FROM THE EDITOR Miners involved in exploration know this too well: aer spending so much time, manpower, eﬀort and resources digging and looking for traces of mineral deposits, and unearthing more questions than answers, he has no choice but to continue the exploration. Welcome to another edition of Africa's favourite bi-monthly mining publication which we hope will bring more insights about the mining sector. In this issue we feature the ambitious bio-diesel projects by Konkola Copper Mines (KCM). According to the company, the project aims to cultivate elite Pongamia Pinnata trees for bio-diesel production at a mining waste site of 650 hectares of land, where 400,000 trees are to be planted at an estimated cost of US$7 million. Mine automation is increasing productivity and reducing costs at an unprecedented rate to many mining companies. We give an overview of the advantages of adopting this initiative especially in the digital age.

Alecto Minerals advances operationally at Mowana LSE-listed Capital Drilling has been awarded the contract for drill and blast and is currently mobilising its equipment to site. In the interim, using a local contractor, the rst production blast is expected by the end of this month.
e conventional crushing and screening circuit has been successfully operating for two weeks, stockpiling crushed ore. Aer initial commissioning of the process plant, test production has now commenced, producing saleable concentrate up to 28% copper which will comprise part of the rst tranche of product to be delivered to Fujax Minerals and Energy, under a ve year copper oﬀtake contract.
Giant Transport Holdings, the Alecto Minerals' mining contractor for the project has commenced operations for an initial period of six months. Vincent (Paddy) Conran has been appointed as general manager for the project with over 25 years' experience in mining and mineral processing
Alecto Minerals believes that early test production strengthens the value proposition of Mowana and, accordingly, the estimated timetable for re-admission has been pushed back, anticipated to complete by the end of May 2017, to ensure that the value of this production is accounted for and represented on re-
AIM-listed Alecto Minerals, has made signi cant operational strides at its recently acquired Mowana copper project in Botswana.
admission “We are moving at speed towards delivering continuous production and rst sales at Mowana meaning that the atmosphere on site is buoyant, particularly given that the rst blast is anticipated in just a matter of days,” says CEO of Alecto Minerals Mark Jones. “ere are still some hurdles to overcome before we can announce that we are in full scale production, but our project is being de-risked on a continuous basis, and we enjoy fantastic relationships with excellent operational partners, which have the expertise to help us deal with any challenges.”

