摘　　要：老矿井在开采过程中不断向深部沿伸,煤层的瓦斯涌出量也急剧增加,尤其是"三软"煤层的瓦斯防治难度更大。通过对刘家梁矿工作面和上隅角瓦斯的综合治理,摸索出一套适合于"三软"煤层的瓦斯防治技术,为同一个矿区内其它煤矿的瓦斯治理探索出一条新路。Old mines continue to deep in the mining process, the gas emission in coal seams also increases dramatically, especially the ＂three soft seam＂ gas prevention and control is more difficult. Through comprehensive gas management at the working face and the upper corner in Liujialiang Mine, a set of gas control technology suitable for＂ Three Soft＂ coal seam＂ was explored, A new road was explored for gas control in other mines in the same mine.
