Coal is one of the most essential resource of our country it is widely used for power generation and as a raw material in the industries. India has the fourth largest reserve of coal in the world and is the third largest coal producer in the world. However the country has to import coal from other countries to meet the demand of coal in the market. In India coal is mined by both underground and opencast method of coal mining. However the major production of coal comes from opencast mines in India the reason behind this is that around 45% of our reserve is under shallow depth of cover and because of less production cost open cast mining method is widely used. Production from underground mines in India has remained stagnant over the period of time and introduction of new art, mass production technologies is extremely limited. In India production from opencast mines is nearly 94% and that from underground mines is limited to 6%. Coal production from underground coal mines is declining and several underground mines are closed every year due to lack of introduction of mass production technologies and by conventional method of mining the cost of production of coal is high and recovery is less. As our 45% of coal reserve is under shallow depth of cover and due to increasing demand of coal and large scale mechanization ,the reserve under shallow depth of cover will be depleted in near future. Opencast method of coal mining has major environmental impacts and land acquisition possess serious challenges to operate a opencast mines, growing social awareness about environment is bridging the gap between cost of production by opencast and underground method. While by underground method of coal mining there are less environmental problems and the better quality of coal from the greater depth can be extracted by introducing mass production technologies in the underground coal mines. With this background, this paper has been prepared on the basis of data collected from reports, research papers and articles. Here we have made an attempt to understand the need to change status of underground coal mining in India