Southern Africa records rst electricity surplus in 10 years Southern Africa is experiencing surplus electricity generation capacity for the rst time in a decade, thanks to the success of regional cooperation in energy planning during the past few years. Figures released by the Southern African Power Pool (SAPP) show that the 12member pool is sitting on surplus peak period generation capacity of 919 megawatts (MW). “e excess is much higher if we look at oﬀpeak periods,” acting SAPP Coordination Centre Manager, Alison Chikova, told the SADC Energy ematic Group (ETG) during its biannual meeting in Gaborone on Monday 27 March. Chikova said the excess was partly because of the slowdown in the South African economy but also due to the impact of a coordinated approach in implementation of the SADC energy programme. Chikova said South Africa has excess
| Mar - Apr 2017
capacity of 5,797MW, largely due to the economic slowdown and the commissioning of 2,550MW of additional generation capacity from six new projects in 2016. e six projects include the 999MW Ingula power station owned by state enterprise Eskom as well as ve others involving power generation through wind, gas and solar photovoltaic technologies that were commissioned by Independent Power Producers. Angola had largest number of projects commissioned in 2016, contributing 780MW or about one h of the 4,180MW new capacity commissioned last year. Other signi cant contributions were from Zambia and Zimbabwe where new Indepent Power Projects projects added 300MW and 200MW respectively. Chikova revealed that SAPP member countries plan to commission more than
30,000MW of new generation capacity between 2017 and 2022, about half of which would come from South Africa. However, the increased generation capacity in Angola, Malawi and Tanzania is only available domestically as the three countries are yet to be interconnected to the rest of the SAPP grid. New generation capacity installed in any of the three non-participating countries is not accessible to the nine other members of SAPP – Botswana, the Democratic Republic of Congo, Lesotho, Mozambique, Namibia, Swaziland, South Africa, Zambia and Zimbabwe. ere are plans to tap into the installed capacity of these three SAPP members through the implementation of several interconnector projects. ese include the Zambia-TanzaniaKenya interconnector project that is expected to connect the SAPP grid to the
Mining NEWS one operated by the Eastern Africa Power Pool – in addition to linking the Tanzanian power network to other SAPP member countries. e Zambia-Tanzania-Kenya interconnector is expected to be ready by the end of 2019, according to Chikova. Other interconnector projects are expected between Mozambique and Malawi as well as between Namibian and Angola. e target dates for commissioning these are in 2020. Gas is increasingly becoming a major source of electricity in the region, accounting for 995MW or almost 24% of all power generated in 2016 – from two projects in Mozambique and one each in South Africa and Tanzania. Unlike in the past where coal- red plants contributed the largest share of new generation capacity, 2016 saw only one new coal project in Zambia coming on board with a capacity of 300MW. e move towards renewable energy follows a resolution made in 2012 by southern African countries to increase the uptake of cleaner and alternative energy sources. e long-term target set by SADC is to achieve a renewable energy mix in the regional grid of at least 32% by 2020 and 35% by 2030. According to the African Development Bank, southern African alone has the potential to become a “gold mine” for renewable energy due to the abundant solar and wind resources that are now hugely sought aer by international investors in their quest for clean energy.
Investment Destination in Africa an independent research arm has named Botswana, as the most attractive destination. According to Investment Destination in Africa's latest Investment Index Botswana scores highly based on a range of factors that include improved credit rating, current account ratio, import covers and eases of doing business e research says Botswana is the most attractive economy for investments owing into the African continent. Prof Mthuli Ncube , Head of Quantum Global Research Lab commenting on the Index said despite considerable external challenges and the fall in oil prices, many of the African nations are demonstrating an increased willingness to achieve sustainable growth by diversifying their economies and introducing favourable policies to attract inward investments. “Botswana is a case in example – its strategic location, skilled workforce and a politically stable environment have attracted the attention of international investors leading to a signi cant in ux of FDI,” Prof Ncube said. According to the report, the top ve African investment
Botswama leads the pack on investment attraction destinations attracted an overall FDI of $13.6bn. Morocco was ranked second on the Index based on its increasing solid economic growth, strategic geographic positioning, increased foreign direct investment, import cover ratio, and an overall favourable business environment. Egypt was ranked third due to an increased foreign direct investment and real interest rates, and a growing urban population. e fourth country on the list, South Africa, scored well on the growth factor of GDP, ease of doing business in the country and signi cant population. Whilst Zambia was the h country on the list due to its signi cant domestic investment and access money supply. “With a population of over one billion people and rapidly growing middle class, Africa clearly oﬀers signi cant opportunities to invest in the continent's non-commodities sectors such as nancial services, construction and manufacturing amongst others,” Prof Ncube said. He said structural reforms and greater private sector involvement are crucial to unlocking Africa's true potential.

Environment & communities are top priorities - Exxaro Since its establishment during a time when BEE legislation oﬀered many opportunities until now, Exxaro has faced and overcome many challenges. But it is not only visionary leadership and courage that led the company to great heights; there were other factors at play as well. “A key aspect in achieving so much is the calibre of the people employed by the company. We have smart, hard-working people who have worked with us to get us through the diﬃcult times,” says Mzila Mthenjane, executive head: Stakeholder Aﬀairs, Exxaro. “We will be building on this people foundation by emphasising excellence in all our business activities, following the review of our business model during 2016,” adds Mxolisi Mgojo, CEO of Exxaro Mthenjane adds that the company has great resources in terms of people and coal. It has

