摘要
根据余吾煤业煤层的赋存情况,基于余吾煤业六条高抽巷的实测数据及其相应工作面的瓦斯治理效果,得出余吾煤业高抽巷的水平合理层位和竖直合理层位。并在余吾煤业N1101工作面进行了现场应用,结果表明,N1101高抽巷层位选择较为合理,瓦斯治理效果较好;回风流瓦斯浓度降低了0.22%,后部刮板机瓦斯浓度降低了0.23%,上隅角瓦斯浓度降低了25.35%。
According to coal seam occurrence in Yuwu Coal Mine, based on the measured data and its corresponding gas control effect in working face of six overlying drainage roadways in Yuwu Coal Mine. , the reasonable level and vertical position were determined, which were applied N1101 working face of Yuwu Coal Mine, field application result showed, the position selection was reasonable, and the gas control effect was favorable, with the gas concentration declined by 0. 22% in return air, 0. 23% at tail end of scraper conveyor, and 25.35% at the upper comer.
