摘要
分析了以往工作面上隅角瓦斯治理情况,通过在低瓦斯矿井采用移动式瓦斯抽放泵对采空区瓦斯进行抽放,以及利用顶板走向长钻孔治理上隅角瓦斯,解决了回采工作面上隅角瓦斯超限问题,确保了矿井安全生产,对低瓦斯矿井工作面上隅角瓦斯综合治理工作具有一定的参考作用。
This article analysed previous gas control conditions in working face upper corner,gas in goaf was drainaged by using mobile gas drainage pump in low gas mine. The problem of gas over-limit was solved with the application of gas drainage from long holes along roof strike in the working face upper corner, and the coal mine safety production was ensured. All these have certain reference value to comprehensive gas control in the working face upper Corner.
