| Abstract: | In order to measure the influence radius of the borehole drilled along seam and guide the mines’ work of gas drainage and eliminating outburst,gas flow of the borehole was taken as the investigation index.A measurement study was conducted in No.15 coal seam of Si Jiazhuang coal mine.The test results showed that the gas flow method would be easy to be investigated,would quickly and accurately determine the influence radius of the borehole drilled along seam in extracting seam. |
