受天山北麓阜康矿区煤田火烧带的影响,新疆大黄山煤矿+735中大槽综放工作面回采后期,上覆岩层在大范围垮落后与已治理的煤田火区连通,造成上覆的原仓储式采空区遗煤自然发火而波及该工作面。在科学判定自燃火源位置的前提下,有序实施“打钻充填胶体、稠化泥浆隔离阻断、注氮惰化逐段锁风启封、预先阻化上覆仓储式采空区浮煤、低风量供风”等综合技术措施后,使自燃灾害得到安全有效治理,保证了该面安全回采。 Affected by the coalfield fire belt in the Fukang Mining Area north of Tianshan Mountain, the +735 medium-large caving coal face working face of Datangshan Coal Mine in Xinjiang at the later stage of post-mining, the overlying strata connected with the coal field fire area under control after a large area collapse, The original storage of coal mined area left spontaneous combustion of coal and affect the face. In the scientific determination of the location of spontaneous combustion sources, under the premise of orderly implementation of drilling colloidal filling, thickening slurry isolation block, the nitrogen injection of nitrogen by paragraph lock wind Kai, pre-resistance overlying the warehouse goaf floating coal , Low air volume for wind "and other comprehensive technical measures, the spontaneous combustion of disasters to be safe and effective governance, to ensure that the surface of safe mining.
