Mining methods in India

           Energy is vital for industrial development leading to economic growth.    In India, share of Thermal Energy is 64.6 %, Hydro : 24.7 %, Nuclear : 2.9% and Renewable:7.7 %.      Overall installed power generation capacity is around 1,51,000 MW. The soaring demand for power will necessitate a doubling of the installed capacity to the tune of 3,00,000 MW in the year 2020 as per planning Commission Projection.     Considering the limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on Hydel project and geo-political perception of nuclear power, coal will be the backbone for development of power and continue to occupy centre-stage of India 's energy scenario.       As per Coal India’s estimation as of April, 2012, the coal reserves in India are 293.49 Billion Tonnes (B Te) upto a depth of 1200 m. Of these, 118 B Te (40.25%) are proven and the share of Eastern Regional States is: Jharkhand - 40.16 B Te ( 33.99%
