| Abstract: | 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. |
