摘　　要：沿沟煤矿31701工作面作为保护层开采,下保护五煤,上保护八煤,在开采初期制定切实可行的瓦斯综合治理方案,通过回风隅角封堵埋管抽采、顶板裂隙钻孔抽采、顶板抽采巷采空区抽采,有效解决工作面开采初期瓦斯超限问题,取得良好效果,确保了31701工作面正常回采。As a protective layer for mining,31701 working face of Yangou Colliery protects No.5 coal mine and No.8 coal mine.A practical gas comprehensive treatment plan are formulated in initial stage of mining,blocking buried pipe extraction in return airway corner,roof fracture drilling drainage and goaf drainage in roof effectively solves the gas overrun in the initial stage of mining face mining,which achieves good results and ensures the normal recovery of the 31701 working face.
