摘要
大兴煤矿Sv712综采工作面回采期间绝对瓦斯涌出量曾高达120m3/min,通过分析回采期间瓦斯的来源,采取回顺外错式平位尾巷内打钻、地面垂直钻孔、采空区埋管、顶板瓦斯道等抽放瓦斯方法,同时合理调整配风量等综合治理瓦斯措施,取得了较理想的效果。
The gas discharge volume of Daxing Coal Mine Sv712 fully mechanized face during working time had reached 120 m^3/min. The gas source during stoping work time is analyzd. The method of drawing and giving out gas of returning in the direction and outside interlocked and jagged level place tail tunnel inside drilled hole, gob area buried pipes and roof gas road is applied. At the same time, the way of synthetic administration gas on wind volume is adjusted. The good effect is obtained.
