石炭二叠纪3~#层煤8101工作面首采面自然发火的综合治理

Permo-carboniferous 3~# Coal Layer 8101 Work Face on Comprehensive Control of Spontaneous Combustion

马脊梁矿石炭二叠纪3~#层煤8101工作面最短自然发火期为52 d,由于首采面圈出时间达1 a之久,早已超出自然发火期,自然发火势必成为制约工作面正常生产的隐患,首采面建立注氮、注浆、束管监测监控、采空区喷洒阻化剂防灭火系统,制订火灾防治措施,确保了8101工作面顺利完成开采任务。

The horse back mine permo-carboniferous 3^# coal layer 8101 face the shortest spontaneous combustion period for 52 days, due to the time of first mining face circle for a year, is already beyond the spontaneous combustion period, spontaneous combustion is bound to become the hidden trouble of the normal production of working face, the first mining face by nitrogen injection, grouting, tube monitoring, inhibitor for the mined-out area spray fire extinguishing system, formulate fire prevention measures, to ensure the smooth completion of 8101 working face in mining tasks.
