摘要:The India ranks third in world coal production mainly due to 89% contribution from opencast mining or surface mining. Coal India (a major coal producing organization in India) produced 359.78 million tons of coal in the year 2008-09 from opencast mining or surface mining technology. It is pertinent here to mention that to mine out 359.78 million tons of coal from opencast mining, 645 million cubic meter of waste rock and soil was excavated in the year 2008-09. But a major hindrance in sustaining this level of coal production from open cast mining is area of land involved. This socio-environmental predicament requires a solution and the only possible way to reduce the area of land affected is to increase the slope angle of the waste dump embankments. However, this solution creates another problem in itself i.e. the stability of the waste rock dump. It is considered as one of the major issues faced in the open cast coal mining operation due to slope failures resulting in fatal accidents in some of the large opencast mines of India.