made some good investments, and some not-so-good investments, and has applied the lessons learnt from the latter. “We are also an entity that has demonstrated that we are sensitive to the environment. We have also adhered to the transformation legislation in the Mining Charter and, in many instances, outperformed the targets,” says Mthenjane. Big challenge e ability to connect with communities is a challenge for the company. “We spend a lot of time trying to demonstrate the good that we do. We closely examine our past i nt e r a c t i ons w it h c om mu n it i e s t o determine where we might be missing the opportunity to build the kind of relationships that really provide an environment where our operations can exist in harmony with communities. “Communities can see the bene t of having
those operations in place, but I think there are much bigger problems in communities than what a single company or operation can manage in the short term. We need to be long term in our perspective and look for opportunities where we can make a sustaining and real diﬀerence,” explains Mthenjane. e company has done much for communities close to its operations; most recently, it demonstrated its eﬀorts with the community close to a new mine in Belfast, which will be directly aﬀected by its planned operations. e community will have to be relocated and the company has been going through a structured relocation and engagement programme with the community. is engagement involves determining how the community will be impacted, nding a new location, and designing appropriate
houses for those being relocated. “To ensure that the relocated households are not further inconvenienced, all the amenities they are accustomed to will be within close proximity to the new location. e new houses will be built better than the current homes, and the sustainability of the residents' livelihoods will be a priority,” says Mthenjane. He adds that the company's entire approach towards its socio-economic impact has been t o i mprov e t h e l i v e l i h o o d s of t h e community. erefore, the company takes a holistic look at the quality of life residents will experience throughout their time in the community. New mine e Belfast mine will replace coal tonnes previously produced from the Inyanda Mine that closed in 2015. e volume of the new mine will also contribute to an increase in export tonnes. e new mine will be opencast and will result in various new jobs being created. “It is a green eld project with a new mine design, a new location for a new pit, and there will be new processing facilities. All the coal produced will be destined for
export,” says Mthenjane. “We are not making the mistake of leaving the environmental considerations until the end of the mine. In our planning of this new mine we have ensure that we have the least impact on the community and the environment, both during development and operation,” says Mthenjane. He explains that, while mining, the company will minimise the impact on the environment in two ways. Firstly, the mine has been designed, from the beginning, to have a water treatment plant to ensure better water stewardship in the area, which is sensitive due to the nearby wetlands and the agricultural activities. Secondly, the mine will continuously and immediately rehabilitate the area while mining. “We will investigate the potential of using the surface of the land, which could be rehabilitated for agriculture without putting a burden on the environment or changing the biodiversity,” explains Mthenjane. Other than the Belfast mine, Exxaro will also be investing in Leeuwpan, Mpumpalanga, by developing an extension of the existing mine.
Enterprise and supply development As part of the company's enterprise and supply development plans, it is investigating the best possible ways to develop and invest in local businesses. “At Belfast, for instance, we will look at the services required and provision thereof. We also plan to invest large amounts of capital in both the Lephalale and Mpumalanga projects. We want to have a lasting impact in terms of the procurement and development of those projects. Over the next ve years, we will be spending close to R17 billion on coal projects in these two areas,” says Mthenjane. Future plans Exxaro still sees a future in coal, as it has been an important element in South Africa's energy value chain. “We have also invested in wind farms, as we are very interested in the energy space, not just in energy generation, but energy services as well. “With coal being the biggest part of our business today and looking at the potential challenges going for ward, we are investigating other opportunities as well, such as commodities that are essential to the sustainability of human life,” concludes Mthenjane.

Copper producer plants bio-diesel trees on tailings dumpsite Konkola Copper Mines (KCM) has launched an ambitious bio diesel project in the Copperbelt at one of the company's disused dump site. According to the company, the project aims to cultivate elite Pongamia Pinnata trees for biodiesel production at a mining waste site of 650 hectares of land, where 400,000 trees are to be planted at an estimated cost of US$7 million. In addition, create 500 jobs in agro-forestry, farming, bio-energy processing and energy service delivery. Matthew Nkhuwa, Minister of Works and Supply said the project has potential to signi cantly reduce the country's energy expenditure. “Government is spending huge amounts of money to import fuel into the country every month. With projects such as this, the burden on the government will be lighter and resources may be channeled to other areas for holistic development,” Nkhuwa said.
| Mar - Apr 2017
Steven Din, KCM Chief Executive Oﬃcer said the project attested to his company's commitment to invest in clean energy and best-in-breed environmental practices, as p ar t of KC M v i s i on for s u s t ai n abl e development. “e trees we have planted here will revegetate a disused dump site, suck-up impurities and x back nitrogen to the soil, improving its fertility.
Pongamia is an ideal plant for recovering a variety of waste burdens such as saline soil reclamation. Pongamia brings soils back to life as the nitrogen and carbon feed rich soil microbial communities enabling other plants to grow on previously dead soil. Also virtually every part of the Pongamia tree can be used for productive ends – biodiesel for energy, while the seedcake can be used to make briquettes for cooking and cattle feed (aer removing toxins), while the slurry can be used as a fertilizer; and because the tree is naturally repulsive to animals, bio-pesticides can be made from it.
In addition to all this, employment will be created for the local people,'' Din said. KCM is working in partnership with Better World Energy to deliver the project, which is designed to fertilise the bare land which KCM currently cannot use for agriculture purposes. In addition, the project will provide a cheap and environmental-friendly source of energy through Pongamia trees for KCM.
KCM is the country's largest integrated copper producer with mining operations in Chingola, Chililabombwe, Kitwe and Nampundwe. KCM is a subsidiary of Vedanta Resources plc a London-listed diversi ed global natural resources company and the state-owned ZCCM-IH alsoholds a signi¬ cant shareholding (20.6%) in KCM.

