摘　　要：根据矸石山自然发火特征,对矸石山自燃火区进行划分,提出了针对性的治理方案,形成了系统的矸石山自燃火区治理技术。高温区域采取挖掘火源法、表面封闭压实法进行治理;高浓度低温区域采取表面封闭压实、注浆液法进行治理;内部火区采取注浆液法进行治理。治理结果表明:矸石山表面空气中CO浓度、H2S浓度分别降至24 ppm、6.6 ppm以下,矸石山表面未出现温度异常区域,矸石山内部温度最高为70℃,符合《煤矿矸石山灾害防范与治理规范》要求。According to the characteristic of the gangue hill spontaneous combustion,carries on the division to the gangue hill spontaneous combustion,puts forward the control scheme of the gangue hill spontaneous combustion control system.using governance method of mining fire source method and surface closed compaction in the high temperature region; using the method of surface closed compaction and grouting in the high concentration and low temperature region; internal fire take the grouting liquid method. The results show CO concentration of air in gangue hill surface,H2 S concentration decreased to 24 ppm,6. 6 ppm,surface does not appear abnormal temperature region,the internal temperature of gangue hill up to 70 ℃,fit with＂coal gangue hill disaster prevention and management norms＂requirements.
