冲击地压条件下高冒区自燃火灾综合防治技术

Comprehensive prevention technology of spontaneous combustion fire in high caving area of rock burst mine

胡家河煤矿因煤层较厚,且煤层自然发火与冲击地压灾害交织,在压力富集区域出现的高冒点较多且伴随着裂隙发育,该区域煤层容易自然发火,高冒区的防灭火技术非常关键。通过介绍401106回风巷高冒区发火情况,分析了导致高冒区发火的原因,提出了有效的治理方案,对治理效果进行了评价。

In Hujiahe Coal Mine,Because the coal seam is thicker and the coal seam spontaneous combustion and rock burst hazard coexist,the high caving point in the pressure enrichment area is more and accompanied by the fracture development.The coal seam in the area is prone to spontaneous combustion,and the fire prevention and extinguishing technology in the high caving area is very critical.Through the introduction of the spontaneous combustion situation in the high caving area of 401106 return air roadway,the reasons leading to the spontaneous combustion in the high caving area are analyzed,and the effective control scheme is put forward,and the control effect is assessed.
