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%。

Abstract: Abstract：according to more than yuwu coal seam occurrence of coal seam, based on more than yuwu coal six high alley pumping of the measured data and its corresponding working face gas control effect, it is concluded that more than our coal alley pumping high level reasonable horizon, based on a reasonable level at the same time horizon and the corresponding working face gas control effect, it is concluded that more than my high coal alley pumping reasonable vertical horizon. In the N1101 working face, the field application has been carried out, and the effect of gas control has been achieved.
