移动抽放结合降段煤垛治理工作面瓦斯

Using mobile drainage and lower-sect coal stack to control gas of working face

借鉴回采工作面瓦斯治理的各种方法,结合七台河煤业集团桃山矿427回采面的具体情况及瓦斯涌出实际规律,在实践中摸索出了一种新的治理回采工作面瓦斯的方法——利用降段煤垛与移动抽放相结合的方法,并在桃山矿应用,实际测试数据标明,瓦斯抽防效果良好。由此得出,降段煤垛与移动抽放相结合的方法是高瓦斯矿井回采工作面瓦斯治理的有效方法。

A variety of methods about gas control in the working face are used for reference. According to the specific conditions and actual gas emission law of 427 working face of Taoshan mine, Qitaihe Mining Group, a new method to control gas of working face, i.e. a control method that unites lower-sect coal stack method and mobile drainage method is obtained in practice, and the method is applied to Taoshan mine. The actual data show that the gas drainage effect is good. We can conclude that the method that unites lower-sect coal stack method and mobile drainage method is an effective measure in the control of gas in the working face of high gas mine.
