煤矿在采掘与洗选过程中,煤矸石约占原煤产量的25%～30%。这些矸石被堆积在地面,形成了一座座煤矸石山。根据对大中型煤矿的不完全调查,自燃的煤矸石山约占全部矸石山的48%,个别地区占到了65%。煤矸石山已成为人所共知的公害。它不仅污染环境,而且直接造成煤矿巨大的经济损失。分析煤矸石山自燃造成的各项损失,可以从经济效益这一侧面提高我们对治理环境污染的认识,加速对煤炭共生资源的综合利用。1 煤矸石山自燃因污染环境而带来的经济损失某市大中型煤矿有8座煤矸石山,其中有4座矸石堆积总量达1300多万吨,另外4座达300～600万 t。近年来,这8座煤矸石山有6座发生了自燃,自燃总面积达10万m~2
Coal mining and washing process, coal gangue accounted for about 25% of coal production to 30%. The gangue was piled up on the ground, forming a coal gangue hill. According to the incomplete investigation of large and medium-sized coal mines, spontaneous coal gangue hill covers about 48% of the total waste rock hill and 65% in some areas. Gangue Hill has become a well-known public hazard. It not only pollutes the environment, but also directly causes the huge economic loss of coal mines. Analysis of coal gangue hill spontaneous combustion caused by the loss can be from the economic efficiency of this side to improve our understanding of the governance of environmental pollution and accelerate the comprehensive utilization of coal symbiotic resources. 1 coal gangue hill spontaneous combustion due to environmental pollution caused by the economic loss of a city of large and medium-sized coal mines have 8 coal gangue, of which 4 gangue totaled 13 million tons, the other four reached 300-6 million t. In recent years, 6 of these 8 coal gangue hills have spontaneous combustion, with a total spontaneous combustion area of 100,000 m 2
