摘要
为了确保工作面高抽巷设计的合理性,本文以汾西矿业集团贺西煤矿3316工作面高抽巷设计为背景,通过阐述高抽巷瓦斯抽放技术原理,分析影响高抽巷瓦斯抽放效果的主要因素,并通过计算确定高抽巷合理层位及高抽巷的施工注意事项和管路的安装和闭墙的布置,实践证明设计布置的高抽巷完全可以满足工作面上隅角瓦斯治理要求。
In order to ensure the rationality of the design of working face high alley pumping, this paper takes the high drainage design of 3316 working face of Hexi Mine, Fenxi Mining Group as the background, expounds high alley pumping gas drainage technology principle, analyzes the influence factors of high gas drainage pump lane, and determines the reasonable high drainage layer and high alley pumping construction considerations and pipeline installation and layout of the closed wall, through the calculate. Working face production practice shows that high alley pumping can completely satisfy the work top corner gas management.
