从自燃火灾发生的一般规律、气体分布规律和实际存在的条件出发,深入分析了32211工作面自燃火灾的原因,并准确判断了隐蔽火源的位置。然后分阶段实施封闭火区、喷浆堵漏、打钻注胶和均压通风等综合性措施灭火,成功地扑灭一次自燃火灾。
Based on the general law of occurrence of spontaneous combustion, the law of gas distribution and the actual conditions, the cause of spontaneous combustion fire in 32211 working face is analyzed in depth and the position of concealed fire source is accurately judged. Then a phased implementation of a closed fire zone, grouting, plugging and drilling plastic injection and pressure equalization ventilation and other comprehensive measures to extinguish the fire, successfully extinguished a spontaneous combustion fire.