Kibali mine on track to increase production, but DRC policies a concern e underground operation at Randgold Resources' Kibali gold mine is on track for commissioning to start in the third quarter of this year, which will signi cantly increase production. e Democratic Republic of Congo- (DRC-) based mine is forecast to deliver around 610 000 oz of gold this year, up from 585 000 oz in 2016, with production scheduled to rise to around 750 000 oz/y from 2018, when the underground operation is fully operational. CEO Mark Bristow noted that Kibali ended 2016 with a creditable performance aer having to contend with a range of operational challenges, as well as the constraints imposed by limited open pit mining exibility. In addition to dealing with these issues, the Kibali team succeeded in keeping the underground development on track, successfully constructing and commissioning four ultra ne grind mills in the metallurgy circuit, as well as progressing work on the mine's second new hydropower station, which was commissioned in February. e third and last of the new
hydropower stations is currently being built by an all-Congolese contracting group. “Kibali has stayed on course to become one of the world's great gold mines despite the challenges of last year and the volatile political climate in the DRC at present. “Randgold remains committed to the DRC and is con dent that its government, politicians and civil society have the will, as well as the capacity to work together to secure the country's future. “We, therefore, continue to invest in exploration here and to lead the way in developing the north-eastern DRC as a major new gold mining region. Our engagement with the country and its people is also evident in our substantial investment in local economic development and community upliment programmes. ese include macro and micro agribusinesses designed not only to provide regional food security but to generate surplus produce for export,” said Bristow. It was a source of concern, however, that the DRC government had once again signalled
its intention of reviewing the country's 2002 mining code with the clear intention of increasing State revenue, Bristow said. is could have a negative impact not only on the mining industry, but also on the economy. “Now more than ever, the DRC should be focused on retaining its existing investors and attracting new ones. It's certainly not the time to harvest more from less for short-term gain. It's my sincere hope that this time round, the government will engage the mining sector fully in the proposed review to achieve an outcome that will be in the best interests of the Congolese economy, as well as the country's mining sector,” he said. “e existing code is in fact a good one but it is not always being applied eﬀectively and there are still many mining operations that do not operate under the code. ere are also issues and challenges which mining companies are having to face which make operating in the DRC more challenging. In Kibali's case, these issues include more than $200-million in unpaid [tax] refunds.

DRC Mining Week expands to connected sectors THE award-winning Democratic Republic of Congo (DRC) Mining Week returns to Lubumbashi in June with a broadened focus to include the agriculture, energy and construction. Again, thousands will gather for practical annual mining and industrial expo.Event Director, Elodie Delagneau, says DRC Mining Week is well established as the leading mining expo in the region and has been around for a long time because of close collaborations with stakeholders, including industry to government. “e event will always support the mining sector with the latest technology and services displays, free training workshops and high-level strategic conference” says Delagneau. Agriculture, energy and construction are related and complementary sectors to mining. Delagneau points out DRC is not the only

country looking to diversify in anticipation of the end to the commodity super-cycle and slowdown in global growth. “e national and provincial governments are therefore looking to increase their eﬀorts to bring suppliers and investors' attention to the potential of local agricultural production – a strategy that proved eﬀective in the past with mining.” As is becoming norm, DRC Mining Week has already secured the early and impressive support of the industry through the diamond sponsorship of Engen and the platinum sponsorships of Sodexo, Standard Bank and Tenke Fungurume Mining. Atlas Copco, Copperbelt Energy and Xingye are con rmed as gold sponsors.' Earlier this year, DRC Mining Week was

