任家庄煤矿3~#煤层瓦斯赋存规律研究
|
摘要
运用瓦斯地质学的方法,依据勘探、建井及生产期间瓦斯参数测试结果,通过各地质因素与瓦斯赋存的关系统计分析,对任家庄煤矿3~#煤层瓦斯赋存规律进行探讨。结果表明:3~#煤层瓦斯含量整体较低且分布不均衡;成煤期后的地质演化是导致3~#煤层瓦斯含量普遍较低,瓦斯风化带深度较大的决定性因素;三道沟背斜与上覆岩层特殊的岩性组合,使得瓦斯在背斜轴部部位聚集,形成瓦斯风化带中的相对高瓦斯区域。
According to previous data and experimental results,the coalbed gas occurrence regularity of No. 3 coal seam in Renjiazhuang coal mine is discussed using the method of gas geology. The results show that the gas content is generally low and unbalanced in Renjiazhuang coalfiled;the geological evolution is direct reason of the gas distribution; the gas accumulated in the high spot of Sandaogou anticline because of the special lithology combinaton,and elatively high gas area existed in the gas weathering zone.
