TECHNOLOGICAL INNOVATIONS IN COAL MINING INDUSTRY

Associated with production of coal, mining industry also is a part of indirectly producing about 20 % of Coal as by-product of Thermal Power stations (about 0.67 Kg of coal for generating one unit –KWh of electric power). However, its utilization is nearly 50% of the production (2009-10), which is very less in