Randgold’s Kibali mine heads for full production e Kibali gold mine's underground operation, which will signi cantly increase production, is on track to start commissioning in the third quarter of this year, Randgold Resources chief executive Mark Bristow said at a media brie ng here today.

e mine is forecast to deliver approximately 610 000 ounces of gold this year, up from 585 000 ounces in 2016, but annual production is scheduled to rise to around 750 000 ounces from 2018, when the underground operation will make it fully functional. Bristow noted that Kibali ended 2016 with a creditable performance aer having to contend with a range of operational challenges as well as the constraints imposed by limited open pit mining exibility. In addition to dealing with

Congolese contracting group. “Kibali has stayed on course to become one of the world's great gold mines despite the challenges of last year and the volatile political climate in the DRC at present,” he said. “Randgold remains committed to the DRC and is con dent that its government, politicians and civil society have the will as well as the capacity to work together to secure the country's future. We therefore continue to invest in exploration here and to lead the way in developing the north eastern DRC as a major new gold mining region. Our engagement with the country and its people is also evident in our substantial investment in local economic

It's certainly not the time to harvest more from less for short
term gain. It's my sincere hope that this time round the government will engage the mining sector fully in the proposed review to achieve an outcome that will be in the best interests of the Congolese economy as well as the country's mining sector,” he said. “e existing code is in fact a good one but it is not always being applied eﬀectively and there are still many mining operations that do not operate under the code. ere are also a number of issues and challenges which mining companies are having to face which make operating in the DRC more challenging. In Kibali's case, these issues include more than $200 million in unpaid TVA and duty refunds.”

Meticulous planning, tailor-made solutions, attention to detail, delivering on time and within budget and keeping clients happy – that, in a nutshell, is Cape Town-based Concargo (Pty) Ltd's secret to beating the competition in the fast-paced, highly-competitive freight forwarding and logistics industry. is success story began back in January 1987 when Concargo was founded, in Cape Town, by David and Beverley Kruyer.

I can only attribute our success and longevity in the industr y to solid partnerships with clients and service providers who have loyally stood alongside us as we've grown.' It takes teamwork Being successful in the freight forwarding industry requires teamwork and synergy of planning to ensure the smooth passage of cargo. Concargo boasts a dedicated and skilled team, as well as strategic business partners, working together to ensure a seamless and co-ordinated solution - whether transporting within South Africa or across borders into Africa. e highly experienced team has decades of experience: Greg Tighe, Projects Director has

‘Our management team is solid and has the experience to adapt to the new challenges presented by this ever-changing industry,' says Kruyer. 'Transport logistics in Africa is a vibrant and exciting industry to be part of. Our desire is to mentor a future generation by showcasing transport logistics as a career and are excited to have four logistics graduates join us as interns this coming year.'
Solutions driven Successful delivery of cargo, no matter what the load, requires skilled staﬀ to manage the oen complicated logistics. Over the years Concargo has been presented with some notable and rather unusual projects which have required intricate pre-planning and creative thinking to meet the brief, especially within tight time constraints. ese include: · Managing the transport and logistics for big budget movies such as Racing Stripes, Home Alone, Lord of War, Blood Diamonds and more · Co-ordinating and managing the transport and logistics for BMW's international media launch of its 650 cabriolet series in Cape Town · High security transportation and escorting of Grade 12 examination papers from SA printers

to the education ministries in various Southern African countries · Transportation of abnormal loads such as wind tower tubes, mining bucket wheel reclaimers, combine harvesters, 100 ton LP heaters for Medupi. One of the most challenging projects took a total of three months to complete, a month of planning and two months of transportation. It involved relocating 45 loads of bucket wheel reclaimers from Saldahna to Sishen S o u t h m i n e . Considered abnormal out-of-gauge haulage
and at 9m wide, the transportation required special permission and escorts as it snaked its way up and over the steep Piekeniersberg Pass, in four hour intervals (to allow for other traﬃc to pass) as part of the route.

