郭家河煤矿矸石山自燃综合治理技术研究与应用

Study on comprehensive control technology and application for spontaneous combustion of gangue hill in Guojiahe Coal Mine

煤矸石自燃不仅污染环境,而且威胁附近居民安全。根据当前煤矸石自燃治理技术的发展,提出了一种煤矸石自燃新治理理念——钻孔注浆+边坡防护的综治理方案。治理方案在郭家河煤矿进行了应用,取得了良好的治理效果,为矸石山后期堆放和治理积累了经验和方法,同时对其他同类型矸石山治理具有指导意义。

coal gangue spontaneous combustion will cause serious environmental pollution and threaten the safety of nearby residents.According to the development of coal gangue spontaneous combustion control technology,a new treatment concept of coal gangue spontaneous combustion,namely drilling grouting and slope protection,was put forward.The treatment scheme has been applied in Guojiahe Coal Mine and has achieved good treatment effect.Valuable experience and methods have been accumulated for the later stacking and treatment of gangue dump.Meanwhile,it has guidingsignificance for other similar gangue dump.
