通过实测百灵井田3#煤层瓦斯参数,以瓦斯地质理论为基础,分析了百灵井田瓦斯赋存的控制因素。结果表明:煤变质程度较高,围岩封闭性较好是3#煤层瓦斯富集的根本原因,井田构造和煤层埋深是控制瓦斯含量分布特征的直接因素。
Based on the gas parameters of No.3 coal seam in Bailing Minefield and the gas geological theory, the controlling factors of gas occurrence in Braun minefield are analyzed. The results show that the coal metamorphism is high and the tightness of surrounding rock is the basic reason for the gas enrichment in No.3 coal seam. The minefield structure and coal seam depth are the direct factors controlling the distribution of gas content.
