Two New Bearings for Wind Power Stations

ContiTech AG

Generator bearing and gearbox bearing • Increasing the durability of the components • Series of measurements form the basis for customized new developments Hanover, 2012. In a single go, ContiTech Vibration Control has further developed its bearings for modern wind power stations in the run-up to Husum WindEnergy (September 18 to 22, 2012) by developing two innovations. An innovative generator bearing and an optimized gearbox bearing can help to increase the service life of all components in the drivetrain in the long term. „Particularly in large plants of 5 megawatts and more, the dynamic loads that arise during operation can place a very heavy load on the different components,“ declares Vincent Sambo, Sector Manager for Wind Power at ContiTech Vibration Control. „For this reason, an optimum bearing is of special importance for modern drive technology.“ Bearing elements from ContiTech Vibration Control take on the job of load bearing as well as impact and vibration insulation. In developing these innovations, ContiTech draws on decades of experience in the development of elastic bearings and controlled process manufacturing of mounting components for industrial applications.

New developments for smooth running As the life-giving force in the wind power station, the drivetrain is exposed to particularly extreme loads. To ensure smooth operation of the wind power stations, it is important to align the rotor, gearbox and generator with each other exactly. Any horizontal or vertical skewing places a higher burden on the drivetrains and machine carriers components, and this in turn shortens the systems service life. ContiTech has developed a generator bearing with additional functions so that the generator can be aligned correctly during assembly. This bearing can be moved both vertically as well as horizontally. Thanks to this adjustability, the location of the entire drivetrain can be set exactly, and this, in turn, means that the load can be reduced to a minimum.

In the run-up to Husum WindEnergy 2012, ContiTech Vibration Control is presenting new solutions for the drive bearing in wind power stations.

Issue 03 | 2012


NEWS & REPORTS The innovative generator bearing and the optimized gearbox bearing lengthen the service life of all components in the drivetrain.

„In order to record the structure-borne noise, for example, we apply a large number of acceleration sensors to the drivetrain. Recording of the time data from a total of 95 measuring channels is performed online by a multichannel measurement system. This allows us to analyze the data and produce an exact simulation later offline,“ says Peter Eckwerth, Head of Advanced Development at ContiTech Vibration Control, explaining the process.

ContiTech Vibration Control is also implementing a new development for the gearboxs bearing. Half shells are normally used for this job. Two of them form a cylindrical bushing, which is pre-tensioned radially. In conventional elements, irregularities due to the geometry arise in the load to which the rubber pad is exposed. This means that optimum bearing of the gearbox cannot be guaranteed at present. It is for this reason that ContiTech optimized the half shells rubber pad. The two half shells fit into each other perfectly, and this ensures an even load distribution within the cylindrical bushing. The bearing element with the improved rubber contour achieves a service life that is up to five times longer than that of conventional bearing elements.

Exact measurements for innovative new developments These developments from ContiTech were preceded by comprehensive series of measurements and simulations in which the loads to which the drivetrain is exposed were analyzed. „These processes provide us with decisive operating data so that we can create the ideal design for the drivetrain in terms of vibrations,“ says Vincent Sambo. „These processes form the basis for development of customized components for wind power stations, thereby further enhancing their performance.“ The tests focus on the amplitude and frequency of acceleration on the drivetrain, the low-frequency movements of the components, the isolating performance of the elastic bearings and the natural frequencies of the drivetrain.

In various short-term measurements, the experts at ContiTech Vibration Control examine the vibration behavior while the network supply is at constant operation, as well as while the wind turbine is starting up and at a standstill. In this way, the various loads to which wind power stations are exposed are recorded accurately. The exact design of the drivetrains components is created on the basis of these comprehensive analyses. Working together with the manufacturers, ContiTech thus succeeds in developing optimized elastomer components that deliver maximum service life, and in putting these components into service.

