| Abstract: | Longwall 17258 of Zhangji Coal Mine is island- like. In order to prevent spontaneous combustion ac- cidents in mining process, bound pipe was pre -settled in air return way to sample gases for type JSG -7 moni- toring system to detect gases in goal, and to determine change of three zones distribution in goal to ensure safety in mining orocess of longwall 17258. |
