Cuprins RM11/2010. SUMMARY Ilie ROTUNJANU, Daniel ANTONIE, Viorel VOIN Consideraţii asupra caracteristicilor geotehnice ale rocilor din coperta carierelor din Oltenia în funcţie de adâncimea acestora şi influenţa lor asupra elementelor geometrice ale taluzurilor Considerations on The Geotechnical Characteristics of The Overlying Rocks in The Quarries of Oltenia According to Their Depth and Their Influence on The Geometrical Elements of Slopes The dependence of slopes geometry of in open - cast mining on the physical and mechanical characteristics of the overlying rocks in quarries calls for the careful study of the latter and the assessment of their variations. The aim of this paper is to analyze the influence of geological formations depth on the rocks strength and to establish the geometrical elements of slopes according to the geomechanical characteristics of the main rock types for the quarries in Oltenia.
Dumitru FODOR Reamenajarea zonelor afectate de exploatarea balastierelor şi carierelor Re-arrangement of The Zones Impacted by The Quarry and Gravel Pit Exploitation The paper deals with the negative impacts of the gravel pit and useful rock quarry exploitation on the environment and the most suitable methods for the re-arrangement and reuse of the waste dumps and residues deposits resulted at the exploitation and of quarry remaining voids.
Adrian Nicolae DINOIU, Emil POP, Ioana Camelia BARBU Sistem de monitorizare a sistemelor de energie regererabilă Monitoring System for Renewable Energy System One aspect not for ignoring in renewable energy is the monitoring of renewable energy systems. We need this measurement to know their characteristics, and their evolution over time. We need to know when they are working properly and when they can produce energy. Thus, in this paper is developed a monitoring system for the renewable energy systems.
Ion GHERGHE, Constantin LUPU, Doru CIOCLEA, Cornel BOANTĂ, Marius MORAR, Emeric CHIUZAN Verificarea in situ a parametrilor R0 şi K0 care caracterizează instalaţia de aeraj parţial din cadrul aducţiunii secundare Bistra - Poiana Mărului In Situ Measurements of R0 and K0 Parameters That Define The Partial Ventilation System of Bistra-Poiana Marului Secondary Water Feed System Similar to the general ventilation mode whit the help of mine ventilation installation, auxiliary ventilation is widely used in all mines, irrespective of the useful mineral substance, and is intended to provide safe and sound working conditions underground. It is a difficult job to design an efficient suction system because several parameters should be known. Each suction hole shale be designed so that it doesn’t allow a recycling of toxic and/or explosive gases, but nit catches coarse particles that night clag up even ventilation pipes.
Adrian FLOREA Posibilităţi de creştere a capacităţii haldei Uricani Possibilities for Increasing Capacity of Waste Dump Uricani Uricani is one of the few active remaining collieries from Jiu Valley, in the Meridional Carpathian Mountains. The paper deals with the stages involved in the process of computerized design in order to evaluate the remaining discharge capacity and solution for increasing the capacity of waste dump and the various over passed
obstacles in order to gain all the necessary information available from different sources. The solutions of the problem conclude the paper.
Diana MARCHIŞ, Doru EPURE, Adrian CORUI, Romulus SÂRBU Coagularea în câmp electric a apelor reziduale încărcate cu suspensii minerale The Coagulation in Electric Field of Wastewaters Charged With Mineral Suspensions The water resulted from mining industry and coal processing is characterized by a high concentration in argillaceous colloidal suspensions, which do not precipitate free not even in weeks. Waste water from U.P.Coroesti washing technological process has a lot of argillaceous colloidal substances and is recalcitrant in cleaning. There by, in order to increase the sedimentation speed there are used certain clearing reactive. The purpose of this study is to replace Zetag reactive - with coagulation role, used in present time at Coroesti processing plant, with electro coagulation in continuous electric field with consumable anode.
Grigore Iustin POPESCU, Vasile NANU, Florin Marian MIHAI Analiza cu element finit al principalelor părţi componente ale transportoarelor cu bandă din carierele de lignit din Oltenia The Analysis With Finite Element of The Main Component’s parts of Belt Conveyors from Oltenia’s Lignite Quarries Taking into account the fact that in acknowledge countries for the success on technological plan, like West Europe and U.S.A, the using of finite elements’ method, in general and integrated systems in special, it is not a method, it is a necessity, and we can say that it is necessary to align our selves at such standards. Using the analysis with finite elements, we can find constructive solutions for the increasing technical performances of belt conveyors from lignite quarries.