According to Kruyer, service management within the framework of distribution and logistics - is the name of the game in providing reliable supply chain services from start to nish. 'Our expedited trucking provides a daily door-to-door road haulage service throughout South Africa, hauling general dry cargo from one tonne up to thirty-six tonne loads to and from all destinations as into all SADC, neighbouring and remote countries in SubSaharan Africa.

Metso Introduces A New Housing Design For LindemannTM Shredders To Expedite Maintenance Metso has developed a new housing design that cuts service downtime, facilitates the maintenance of recycling equipment and makes it easier to keep the machinery in top shape. Available for almost every Metso LindemannTM shredder model, the new solution enables multiple maintenance operations to be performed conveniently, swily and at one time. e most signi cant improvement in Metso's new housing model is the detachable front wall. e removable unit provides easier access to wear parts and speeds up the replacement of worn components. e new housing design also enables several maintenance tasks to be carried out at the same time. With the detachable front wall lied out of position with a crane, the rotor adjustment and the replacement of wear plates, for instance,
can be conveniently handled simultaneously. Minimizing maintenance downtime in production is achievable by acquiring a second Metso front wall set on stock. is makes it possible to replace the whole front wall and its worn parts immediately, and production is restarted with dispatch. All the required maintenance for the dismantled set then can be done in detail while production is up and running. During the next service break, the maintained set is put back in action. Metso's new time-saving housing design is suitable for almost all Metso Lindemann shredders. e solution is available as a retro t for existing middle housing, as part of a complete new middle housing, and as standard for all new Metso Lindemann machines. Metso is a world leading industrial company serving the mining, aggregates,
recycling, oil, gas, pulp, paper and process industries. We help our customers improve their operational eﬃciency, reduce risks and increase pro tability by using our unique knowledge, experienced people and innovative solutions to build new, sustainable ways of growing together. Our products range from mining and aggregates processing equipment and systems to industrial valves and controls. Our customers are supported by a broad scope of services and a global network of over 80 service centers and about 6,400 services professionals. Metso has an uncompromising attitude towards safety. Metso is listed on the NASDAQ OMX Helsinki, Finland, and had net sales of about EUR 2.9 billion in 2015. Metso employs over 12,000 persons in more than 50 countries.

We are actively working to develop the downstream production of copper items particularly in the Healthcare sector by highlighting the dangers of HAI`s (Hospital Acquired Infections) in hospitals and clinics. ousands of patients die in hospitals every year as a result of infections contracted in healthcare facilities. ese deaths can be avoided by installing antimicrobial copper touch surfaces in hospital wards and ICU`s. We are keen to expand the use of copper into Africa, Zambia speci cally. e CDAA would like to partner with government and the Zambian mines to pursue the downstream bene ciation of copper and produce copper products in each region with locally produced copper. e production of copper tops to bedside, overbed tables, door handles, push plates and IV stands will also create job opportunities and reduce unemployment. e introduction of copper sh cages has tremendous advantages for sh farming (Aquaculture) as copper nets are anti-biofouling which results in healthier and larger sh. e nets are also predator proof. ere are many bene ts for companies to become members of CDAA, please contact the CDAA Centre Director for further information. www.axis.com/critical_infrastructure

“Workers become fatigued when exposed to harsh environments, long working hours and unforgiving deadlines,” the whitepaper says. “In the last few years Australia has seen some of its highest temperatures on record. If le unchecked, working in hot and humid conditions can be hazardous and potentially fatal.” Providing workers with the right protection from fatigue and heat can make a signi cant diﬀerence to performance and eﬃciency, according to Kimberly Clark.
“In order for employers to eﬀectively protect t h e i r e mp l oy e e s f ro m h e at s t re s s , investments are increasingly being made into creating light and easy-to-wear coveralls.” Kimberly Clark says coveralls are not a “style statement” but are a vital piece of protective gear. “e type of clothing worn is an important factor in controlling he at

