摘要
通过分析贺西煤矿高瓦斯矿井近距离煤层间岩层和瓦斯在煤与瓦斯共采过程中的移动规律,研究采空区及上覆岩层、高浓度瓦斯环形裂隙圈参数,以及近距离煤层间煤与瓦斯共采前后的煤层瓦斯分布规律,从而掌握瓦斯赋存状态,制定瓦斯综合抽采方案,检验瓦斯治理效果,确保矿井安全生产。
Based on the displacement law of strata and gas in the process of coal mining and gas extraction in high gassy mine, the paper studies the fissured circle of high concentration gas in goaf and overlying strata. The gas distribution laws before and after the coal mining and gas extraction are also analyzed to obtain gas occurrence, make a comprehensive extraction plan for gas, check gas control effects, and guarantee the safe production in mines.
