针对八连城矿井煤层瓦斯含量高、渗透率低复杂地质条件下近距离煤层群开采等特点,提出了立体交叉钻孔以及顶板高位钻孔抽采卸压瓦斯相结合的综合治理方案,构建了复杂地质条件下低渗透高瓦斯煤层群开采瓦斯治理技术体系,有效解决了复杂地质条件下低渗透高瓦斯煤层群开采的工作面瓦斯超限的难题。 In view of the characteristics of high coal seam gas content and low permeability coal seam mining under close geological conditions in the Eerleng Mine, a comprehensive control scheme combining three-dimensional cross-drilling and high-pressure drilling of the roof is proposed, and a complex Under the geological conditions, the gas control technology system of low permeability and high gas coal seams is exploited to effectively solve the problem of methane overrun in the face with high permeability and low gas permeability in complex geological conditions.
