摘　　要：为降低赤峪煤矿2#煤层瓦斯危害,有效排放局部地点的瓦斯,采用钻孔瓦斯流量法对2#煤层超前钻孔有效影响半径进行测定,并同时采用突出指标法对测定结果进行最终确定。结果表明,综合采用钻孔瓦斯流量法和突出指标法测定煤层超前钻孔有效影响半径更具有设计针对性和施工可操作性,对赤峪煤矿2#煤层瓦斯治理工作提供实用性指导。To reduce the gas harmful of No. 2 coal seam in Chiyun coal mine, discharge local gas efficiently, the method of drilling gas flow is used to determinate advance borehole effective influence radius of No. 2 coal seam, and the method of outburst index is used to define the result of determination finally. The result shows that the way of using the methods of drilling gas flow and outburst index comprehensively to determinate advance borehole effective influence radius will make the data more pertinence for design and operability for construction, and will apply practicability direct to the No. 2 coal seam gas treatment in Chiyun coal mine.
