THE IMPACT OF DISPOSAL AND TREATMENT OF COAL

2007-9-5  coal mining wastes is about 15% of coal production, which varies from 10% to 30% with the change of geological and mining conditions. Therefore, it is estimated that the annual production of coal mining wastes is about 315 million tons for underground coal mining after 2005, which accounts for a quarter of total industrial solid wastes.

Management of coal combustion wastes

2019-12-11  Management of coal combustion wastes 5 Burning coal in a coal-fired power plant produces a variety of solid residues known as coal combustion products (CCPs), coal combustion residues (CCRs) or coal combustion wastes (CCWs). CCPs are now more commonly called coal combustion by-products (CCBs) because of their increasing beneficial use.
