针对工作面瓦斯涌出量大,抽采量小,预抽效果差等问题,提出了利用交叉钻孔预抽瓦斯。介绍交叉钻孔、平行顺层密集钻孔2种不同钻孔布置方式的强化预抽原理。在现场进行试验,分别在同一工作面划分3个区域布置立体交叉钻孔、平面交叉钻孔和平行顺层密集钻孔3种方式的钻孔,考察各方式的抽采参数以及工作面在进入各试验钻孔区域后的瓦斯涌出量情况,结果显示立体交叉钻孔抽采最佳。 Aiming at the problems of large gas emission from working face, small extraction volume and poor pre-pumping efficiency, the paper proposes to use pre-drainage gas by cross-drilling. This paper introduces the principle of enhanced pre-pumping of two different drilling layouts of cross drilling and parallel bedding drilling. The experiment was carried out in the field. Three cross-boreholes, three-dimensional cross-boreholes and three parallel boreholes were drilled in the same working face, and the drilling parameters of each mode and the working face Gas emission after drilling in each area, the results show that the best three-dimensional cross-hole drilling.
