THE IMPACT OF DISPOSAL AND TREATMENT OF COAL MINING
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.
