摘要
通过采取采空区直注液氮措施,配合工作面均压通风系统,有效治理了综放工作面采空区自然发火,为工作面回采创造安全条件,确保了工作面正常推进。这一防灭火技术的成功应用,为类似的采煤工作面回采期间采空区发火治理提供了很好的借鉴,具有很高的推广价值。
By taking liquid nitrogen direct injection in goaf, with even pressure ventilation system in working face, the goal spontaneous combustion in fully mechanized top- coal caving face was effectively controlled, which created safe conditions for the coal mining, and ensure the normal advancing of working face. The successful application of this fire control technology provides references for goaf fire governance during coal mining in similar coal mining face, and has high promotion value.
