Abstract

Environmental appraisal is an assessment of coal mining exercises which impact on human wellbeing and society. Coal possibility adds to the improvement of a nation yet coal mining devalues the earth by contaminating air, water and soil. The Proximate Analysis of coal demonstrated the properties of coal comprise moisture, ash, volatile matter  and fixed carbon and Ultimate investigation demonstrated the estimations of Sulfur, Nitrogen and Hydrogen. Water investigation recorded the estimation of Physical  and  substance  parameter  like  pH, TDS, specific conductivity, total hardness, total alkalinity and so forth. The finding of coal investigation demonstrates that Rajnagar – Ramnagar coal is under bituminous coal and it comprises great vitality esteem because of low measure of Ash (9.58%) and moisture (7.5%) substance. The pH esteem (6.3 – 7.0) of coal mine water discovered somewhat acidic and accessible hardness (80 – 880 mg/l) of water in contemplate region cross passable breaking point. TDS (180-770 mg/l) content additionally demonstrates high estimation of colloidal and broke up solids. Sulfur (0.76%) found in the agreeable fixation. Be that as it may, the investigations of coal mining estimated the effect on the ecological and social. Coal mining influences condition through land debasement, de-forestation, contamination of surface and underground water administrations,  air contamination and  its impact on  plants and  natural life.
