工作面上隅角瓦斯超限的高抽巷布置方式优选研究

Study on the preferred arrangement of high drainage roadway with gas exceeding at the upper corner of working face

为了解决采空区瓦斯浓度大的问题,本文以镇城底矿22208工作面为研究背景,利用数值模拟软件对高抽巷布置的参数进行研究。通过分析表明,高抽巷布置在距离巷道底板38 m,距离回风巷30 m的位置时,瓦斯抽采效果最佳,为矿井的安全生产做出一定的贡献。

In order to solve the problem of large gas concentration in the mining area,22208 working face of Zhenchengdi Mine was taken as the research background,and numerical simulation software was adopted to study the parameters of high drainage roadway arrangement,through the analysis,it showed that at the position of 38 m from the bottom of the roadway and 30 m from the air return roadway had the best gas extraction effect,which made a certain contribution to the safe mining.
