| Abstract: | In order to improve the gas drainage rate of the seam gateway driving face in the thick seam,the paper discussed the principle of the wall drilling high efficient cut off excavation and gas drainage technology.The high efficient cut off technology was applied to the X13014 gas drainage module gateway in Sihe Mine.The test results showed that the gas drainage rate with the wall drilling could reach to over 80% and could be effectively to cut off the gas emission from the coal wall and eliminate the gas conte... |
