Abstract
Mining activity also create tremendous pressure on local flora and fauna particularly where diversion of forest land takes place for mining purposes. The effect of mining on ground water level, silting of surrounding water bodies and land are also great concern. Coal mining contributes largely towards economic development of the nation although it has a great impact upon the human health. It also has its impact on socio-cultural aspect of the workers and people residing in and around coal mining areas. Thus a holistic approach for taking up to mining activities, keeping in mind concerns for adjoining habitats and ecosystem, is the need of the hour. This requires identification of various sites where minerals exist and various factors ranging from appropriate angle of slope of overburden dumps, safe disposal drains, and safe techniques to various silt control structures etc. In India Coal companies are now working towards “clean coal” strategies, which aim to reduce environmental impacts. The reduced ash contents of the washed coal increase the thermal efficiency of combustion. Which in turn make a direct impact on reducing emission of pollutants. However the coal washing requires extra water and it can turn towards a pollution free society.

Primary data are collected from a structured interview schedule with the officers of Coal India Ltd. and secondary data are collected from CMPDI records, journals of IICM (Indian Institute of Coal Management) and books related to coal mines
The demand for electrical energy in India is growing at a rate of 9% per year which can be met by additional power generation by coal fired generators
Summary
Pollutants produced in mining to burning of coal damage the earth surface to the atmosphere, the hydraulic regime to bio-diversity and threaten the very survival of humankind by global warming. A basic approach to the clean coal initiative is to mine coal with the minimum quality dilution, to prepare coal to segregate waste rock and to stow it back below the earth crust; to transport coal with a minimum vehicular exhaust, noise and to use it for industrial purposes with high fuel efficiency, minimum generation of waste and greenhouse gases. Various technologies are undergoing development in order to improve the quality of coal during and after mining and to provide an environmentally satisfactory method of using coal as a basic fuel for power production. The field study was conducted from the Coal India Headquarters in the year of 2012
