摘要
为解决在大采高采煤工作面推进过程中因采空区瓦斯涌出造成工作面及上隅角发生瓦斯超限问题,赵庄矿通过采用高抽巷抽采瓦斯的方法,在采煤工作面上覆岩层实施了一条顶板走向高抽巷,并对层位布置、抽采效果等进行了考察。结果表明:采用高抽巷抽采瓦斯的方法实现了采空区瓦斯的有效抽采,成功解决了采煤工作面及上隅角瓦斯超限的问题,确保了矿井安全高效生产。
To solve gas emission exceeding normal value on working face and upper corners caused by gas emission in gob in the advancing of large-mining-height working face, high drainage tunnel method was used in Zhaozhuang Mine. A high drainage tunnel along roof strike was constructed on the overlying strata on the mining face. In addition, the strata position and drainage effect were studied. The results show that the high drainage tunnel method could realize the effective drainage of gas in gob and successfully solve the problem of gas emission, which could guarantee the safe and efficient production in mines.