Doosan Launches New DL200-3 Wheel Loader


aterloo, Belgium. At Intermat, Doosan Infracore Construction Equipment launched the new generation DL200-3 wheel loader, which combines high engine power with a number of new features to minimise fuel consumption and provide exceptional performance, ease of handling, significantly enhanced operator comfort, serviceability and durability. The DL200-3 is powered by the Doosan DL06 â&#x20AC;&#x2DC;common railâ&#x20AC;&#x2122; 6-cylinder turbocharged diesel engine meeting Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. With a bucket capacity of 2 m3, the DL200-3 wheel loader is intended to meet a wide range of material-handling needs from loading and transporting granular material (such as sand and gravel) to industrial, mining and quarrying applications. .

High Operator Comfort The DL200-3 wheel loader features a new cab design, with several improvements both inside and outside. The cab offers better visibility through a wider front glass section and an extended wiper blade area.

By relocating the reservoir for the wiper water to the outside of the cab, space inside has been increased, providing more foot room. The air conditioning system is regulated automatically by a temperature sensor.

A new instrument panel has an integrated vehicle control unit (VCU). The control panel has been redesigned for more convenience, allowing the operator to choose the information they would like to have displayed. Using the Main Menu, the operator has access to several functions and machine information. Data such as pressure, temperature and engine speed can be monitored in real time. Furthermore, operator and service staff are able to get detailed information via the Special Menu.

To keep cans and food fresh, a new cooling compartment is standard. There is also more storage room behind the seat.

The new generation wheel loaders will have Grammer seats, which are vertically as well as horizontally air suspended. This design, which cushions movements to the front and the rear, is recommended by orthopedic consultants and is well accepted by operators.

Issue 03 | 2012

Access to the cab is made easier by an improved hand rail and steps. The width and length of the mud guards have been increased to provide cleaner access to the cab.

Lower Fuel Consumption Three engine working modes - ECO, NORMAL and POWER - ensure optimum fuel consumption for different applications.


NEWS & REPORTS With the ‘Power-Up’ function, the operator can manually adjust to the next highest working mode by applying a full stroke of the accelerator pedal. With this function, the operator can travel in NORMAL mode and switch to POWER mode when it is really needed, such as when taking material from a pile. The ECO Bar provides information about fuel consumption in relation to machine performance in realtime, allowing the operator to select the driving profile for the best fuel efficiency. The operator can set a password for machine start. If Auto Idle is activated, engine speed goes down about 200 rpm after 10 seconds if there is no machine movement. Auto Idle is ideal for applications with longer waiting times, such as truck loading. Thanks to Auto Idle, fuel consumption is reduced by up to 8%.

Improved Hydraulics and Differential Axles Like all Doosan new generation wheel loaders, the DL200-3 is equipped with load sensing controlled, variable hydraulic piston pumps, improving performance and reducing fuel consumption. With load sensing, the hydraulic pumps receive a signal from the MCV informing how much oil is needed. This helps to save on engine performance. With the clutch cut-off system engaged, the driver is able to disconnect the transmission from the engine by operating the brake pedal, to have 100% engine performance for the hydraulic system. As a result, movements are faster, breakout force is maximized and fuel consumption is reduced. The new ZF limited slip Type II differential axles provide more durability and a longer lifetime. Rolling resistance for the axles is reduced, improving traction and decreasing fuel consumption. As an option, customers can choose ZF axles with a hydraulic differential lock. This function is engaged via the operator pedal or in automatic mode, depending on the torque resistance in 1st and 2nd gear. The advantage of the hydraulic lock system is that it has less rolling resistance compared to the limited slip system. The radiator fan is hydraulically driven and controlled by an ECU. Changing the fan direction for cleaning the radiator can be done manually from the cab without having to switch off the engine. Fan reverse intervals (30 minutes to 2 hours) can be set via the menu.

