Coal mining - Wikipedia, the free encyclopedia. The goal of coal mining is to obtain coal from the ground.Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity .
Till 1971-73 the coal mining operation remained primarily in the private sector and the production had come up to a level of nearly 72 million tonnes per year only. The entire coal industry in India was nationalised during 1972-73 and then on massive investments were made by the Government of India in this basic infrastructure sector. India now .

India has emerged as the third largest coal producer in the world after China and USA with a 9% share of the total global coal production. While the coal production from underground mining in countries like China, USA and Australia are about 95, 33 and 20% respectively, India produces only about 15% of coal from underground mines (Prasad 2009).

The machinery available with Coal India Ltd. called open-cast mining allows drilling mostly up to 300 meters below earth’s surface, but about 40% of total coal reserves are located at a deeper depth which cannot be extracted using opencast mining.
In mining, opencast technology accounts for the major portion of the world’s coal production. In India, the demand for coal for 2016-17, was estimated to be 884.87 MT, whereas the domestic availability was estimated at 724.71 MT. The gap of 160.16 MT was projected to be met through imports ( coal.nic.in/)
In order to increase productivity there is a shift towards large scale open pit mining. In 2005 around 80 per cent of coal production in India came from open-cast mining, this compares to 20 per cent in 1971. The underground production declined from 50.56 to 43.54 million tonnes during the period 2001 to 2008. The imports of coal increased .
