摘要
为了解决煤矿放顶煤开采采空区防灭火问题,根据采空区的氧含量摸清采空区三带的具体位置,配备采空区注氮以及喷洒阻化剂等防灭火措施,使18101工作面采空区防灭火工作取得了显著的效果。
For the fire prevention and extinguishing in the goaf during top coal mining,based on the oxygen content,we located the positions of three zones,and used nitrogen injection,spray inhibitors,and other measures to control he fire in the goaf.The results show that the fire control measures on the 18101 work face has achieved remarkable effects.
