摘要
通过冲孔释放了煤体内的潜能,排放了大量瓦斯,使煤层透气性明显增加,抽采半径增大,抽采效果、消突效果得到显著提高,突出区煤巷单进水平明显提升。
By punching, the coal body＇s potential is released, a large number of gas is exhausted, so that the coal seam permeability is increased significantly, drainage radius are increased, the drainage effect and preventing outburst effect have been significantly improved, and the outburst area roadway single-entry level is improved significantly.
