采空区瓦斯埋管抽采技术应用与分析
|
摘要
针对采空区瓦斯突然涌出对生产设备和作业人员的危害,以8208工作面为工程背景,由于现有的抽采方法不能满足实际要求,故提出了采空区埋管法抽采瓦斯工艺,并通过数值模拟对采空区埋管抽采效果进行分析,从而得出最优的抽采布管方式。
In view of the sudden emergence of gas in the goaf to the production equipment and workers, the 8208 working face is the engineering background. Because the existing extraction method can not meet the actual requirements, the gas extraction process of the goaf is proposed. And through the numerical simulation to analyze the extraction effect of the buried pipe in the goaf, so as to obtain the optimal method of pumping and pipe.
