摘要
为加强谢桥煤矿11426综采工作面瓦斯治理,在该工作面实施Y型通风的基础上,采用穿层钻孔抽采、工作面顺层钻孔抽采、采空区埋管抽采、底抽巷回风立眼封闭抽采相结合的瓦斯抽采方法,对各种方式的瓦斯抽采效果进行统计与分析。实践表明,采取综合的抽采方式对工作面瓦斯进行治理,效果较为理想,为矿井安全生产提供了有力保障。
In order to strengthen gas control in 11426 fully mechanized mining face of Xieqiao Coal Mine,on the basis of Y-type ventilation in this face,gas extraction methods combining cross-layer borehole extraction,borehole extraction along the working face,buried pipe extraction in goaf,air extraction in bottom drainage roadway and closed-off extraction in vertical hole are adopted to make statistics on the effect of gas extraction of various modes.Practice shows that comprehensive gas extraction method is effective in gas control at working face,which provides a strong guarantee for mine safety production.
