摘要
为解决山西安泽玉华煤矿采煤工作面风排瓦斯量大的问题,实施应用了本煤层瓦斯抽采、采空区瓦斯抽采以及高位定向长钻孔裂隙带瓦斯抽采等综合瓦斯抽采技术,大大提高了瓦斯抽采效果,彻底解决了采煤工作面回风流瓦斯浓度偏高的问题,为矿井安全生产提供了安全保障,为高瓦斯矿井瓦斯治理提供了有益借鉴。
In order to solve the problem of large gas discharge from the coal mining face of Yuhua Coal Mine in Anze,Shanxi,comprehensive gas extraction technologies such as gas extraction from the coal seam,gas extraction from the goaf,and gas extraction from high directional long drilling fracture zones were implemented and applied,greatly improving the gas extraction effect and solving the problem of high gas concentration in the return air flow of the coal mining face,providing safety assurance for mine safety production and useful reference for gas control in high gas mines.
