瓦斯突出矿井预抽巷布置方法

Layout Method of Pre Drainage Lane in Gas Outburst Mine

本文针对东曲煤矿+860水平九采区瓦斯预抽巷巷道的两种布置方案,在工作面低抽巷沿不同层位进行布置以及不同施工方式、抽采进度及难易程度、所产生的经济、回采衔接效益等各方面,进行了比较分析说明,最终采用方案一即瓦斯预抽巷道布置在煤层内为最佳施工方案。

In this paper, aiming at the two layout schemes of gas pre draining laneway in the ＋860 level nine mining area of Dong Qu Coal Mine, this paper compares and analyzes the layout of the roadway along different layers along the low level of working face, the different construction methods, the pumping progress and the difficulty degree, the economy and the benefit of the recovery. Finally, the scheme is adopted. That is, gas pre drainage roadway layout in the coal seam is the best construction plan.
