underground mines in the earth crust. Coal mining is one of the most illegal activities going on in the country. At the same time it totally neglects the role of EIA in its pre-operational, during mining and post operational plans. Here various case studies of coal mining are done and the impact of coal mining to the environment is looked into withRead More

About 50 million tonnes/year of waste rock from coal-mining is generated in the limited area of the thickly populated Upper Silesian Coal Basin (USCB) in Poland. There are 380 coal-mining waste dumps, including 76 active dump sites covering over 2,000 ha. About 15-16 million tonnes/year of waste rock is being reused for civil engineering purposes in the same area. This brings about a problem ...Read More
Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals. Most extraction and beneficiation wastes from hardrock mining (the mining of metallic ores and phosphate rock) and 20 specific mineral processing wastes (see side bar below) are categorized by EPA as special wastes and have been exempted by ...Read More