Issue 03 | 2012

Durability and Serviceability The lift arm has been strengthened with 10% thicker metal in the arm and in the tilt lever. An automatic front control system allows the operator to save one low and one high position. The boom raise “kick out” function reduces cycle times. “Return to dig” positions can also be saved. New kinematics and a larger cylinder on the lift arm have allowed the main pressure in the front hydraulic system to be increased, with a corresponding increase in breakout and lifting forces. The DL200-3 offers as an option the SKF Vogel Auto Lubrication system. This improves the lifetime of the machine and increases operational hours for better productivity. A larger opening angle for the side door improves serviceability. Swing out side doors provide easy access to the rear for cleaning the new one block radiator. Increased space in the engine compartment ensures that components such as filters, valves and batteries are within easy reach for service work. The operator can set and monitor the time remaining to the next service. If the maintenance period is exceeded, a pop-up warning will appear. As well as offering more standard features than other machines of its size on the market, there is an expanded choice of options for the DL200-3 wheel loader, including electric steering.

CeMAT intralogistics exhibition switches to new two-year cycle CeMAT 2014 (19 to 23 May)

Hanover, Germany. Beginning in 2014, the Hannover-based CeMAT exhibition will be staged every two years. This change was made by the show’s organizers at Deutsche Messe to accommodate the faster pace of change in the intralogistics market as well as the industry’s shorter innovation cycles. The decision to present the leading intralogistics exhibition every two years was made in close consultation with the CeMAT Executive Committee and the German Engineering Federation (VDMA) as well as at the unanimous request of exhibitors. “In today’s competitive global market, intralogistics companies need to be international players if they want to grow. So it has become all the more important for them to showcase themselves at this globally leading trade fair at shorter intervals than before,” commented Dr. Christoph Beumer, Chairman of the CeMAT Steering Committee and Managing Director of BEUMER Group GmbH & Co. KG. “Given the rapid pace of technological development and the resulting market dynamics, the new biennial cycle at CeMAT will further strengthen our industry and add new momentum.” “The intralogistics industry is extremely innovative and has a strong global outlook. It needs a world-class B2B platform that is held every two years – one which is fully geared to the market and to worldwide demand. This is precisely what CeMAT offers. The new biennial cycle combined with the show’s new keynote themes and extended theme line-up will further enhance the value CeMAT delivers to the intralogistics industry,” remarked Dr. Andreas Gruchow, Member of the Managing Board at Deutsche Messe.

NEWS & REPORTS Hall 27 will also house large portions of the STORE & LOAD section, which in addition will occupy the entirety of Hall 13. This technology sector puts the spotlight on rack systems, factory equipment, pallets, containers, loading and unloading equipment and complete systems. In the PICK & PACK technology section, visitors will find order-picking and packing solutions, including measuring, weighing and metering equipment. This section will be housed in Hall 12, which it shares with LOGISTICS IT. The LOGISTICS IT platform was staged this year for the first time as part of CeBIT, where manufacturers of logistics software had an opportunity to showcase their solutions at the global digital industry’s leading event. Exhibitors were highly satisfied with this debut installment and plan to exhibit their software solutions as well as their control and tracking technology and identification systems at the next CeBIT, from 5 to 9 March 2013. Then in 2014 the LOGISTICS IT sector will shift over to CeMAT. For exhibitors this future annual alternation between CeBIT and CeMAT is extremely attractive, as both events are geared to fully different target groups. Whereas CeBIT is primarily geared to IT decisionmakers at the corporate level, the main target group for CeMAT consists of logistics managers.

Time-tested exhibition layout retained, with internal restructuring of display sectors As was the case for previous events, CeMAT 2014 will occupy halls 12, 13, 25, 26 and 27 surrounding the openair site at the Hannover exhibition center, guaranteeing ideal visitor orientation. The major display categories at CeMAT will remain, but have been divided up into five new technology sectors: MOVE & LIFT, STORE & LOAD, PICK & PACK, LOGISTICS IT and MANAGE & SERVICE.

The MANAGE & SERVICE sector offers logistics consultants and logistics service providers a platform for presenting their latest ideas and concepts. This section will be staged in Hall 27 in the direct vicinity of port handling technology. Thanks to a new cooperation agreement with the Munich-based “transport logistic” show, the display segment will receive new and sustained momentum as the show’s organizers at Messe München are providing a display segment from “transport logistic” at CeMAT 2014 in Hannover.

