The present study was conducted to determine the microbial diversity of soil in some coal mine generated wasteland of Raniganj Coalfield area. Seven different soil samples were collected from seven different sites namely Nagrakunda, Topsi colliery, Sidhuli, Sankerpur kenda, Bankola, Parascul, Sonepur Bazari of Raniganj Coalfield. Topography, vegetation, mining type, mining area, status of mining operation, biological reclamation activity was considered as basis of the sample selection. Soil physicochemical characteristics were also analyzed. For microbiological study, soil samples were processed according to standard microbiological techniques. The results of the present study enlighted that in our study area heterotrophic, gram negative, phosphate solubilizing bacterial population was quite high in Sankerpur kenda area whereas gram positive bacterial population was low in this area. Nagrakunda showed much higher gram negative bacterial population whereas Bankola showed lower gram negative, nitrate reducing and phosphate solubilizing bacterial population with low organic carbon, potassium content. Gram positive bacterial population was high in Topsi colliery and Sidhuli showed high nitrate reducing bacterial population. Overall, different area of Raniganj coalfield showed different picture of bacterial population with low nitrogen (except Bankola), potassium (except Nagrakunda), organic carbon (except Sonepur Bazari) and medium phosphorus content (except Sidhuli).