companies, and wider social take-up is booming. Prefabricated construction is the practice of assembling a variety of components of a structure at a manufacturing site and transporting those sub-assemblies to the location of the construction jobsite. Prefabricated construction is sometimes thought of as a low-end and mass produced mode of construction. In reality howe ver, it is quite t he opp osite. Prefabricated construction is becoming more common, improving in quality and has become available in a variety of budgets. Despite the perception of prefabrication, there are numerous bene ts to this type of construction. is article assesses the advantages that prefabricated construction presents for both businesses and customers. Eco-Friendly Modular construction is oen commended for energy eﬃciency and sustainable construction. Traditional
construction methods require extra materials that lead to increased waste. However, since prefabricated subassemblies are constructed in a factory, extra materials can be recycled in-house. is is a considerable improvement over sending waste directly to a land ll from a traditional construction site. Also, the controlled environment of a factory allows for more accurate construction, tighter joints and better air ltration, which in turn allows for better wall insulation and an increase in energy eﬃciency. Financial Savings One of the greatest advantages of prefabricated construction would be nancial savings. Although the perception of c ustom-made pieces may s eem expensive, with prefabricated or modular construction, this is not the case. Modular construction targets all budgets and price points, creating an aﬀordable option. Prefabrication manufacturers oen receive bulk discounts from material suppliers
which then trickles down to the cost of a construction project. Modular construction also sidesteps the possibility of unreliable contractors and unproductive staﬀ. Additionally, the reduction in construction time can signi cantly save on construction nancing costs. Flexibility Modular construction can be easily be disassembled and relocated to diﬀerent sites. is signi cantly reduces the demand for raw materials, minimizes expended energy and decreases time overall. Also, modular construction allows for exibility in the design of the structure allowing for a limitless number of opportunities. Since prefabricated construction units can be used in diﬀerent spaces, its neutral aesthetics is able to blend in with almost any building type. Consistent Quality Since prefabricated construction occurs in a controlled manufacturing environment and follows speci ed standards, the subassemblies of the structure will be built to a uniform quality. Construction site-built structures are dependent upon varying skill levels and the schedules of independent contractors. ese all contribute to the crasmanship and overall
q u a l i t y o f g i v e n s t r u c t u r e . Wi t h prefabrication, each sub-assembly is built by an experienced crew in a weatherresistant factory, with multiple quality checks throughout the entire process. Some components of the building are constructed using precise machine equipment to ensure conformity to building code. Reduced Site Disruption Since many components of a building are completed in the factor y, there is signi cantly less truck traﬃc, equipment and material suppliers around the nal c onst r u c t i on s ite. is l i m it s t he disruption of traditional jobsites that suﬀer from noise, pollution, waste and other common irritants. is streamlined approach to construction provides a far more eﬃcient atmosphere for productivity, and eliminates unnecessary distractions and interference that are typical of construction sites. Shorter Construction Time Portable construction takes signi cantly less time to build than on-site c onst r u c t i on . In m any i nst an c e s , prefabrication takes less than half the time when compared to traditional
construction. is is due to better upfront planning, elimination of on-site weather factors, subcontractor scheduling delays and quicker fabrication as multiple pieces can be constructed simultaneously. Shorter construction times allows construction companies to take on multiple projects at once, allowing businesses to grow rather than putting all their focus and resources on one or a few projects at a time. Safety Since sub-assemblies are created in a factory-controlled environment utilizing dry materials, there is less risk for problems associated with moisture, environmental hazards and dirt. is ensures that those on the construction site, as well as a project's eventual tenants are less likely to be exposed to weather-related health risks. Also, an indoor construction environment presents considerably fewer risks for accidents and other liabilities. ere are strict factory processes and procedures that protect the worker from on-the-job injury. At a construction site, although safety is of utmost importance, workers are subjected to weather-related conditions, changing ground conditions, wind and other crew members who are at the site.