Located in halls 25 and 26, pavilions 32 to 35 and on the open-air site, the MOVE & LIFT section will be devoted to materials handling and lifting technology, including industrial trucks, cranes and hoisting equipment, aerial work platforms, continuous handling systems and overhead conveyors. It will also include the “Platformers World” showcase, which again will occupy a central location at CeMAT on the open-air site, offering visitors a comprehensive program covering the operation and rental of mobile lifting equipment and mobile height access platforms. Occupying Hall 27, port handling systems are also a featured category within MOVE & LIFT.

New Cat® D6K2:

The Cat D6K2 Track-Type Tractor.

New Cat® D6K2 Benefits from Refinement in Blade Control, Fuel Economy, Productivity, Performance, Operator Comfort, Serviceability and Emissions Control Cat® D6K2 The new Cat® D6K2 Track-Type Tractor delivers unmatched finish grading performance and improved fuel economy. New Stable Blade Control feature utilizes technology which complements operator blade control input, making it the best finish grading tractor in the industry. Eco Modes, both forward and/or reverse, improve fuel economy up to 22% depending on the applications for lower operating costs. The new D6K2 uses the powerful Cat C6.6 ACERT™ engine that meets Stage IIIB and Tier 4 Interim emissions requirements. K2 models feature hydrostatic drive with Traction Control, which reduces track slip at maximum load. New wider blades allow more ground to be covered in one pass and provide up to 8 % productivity improvement in slot dozing applications. New manual adjustable pitch allows the operator to control blade pitch fore/aft for maximum productivity in various material conditions.

Issue 03 | 2012

The K2 models blend these new features with the basic field-proven design of their K Family predecessors, a design that includes single-lever travel/steering control, spacious operator’s station with standard air conditioning with cab-equipped, single-lever blade control, Cat Sealed-and-Lubricated Track (S&LT) or Cat SystemOne™ undercarriage for lowest undercarriage cost per hour. The D6K2 benefits from the recently introduced undercarriage improvements of the D6K. The combination of eight bottom rollers and two carrier rollers allow for a smoother ride and better finish grading capabilities at a higher speed. Net power ratings are 97 kW/130 hp at 2,200 rpm. The new C6.6 ACERT engine features Air To Air After Cooling, a new electric fuel priming pump, and a passive regeneration system for emissions reduction.


NEWS & REPORTS Operating Efficiency Stable Blade Control supplements the operator’s blade-control input, helping to reduce operator effort and fatigue, while increasing productivity in finish grading applications. The Stable Blade Control feature remains activated unless cancelled by the operator. For even more productivity, the blade pitch adjustment design has been simplified to allow the operator to adjust blade pitch, for example, selecting a more aggressive setting for hard blade loading or pitching the blade rearward for more blade carry capacity. The D6K2 offers wider VPAT blades (both standard and foldable versions), which can boost productivity as much as 8%. The new Eco Mode system for the D6K2 model can improve fuel economy by up to 22 per cent by reducing engine speed when maximum rpm is not required. Eco Mode has two settings – Forward/Reverse or Reverse Only – that are selected via the rotary throttle. Once set, Eco Mode automatically controls engine speed at optimal levels, rapidly delivering back maximum engine speed and power when required. Traction Control is an operator-activated system that reduces track slippage under heavy load by sensing and controlling track speed, resulting in fewer situations where operator must lift the blade to prevent track slip. The benefits include higher production, less undercarriage wear and reduced operator fatigue. Undercarriage configurations include XL (Extra Long) and LGP (Low Ground Pressure) versions, with an LGP version that features 760 mm (30inch) track shoes.

The cab of the Cat D6K2 Track-TypeTractor.

For the ultimate in operator comfort, an optional package provides a heated/ventilated seat. Electro-hydraulic seatmounted controls isolate the operator from vibrations and the new armrests can be easily adjusted. For increased productivity and efficient grading and contouring work, the D6K2 can be equipped with the optional Cat AccuGradeTM system for automated blade control. AccuGrade can use laser, total station or satellite positioning systems as the guidance source. AccuGrade is designed to reduce the need for surveying, to eliminate rework and to unburden the operator when doing finish grading. AccuGrade has demonstrated itself as a solution to reduce overall machine operating costs in doing more, and accurate work with less fuel burned. For more information about the K2 Family track-type tractors, customers should contact their local Cat dealer.

