In India coal is the major source of power generation. The coal obtained in India is very high in ash content and has low calorific value. Out of two methods of coal mining techniques opencast coal mining contributes to 81% of total coal generated in our country. Opencast mines having capacity of 10 million tons per annum are being in operation in India. This opencast mining activity in huge forest areas are responsible for loss of biodiversity and loss of nutrient quality of soil. Therefore, huge amount of waste is generated on the surface of the Earth while these mines are in operation phase. Generation of coal is higher that’s why there is generation of more amount of fly ash. It means that India consumes more amount of coal to generate same amount of power than other countries. Therefore, one of the major issues related to coal based thermal power plants is disposal of fly ash. In earlier times it was considered as total waste and due to its environmental hazard its use nationwide was limited to some extent. The unscientific disposal of this fly ash into rivers, open dumps the fine particles of this fly ash disperse in air and causes air pollution, degrades land and pollutes groundwater table as well. In this study, the site selected for overburden dump is W.C.L. Umred (Western Coalfields Limited, Umred) and overburden samples are collected for physico-chemical chemical analysis of samples along with the testing on fly ash to check whether cultivation on this soil can be done or not. Physico-chemical properties such as bulk density, pH, grain size distribution, electrical conductivity, available nitrogen (N), phosphorus (P), and potassium (K) and organic matter is tested. The positive results are generated so far.