Mine automation clears giant hurdle In the coming years, automation will change underground mining beyond all recognition e days of pit ponies and caged canaries the stock in trade images of the mining industry until well into the twentieth century - are long gone. Since then, new technologies began and are continuing to transform the industry. From today's 'digital mine' that's rede ning approaches to analytics and dynamic scheduling to integrated automation and cloud-enabled mobility, mining companies are increasing productivity and reducing costs at an unprecedented rate. But one area that has eluded automation for years is the loading process of the underground LHD vehicles themselves. e challenge has always been how to create an automated system with the ability to eﬀectively gauge the diﬀerence in size and con guration of rock piles as the loads are continually dispersed. Progress is also being stalled by underground conditions, which typically render camera technology ineﬀective by preventing the system from

being able to 'see' the rock piles. Mining companies, however, continue to face some major challenges for sustainable growth. A rise in demand, from the developing world in particular, has made performance improvement and cost savings key challenges within the industry. It is apparent from several case studies that operations at all levels of the industry are exploring opportunities to increase eﬃcienc y and improve s afet y and production via automation. Due to advances in automated tracking systems, control equipment, telemetry and robotics, improvement is expected in the precision and safety of mine machinery. Automation is a discipline involving many variables and equipment that includes instrumentation, sensors, nal-control-elements, control systems, networking, and communication. Bene ts of automation Decreased Process Variability One of the main ways to ensure a consistently good product is to rst ensure
that you have a consistently good process in place for producing that product. Statistical process control, in idea developed in the 1920s and honed throughout the last century, holds that in a tightly controlled process with a set norm, it is easier to see variation from that norm and nd its attributable causes. Automation helps adhere operations to much stricter protocol. Higher Quality Product When you have a well-controlled method of manufacture, you have much more control over the outcome, and can therefore work steadily toward a higher product. It stands to reason that automated processes are far less likely to fall outside of acceptable norms than those controlled by people. Lower Operating Costs One of the bigger costs in the mining and geology industry is labor. is is both because it costs money to pay workers, and because money is lost to human
ineﬃciency. Accenture explains that “if manual operator eﬀectiveness is between 50 and 70 percent, the use of autonomous equipment could potentially raise that to the 90 percent range. is could result in equipment productivity increases of 20 to 40 percent.” ey further estimate that autonomy could reduce the number of op erators by 75 p ercent, and save companies an overall 80 percent in total labor-associated costs. Better Monitoring Automated technology, such as mine planning soware, can help companies accurately model a mine environment, including ventilation and water simulations, thereby predicting and monitoring dangerous situations to help avoid loss of life. Less Machinery Wear Automated machines and operation reduce the chances that machines will be used incorrectly, potentially prolonging the life span of machines and parts signi cantly. Furthermore, automated processes don't depend on human attention to detail or knowledge of operations in order to use machinery eﬀectively and eﬃciently, nor do automated processes need to be “having a good day” in order to correctly follow
mine protocol, notice equipment failure, deal with malfunctions and otherwise protect machines. Increased Deposit Yield Deposit yield is a huge issue for mining companies, as it is their raison d'etre. Automated systems can assist by locating mine sites with small amounts of minerals, and they can dramatically increase the number of sites available to mining companies. Coal mining, for instance, is generally restricted to seams that are at least 1.3 meters across; any smaller and the challenges inherent in mining the seam outweigh the potential bene ts. Automated technologies, however, wouldn't have as much trouble with such small areas, potentially opening them up. Higher Environmental Responsibility Mine planning soware and automated processes in general can also help bolster environmental sustainability through modeling of the best ways to manage and reduce environmental impacts. By nding the best processes through simulation, organizations can then implement them without trial and error in the eld. Increased Safety Underground mining can be risky
business, with noxious vapors, ammable gases, unstable materials, possible oods, res and collapses all threatening human lives. Automated technology helps through penetration of possible mine sites or dangerous areas by sending drones or robots to map passages and collect samples so that people don't have to. Robots can also help in emergencies, carrying food and supplies to trapped workers and even hauling them to safety. Overall Process Streamlining e mining process consists of many parts and numerous operators. Automation can help organize the big picture, integrate op erat ions, pre vent waste, re duce unnecessary expenditures, model the best outcomes before attempting them, reduce variables and generally enable streamlined mining processes. At this point, automation is here to stay. e question is not whether it will last, but what forms it will take and how it will impact the mining industry overall. What seems certain is that organizations that hurry to make use of automated technologies will increase their bottom line, nesse their overall process and gain an advantage over those who wait.