NEWS & REPORTS Telestack Limited

Telestack install a fully customised

system as part of Investment from London Mining Company (LMC)

Telestack has recently installed a custom design mobile truck unloading, stockpiling, reclaiming and barge loading facility in Sierra Leone. Installation commenced towards the end of 2011 and has been completely commissioned and signed over in early 2012. The turnkey solution was delivered as part of London Mining Company’s Phase 1 investment and Telestack’s Sales Engineers worked closely with LMC management and LMC consultant on the project, Ausenco, to deliver the bespoke turnkey solution. LMC choose a logistic system which sees material coming from their Outetec beneficiation plant (8000 tonne per day), being trucked 40km from the mine site in Marampa into the barge loading facility in Thofeyim on the river Loko. From this point, the material is loaded onto 8,000t barges @ 1500TPH. The barges then form part of a Transhipping process, where they are unloaded via grab cranes onto Handymax vessels ranging from 37,000 – 55,000 dwt. The project consists of various stages, which ensure maximum operational flexibility for the operator, this includes: (See Figure 1)

Truck Unloading From the beneficiation plant, truck and dog units are loaded with 2 x 40t of iron ore fines with typical FE content of 65% +. The trucks then travel to LMC‘s purpose built road to the stockpiling and barge loading site. On arrival the trucks pass over a wheel wash before driving over the Telestackgrid hopper where each trailer is unloaded. The unloading hopper has a capacity of 150t (54m3) and is fully lined with low friction liners. The trailers are bottom discharge and can unload their 80t cargo in less than 5 minutes. The unloading hopper regulates the feed at between 800 - 1000 tph from the surge by means of a robust apron belt feeder with a variable height gate outlet, all custom designed and manufactured by Telestack for this project. The heavy duty apron belt feeder module is 1200mm wide and incorporates a 800kN chain. The apron belt feeder incorporates all the

strength of a normal apron pan feeder but has much better sealing properties as it can be sealed like a traditional belt feeder, therefore optimising both spillage prevention and robust feeder characteristics all to cater for the heavy surge of iron ore at 2.8 t/m3. (See Figure 2 & 3)

Stacking System From the hopper the material is transferred onto a Telestack 20m link conveyor which weighs the material by means of a dual idler belt weigher. This is used to keep records of daily, weekly, monthly and annual capacities and to monitor stocks of iron ore in the stockpile. The 20m link conveyor discharges into the feed-boot of the Telestack 850, a mobile radial and telescopic stockpiling conveyor all in one chasis which can peak at 1000 tph and has a total length of 51.2 metres. The TS 850 has been positioned on an 8 metre high plinth which utilizes the natural topography of the site and therefore allows a total stockpile height of 25 metres to be achieved. This gives


NEWS & REPORTS Figure 2 – ‘ 3D Image of unloading hopper fed from trucks to the link conveyor’

LMC approx 350,000 tonnes of material within a 180 degree radial axis. Material is stacked at approx 8000 - 10000 tonne per day which means the stockpile has maximum between 35 - 44 days complete production without any shipments. All maintenance is carried out via access walkways and all transfer points are lined and incorporate high valley angles to minimise blockage potential especially in the rainy season. (See Figure 4 & 5) The operator cabin is located at the optimum point to allow best viewing points for truck unloading and stacking. Also, strategically placed metal halite flood lights allow for 24 hour operation.

