摘要
论述了在高瓦斯矿井,井下钻孔抽采是矿井瓦斯治理的基本方法,但该方法存在瓦斯治理时间和空间局限性的问题。地面抽采方法可以对矿井规划采区进行有效的抽采,摆脱井下抽采的局限性,从而解决井下瓦斯治理存在的问题。
In high gas mine, downhole drilling drainage is the basic method of gas control in the mine, but this method has the problems of the gas control time and space limitation. The ground extraction method can effectively drainage to the planning area of coal mine, get rid of the limitations of the underground extraction, thus solves the existing problems of underground gas control.
