摘　　要：根据蒲河煤矿西一3#工作面在掘进、初采、回采期间瓦斯涌出较大的情况,在工作面掘进期间、回采期间采取了多种手段综合治理瓦斯,掘进工作面预抽、综放工作面采取深埋管远距离抽高浓度瓦斯、浅埋管近距离抽低浓度瓦斯,取得了明显成效,保证了安全生产。According to the condition that the gas emission is large on during tunneling,initial mining,end mining for west 3# working face in Puhe Coal Mine,the various means of comprehensive management to control gas in the period of tunneling,end mining,the pre- pumping is applied in the tunneling working face. In the fully mechanized caving face,the high gas pumping is carried out by the means of deep buried pipe and long distance,and the low gas drainage is conducted through the method of shallow buried pipe and near distance,which achieves remarkable results and ensures safety production.
