摘要
石港煤矿15号煤层为煤与瓦斯突出煤层,为了指导石港煤矿消突工作面顺层抽放钻孔的合理布置,采用瓦斯流量法测量了石港煤矿15号煤层顺层钻孔抽放影响半径。结果表明:测试本煤层顺层钻孔的抽放影响半径时,瓦斯流量法是一种便捷、准确的方法。
No.15 coal seam in Shigang Coal Mine is a coal seam with coal and gas outburst danger.To guide reasonable arrangement of borehole drilled along seam on the eliminating outburst working face of Shigang Coal Mine,the drainage influence radius of borehole drilled along seam was investigated through the gas flow method in No.15 coal seam of Shigang Coal Mine.Test results show that,the gas flow method is a quick and accurate method in determining the influence radius of the borehole drilled along seam.
