摘　　要：鹤煤集团九矿3102掘进工作面瓦斯涌出量为20.6m3/t,采用交叉钻孔、双耳巷钻场和后路浅孔抽采技术,同时加强局部通风和监控系统管理,使回风流瓦斯体积分数下降到0.6%,瓦斯抽采量达569万m3,取得了良好的社会和经济效益。At 3102 working face of No.9 Mine of Hebi Coal Mining Group, the gas emission is 20.6m3/t. By applying cross hole drilling and extracing in a same coal seam, double-side drilling yard extracting and backward shallow borehole extracting as well as strengthening local ventilation control and monitoring system management, the gas concentration in return air is reduced to 0.6%, total volume of 5.69 million m3 gases extracted. This brings big social and economic benefits.