Reclaiming System From the stockpile a WA 600 Komatsu wheel loader reclaims material from the pile and feeds a Telestack track mobile hopper feeder with an 18m3 apron belt feeder. The apron belt feeder (50 tonnes) regulates the feed of the heavy surge from the 28t dump (10m3) bucket of the WA 600. Both apron belt feeders are designed to be started under full load condition. The reclaim hopper is located in the centre line of the stockpile to minimise the load and carry distance. The single WA 600 can comfortably deliver between 1200 1500 tph. The feeder then transfers the material onto a Telestack 27.5m link conveyor which weighs the material and also takes a sample using an Certified ISO 308 standard sampling unit. The ESSA sampler is a reverse spoon type design and takes a cut from the falling stream as per iron ore best practicesampling procedure. Sampling can be done a) Manually b)Set intervals on a timing basis c) Set intervals on a tonnage basis. (See Figure 6 & 7)

Barge-loading System From the link conveyor the iron ore is transported to a Telestack TS1550, a mobile radial telescopic shiploading conveyor operating at 1500TPH. The TS 1550 has an operating cabin located at the end of the outer conveyor to ensure maximum visibility when loading of the barge. The operator trims the barge by means of the TS1550 barge loaders radial telescopic and luffing capabilities. This technology ensures they can trim the entire barge from one feed-in position to enhance production rates and limit Figure 5 – ‘TS 850 Radial Telescopic stacker stockpiling over Plinth @ 1000TPH’

NEWS & REPORTS Atlas Copco Construction Tools

A world first: Atlas Copco SB 702, the only 700 kg hydraulic breaker with a solid body

tlas Copco’s new high-performance hydraulic breaker, the SB A 702, makes light work of a wide range of gardening, landscaping, construction and demolition jobs. Intensive research, innovative product design and Atlas Copco’s know-how in the field of breaker technology, has resulted in lower fuel consumption, lower vibrations and less noise.

Unusually compact The unique aspect of the SB 702 is its solid body, a feature which no other breaker in the 700 kg class has. A one-piece housing construction makes the SB 702 unusually compact and easy to handle. The percussion mechanism and guide system are integrated into a single block of steel, eliminating the need for side bolts. The integrated, maintenance-free accumulator is easily accessible yet well-protected from bangs and knocks.

Easy to set up and service Der SB 702 toleriert eine breite Spanne von ÖldThe SB 702 works with a wide oil flow range and can therefore be installed on a broad variety of carriers. In case of hydraulic overload, the SB 702 is protected by an integrated protection valve which prevents damage to the breaker and helps avoid downtime. The SB 702 is easy to set up and always ready for action. It requires very little maintenance and when it needs attention, it’s easy to service. Double tool retainer bars minimize stress and wear on the working tools. Changing the working tools is easy thanks to the patented retainer bar lock system, and the floating lower bushing can be replaced by the operator on-site with standard hand tools.

Energy recovery boosts productivity Thanks to energy recovery, the SB 702 provides much higher percussive performance. While the impact energy remains constant, the breaker increases the blow frequency, which increases percussive performance. This, in turn, increases efficiency, and greater efficiency enables higher productivity with lower fuel consumption. Energy recovery also helps to absorb recoil, which means less wear and tear on the carrier and a higher level of comfort for the operator.

Copco is celebrating the 100th sale of its Scooptram ST7 loader, confirming the international Atlas success of this new generation LHD in terms of underground loading technology and design. Vostok – Metall TransLLP of Kazakhstan has become the company to place an order for the world’s 100th and Atlas Copco’s bestselling loader Scooptram ST7. The loader, to be delivered in July, will be used for contracting underground development work at Ridder- Sokolnyi mine which is a gold mine of Kazzinc, located in East Kazakhstan region. This milestone sale confirms the global success that this Scooptram loader has been enjoying since its launch in 2010.

introduce the Scooptram ST7 at its white marble mine in Hermsdorf near the Czech border, and now also has a second unit at work in a new fluorspar operation in the same region. Service intervals are longer than for older generation LHDs at the mine, and fewer spare parts are needed due to improved parts wear.


The vehicle features an air conditioned cab, lower noise levels, improved lighting and more efficient emergency/ alarm systems. It also has excellent traction control which is easy on the tires, meaning fewer tire changes or longer tire life.

It is a journey that began in the field test stage when Lovisa Mine of Sweden gave it top marks for productivity, serviceability and comfort, reporting dramatic improvements in loading operations as well as the operator’s underground working environment.

