| Abstract: | In order to solve the problem that the sealing effect of the existing gas drainage drilling hole sealing technology is poor,which leads to the poor gas drainage effect,a new key technology of gas drainage hole sealing is studied and put forward,and the field test of gas drainage is carried out in the 13091 roadway of Hudi Coal Industry.The test results show that the gas drainage concentration and gas extraction quantity have been greatly improved after the application of this technology,remarkable gas drainage effect and economic and social benefits have been obtained. |
