高瓦斯矿井处理采空区瓦斯泄漏问题的实践与认识

Practice and recoganition on the question of dealing with gas - leaking in goaf in high gas mine

介绍了前岭煤矿的煤层及瓦斯的赋存情况,回采巷道的布置情况。该矿413机巷后路瓦斯超限是采空区瓦斯通过联络巷泄漏所致。通过瓦斯治理过程的实践效果分析认识到,改变封闭墙施工工艺是治理瓦斯泄漏问题的有效手段之一。

The storage situation of coal and gas, and the actual mining road arrangement in Qianling Coal Mine are introduced. Gas overflowed in wood road 413 of this mine is through the link - roadway caused by goaf gas discrarging. The experiment shows that one of the effective method of controlling gas - leaking is the technology of altering the seal - wall process.