But perhaps the most significant advantage is fuel efficiency. The Scooptram is reported to consume just 10 liters per hour with its water-cooled Cummins QSB6,7 193 hp, EPA Tier 3/Stage III engine, which is typically half that of the mine’s older LHDs.

Comfort, safety and productivity

The on-board computer calculates the optimum power needed at any one time during operations, resulting in lower fuel consumption and lower emissions, compared with operating on full throttle for most of the time.

All of the machines can be configured for loading the material into dump trucks or depositing it as a windrow behind the machine. More than two dozen cutting roller designs are available as standard, while additional configurations are developed and built for the specific task at hand. The surface minersâ&#x20AC;&#x2122; fields of application include opencast mining and routing work on roads, railway lines and tunnels. They enable the selective extraction of valuable minerals, coal, limestone, gypsum, bauxite, phosphate and iron ore with great purity. Constant expansion of the spectrum of use means that surface miners are also used for special applications in salt mining, granite, kimberlite and oil shale.

Kleemann crushing and screening machines The Wirtgen Group also offers a wide range of jaw, impact and cone crushers and as well as screening machines for processing mineral raw materials. Kleemann has been in the business of processing natural stone for more than 150 years. Pieces of rock obtained from drilling and blasting work in quarries are processed to defined grain sizes. These classified final granulations are used as standardized additives for concrete and for asphalt base, binder and surface courses in road construction as well as civil engineering. In addition, Kleemann products are designed to handle the hardest minerals and materials in the mining industry. Kleemann provides its customers with application consulting for selecting the right machine to suit their requirements. This ensures the most cost-effective mining of the given product in the daily production required.

17. Kolloquium

Bohr- und Sprengtechnik 21. und 22. Januar 2011 in Clausthal- Zellerfeld

rs e ap p r o f l l a c Profil Die erstmaligen Sprengarbeiten im Bergbau des Oberharzes im Jahre 1632 und die schnelle Ausbreitung der neuen Gewinnungs- und Vortriebstechnik in den Bergwerken um die damals selbstständigen Städte Zellerfeld und Clausthal können als einer der epochalsten Meilensteine in der Entwicklung der Bergbautechnik angesehen werden. Die ständige Weiterentwicklung über die Einführung der brisanten Sprengstoffe im Harz sowie die Erfindung des Dynamits im Jahre 1866 bis bin zu den hochmodernen Anwendungen im über- und untertägigen Betrieb der Rohstoffgewinnung zur heutigen Zeit waren und sind ein Garant zur Leistungsfähigkeit moderner Betriebe. Dabei war auch schon in den vergangenen Jahrhunderten stets von großer Bedeutung, sich über den Stand der Technik auszutauschen, um Innovationen oder Weiterentwicklungen zu verbreiten und abermals voranzubringen. Der langen Tradition der Clausthaler Kolloquien folgend, veranstaltet das Institut für Bergbau im Januar 2013 das dann bereits 18. Bohr- und Sprengtechnische Kolloquium in der Aula der Technischen Universität Clausthal. Seit dem Jahre 1976 werden zweijährlich etwa 300 Fachbesucher aus

Issue 03 | 2012

den Bereichen der Bohr- und Sprengtechnik im Oberharz erwartet, um sich über die neuesten Entwicklungen auszutauschen, Fachgespräche in der angeschlossenen Ausstellung zu führen und den Abend gemeinsam in geselliger Runde auf dem traditionellen Bergmännischen Abend ausklingen zu lassen. Das als bewährte Diskussionsplattform geschätzte Bohr- und Sprengtechnische Kolloquium stellte dabei stets eine lehrreiche und angenehme Atmosphäre für die Teilnehmer aus den Bereichen des Berg- und Tunnelbaus, der Bohrund Sprengtechnik, den Behörden sowie den Hochschulen und deren Lehrpersonal und interessierten Studenten dar. Herzlich laden wir zu einer neuen Ausgabe im Januar 2013 in den Oberharz!
