lecture / presentation description
Coal is the most important source of energy. Coal India Limited (CIL), a public sector coal company of the Ministry of coal, has reported the highest ever production of 538.75 MT of coal during 2015-16. This performance was made possible through better planning and monitoring of mining projects, increase in productivity, and better utilization of machinery and commissioning of new projects. In near future CIL will be concentrating on underground mining. In 2013-2014, 34.357 MT of coal was produced by CIL from underground mines. Continuous miners are being used for enhancing production in Tandsi underground coal mine of Kanhan Area of Western Coalfields Limited in difficult roof condition. In this paper the layout of the mine was studied and the support system was also considered. To meet the demand from underground coal production, more mines in India should install continuous miner systems and thereby improve both production and productivity. But detailed analysis of the layout and support system should be done beforehand as this has not been as successful as expected especially in Tandsi seams. There were numerous bottlenecks in the system.
