摘　　要：本文以潞宁煤业3302工作面为工程背景,采用理论分析及数值模拟的方法,对比分析了高位埋管及地面钻孔联合抽采、高位钻孔及地面钻孔联合抽采、高位埋管及高位钻孔联合抽采等3种瓦斯抽采方式的抽采效果,确定了高位埋管及高位钻孔联合抽采为最佳方案。结果表明,在3302工作面进行现场试验,通过对工作面回采过程中上隅角瓦斯浓度进行现场监测,两个月时间内,上隅角瓦斯浓度最大仅为0.77%,高位埋管及高位钻孔联合抽采效果良好。Taking the 3302 working face of Luning Coal Industry as the engineering background,the theoretical analysis and numerical simulation methods are used to compare and analyze the extraction effects of three kinds of gas extraction methods,such as combined extraction of high-level buried pipe and ground drilling,combined extraction of high-level drilling and ground drilling,and combined extraction of high-level buried pipe and high-level drilling.The combined extraction of high-level buried pipe and high-level drilling is the best solution.The results show that the field test is carried out in 3302 working face.Through the field monitoring of the gas concentration in the upper corner during the mining process of the working face,the maximum gas concentration in the upper corner is only 0.77%in two months,and the combined extraction effect of high-level buried pipe and high-level borehole is good.
