摘　　要：针对急倾斜煤层群倾角大造成的瓦斯防治困难问题,基于涌山矿急倾斜煤层群保护层开采地质条件,通过实测分析下保护层开采卸压效果,提出了在工作面回风巷施工顶板钻场采用高冒孔抽放和采空区预埋管抽放相结合方式抽放采空区瓦斯。By analysis on the pressure releasing effect of mining protective coal seam, put torward the technique of goal gas extraction using the combination of extraction and goaf embedded pipe extraction in roof drill site of mine ventilated gateway basing on Yongshan geological conditions of steep mining protective coal seam. in this way, solve the problem of gas prevention caused large angle.
