| 摘 要： | 本文以新元矿3107工作面为工程背景,采用数值计算软件对Y型通风情况下瓦斯运移规律进行研究,可知在沿空留巷密闭墙及其上部空间内有瓦斯积聚现象产生,基于此提出了采前钻孔进行瓦斯抽采、高位钻孔瓦斯抽采及采空区埋管抽放瓦斯的综合治理措施,现场应用效果表明,工作面回采过程中上隅角、采空区、回风流中瓦斯含量均实现明显降低,实现了工作面安全高效回采及矿井安全。

| Abstract: | In this paper,the working surface of the New Dollar Mine 3107 is the engineering background,the use of numerical calculation software to study the law of gas transport under Y-type ventilation,it can be seen that there is gas accumulation in the closed wall along the empty lane and its upper space,based on this proposed pre-drilling for gas extraction,The comprehensive management measures of high-bore gas extraction and extraction of buried pipe discharge gas in the high-bore gas extraction area show that the gas content in the upper angle,the hollowing area and the backwind flow of the working surface is significantly reduced,and the safety of the work surface is realized and the mine safety is realized. |
