高位瓦斯抽放巷技术在彬长矿区的应用

Application of High Level Gas Drainage Roadway Technology in Binchang Mining Area

针对高瓦斯矿井低透气性煤层采煤工作面瓦斯危害情况,采用顶板岩石走向高位瓦斯抽放巷治理技术,分析确定了高位瓦斯抽放巷的合理布置参数。现场实践证明,该项技术适合彬长矿区采煤工作面现场条件,保证了采煤工作面的安全回采。

Aiming at the gas hazardous situation of the coal face in the low-permeability coal seam of the high-gas mine,the reasonable layout parameters of the high-position gas-drawing roadway are analyzed by using the top-plate rock to the high-position gas-pumping and drainage-lane treatment technology.The field practice shows that the technology is suitable for the on-site condition of the coal face in Binchang mining area,and ensures the safe mining of the working face.
