摘　　要：为了解决煤炭开采过程小煤柱工作面易发生自燃的问题,对工作面防灭火系统进行设计,通过数值模拟给出了易发生自燃位置,在工作面已有防灭火系统的基础上,给出了一种基于三相泡沫、结合注浆、钻孔、注惰等综合防灭火方案,通过验证,发现经过治理采空区能够消除自燃点,为矿井安全高效开采提供一定的参考。In order to solve the problem of spontaneous combustion of small coal pillar working face in coal mining process,the location of spontaneous combustion is given by numerical simulation.Based on the existing fire prevention and extinguishing system on the working face,a three-phase foam,combined grouting and drilling is presented.Through verification,it is found that the spontaneous combustion point can be eliminated after controlling the goaf,which provides a certain reference for safe and efficient mining of the mine.
