关于高瓦斯矿井低透气性软煤层抽采技术探究

On the Extraction Technology of Low-permeability Soft Coal Seam of Highly Gassy Mine

为解决中国高瓦斯低透气性煤层瓦斯抽采困难、抽采效率不高的问题,从开采层瓦斯抽采、邻近层瓦斯抽采及采空区瓦斯抽采等3个方面对高瓦斯矿井低透气性软煤层抽采技术进行了探讨,并用一个实例证明了上述抽采技术的有效性,以期为实现瓦斯高效抽排提供一定的借鉴意义。

In order to solve the problems of difficult methane gas extraction and low extraction efficiency of low-permeability soft coal seam of highly gassy mine in China, discusses the extraction technology of low-permeability soft coal seam of highly gassy mine from the aspects of gas extraction of mined bed, adjacent layer and gob, and demonstrates the effectiveness of the extraction technology with an example in order to provide reference for achieving efficient gas pump drainage.
