摘　　要：为了使煤层瓦斯抽放钻孔布置更加合理、科学和有针对性,采用钻孔测试法,井下直接测定煤层原始瓦斯含量指标以及钻孔瓦斯动态抽采量指标,使用煤层瓦斯抽采率这一抽采有效性指标,对西马煤矿12#、13#这2个煤层的瓦斯抽采半径进行测定研究,确定该矿12#煤层和13#煤层的瓦斯有效抽采半径,保证了矿井安全有效开采。In order to make coal seam gas drainage drilling layout more reasonable,scientific and targeted.By using the borehole test method,directly measure the original gas content index of the coal seam and the dynamic gas extraction index of the borehole.By using the extraction efficiency index of coal seam gas extraction rate,for the No.12 and No.13 of Xima coal mine,measure the gas drainage radius of the coal seam to determine the effective gas drainage radius of the No.12 coal seam and No.13 coal seam of the mine thus to ensure the safety and effective mining of the mine.
