摘　　要：本文提出了俯采综采工作面邻近层瓦斯的抽放方法,以及用一条边界专用瓦斯巷道集中抽放钻孔一侧多区段无煤柱综采工作面邻近层瓦斯的方法。该方法在城子河煤矿的应用取得了较好的效果。This paper puts forward a methane drainage method for the adjacent coal seam methane of under-dip compre- hensively Mechanized coal faces,in which a boundary and special-purpose methane roadway has been used for drawing the ad- jacent coal seam methane of the borehole- side,multi-section and pillarless compre- hensively mechanized coal face.Good results have been achieved in application of this method to the Chengzihe Coal Mine

关 键 词：综采工作面 邻近层 瓦斯抽放 抽出率 矿井瓦斯
