摘　　要：为了有效控制易自燃煤层放顶煤工作面自然发火,通过对煤自然发火机理的研究,以某矿8826放顶煤综采工作面为例,分析了低位放顶煤工作面采有三种防灭火技术进行防灭火的具体方案,优化出高效率、低投入、可操作性强的三相泡沫防灭火技术措施,以更好地防止煤层自燃,值得推广使用。To effectively control the spontaneous combustion of top coal caving mining faces with spontaneous combustion coal seam,based on the research of the mechanism of coal spontaneous combustion,the coal spontaneous combustion is analyzed by taking 8826 fully mechanized top coal caving face of a coal mine as the example.The ad-vantages and disadvantages are discussed in implementation process of various fire-fighting technology of low caving working face,three-phase foam fire-fighting technical measures of high efficiency,low cost and strong operability are optimized,in order to better prevent the spontaneous combustion of coal seam.
