Abstract
Barapukuria Coal Mine situated in the district Dinajpur. Bangladesh is playing an important role in the economy of this country by the mining of top quality coal. With coal mining, mine waste is also generated called coal spoil. Coal spoil can impose environmental threat if not treated carefully. In contrast, it can also be converted to value added product. In the present work, coal spoils collected from Barapukuria coal mine drainage water were investigated to determine the quality of the samples by physico-chemical analysis (proximate and ultimate analysis) as well as by heating value determination. 50% of carbon was detected in the samples after elemental analysis, with sulfur content less than 0.4%. Calorific value around 9300 btu/lb was obtained for the coal spoil. Moreover, moisture content, ash, volatile matter content and fixed carbon also provided fruitful information regarding the quality and economic prospect of the samples in comparison to the quality of Barapukuria coal.

Coal mining waste or coal spoil is an important issue for mine environmental protection
Summary
Coal spoil (CS) is a coal mining waste generated during mining and beneficiation of coal in coal mine. It is composed of various types of minerals, rocks and carbonaceous materials depending on the quality of mine and process of mining [1]. This CS can cause serious environmental pollution. As a result mining method can be made sustainable by minimizing waste production. This can be achieved by reusing the waste in different sectors.
