深部矿井工作面自然发火综合防治技术

Comprehensive Prevention and Control Technology of Spontaneous Ignition in Deep Mine Working Face

针对深部矿井工作面自然发火的问题,以邢东矿1227工作面为工程背景,分析了煤层自然发火的条件,确定了生产中的重点防治区域,最终采取了科学合理的综合防治技术措施。实践表明,自然发火防治效果良好,有效地解决了1227工作面煤层自然发火问题,保障了1227工作面防火安全,实现了工作面的安全回采,为邢东矿其他工作面的安全回采提供了借鉴。

Aiming at the problem of spontaneous ignition in deep mine working face,taking 1227 working face of Xingdong Coal Mine as the engineering background,this paper analyzed the conditions of spontaneous ignition in coal seams,determined the key prevention and control areas in production,and finally took scientific and reasonable comprehensive prevention and control technical measures.The practice shows that the prevention and control effect of spontaneous ignition is good,which effectively solves the problem of spontaneous ignition of coal seams in 1227 working face,ensures the fire safety of 1227 working face,realizes the safe mining of working face,and provides a reference for the safe mining of other working faces in Xingdong Coal Mine.
