摘　　要：以石圪台矿22^(上)104工作面为研究背景,详细介绍了针对易燃煤层的综合防灭火技术手段,主要包括束管监测、煤层注水、黄泥灌浆、井下注凝胶、喷洒阻化剂、采空区注氮以及通过封堵地表裂缝、端头封堵等减少采空区漏风量的技术手段。该综合技术手段对于易燃煤层火灾防治效果显著,104工作面回采整个阶段,未出现自燃发火征兆,实现了采空区遗煤零自燃、工作面安全回采的目标。Taking the 22 upper 104 working face of Shigetai Coal Mine as the research background,the comprehensive fire prevention and extinguishing techniques for imflammable coal seams are introduced in detail,including beam tube monitoring,coal seam water injection,slurry grouting,underground gel injection,spraying inhibitor,nitrogen injection in goaf and reducing air leakage in goaf by plugging surface cracks and end plugging.This comprehensive technical approach has a significant effect on the fire prevention and control in imflammable coal seams.During the whole stage of mining in 104 working face,there is no signs of spontaneous combustion,which achieving the goal of zero spontaneous combustion of residual coal in the goaf and safe mining of working face.
