| 摘 要： | 根据实测资料及前人研究成果,分析了二道岭矿区煤变质程度、区域构造、煤层埋深和顶底板岩性对煤层含气量的影响作用。研究认为：高异常地热场是导致该区域含气量偏高的主要原因;构造和顶底板对煤层气控气作用明显,二道岭向斜核部煤层的含气量高达24m3/t,矿区顶、底板多为泥岩及粉砂岩组成,利于煤层气的储存;煤层埋深与含气量之间的相关性密切,根据两者关系建立的数学模型,可以预测研究区深部一定范围内的煤层含气量。

| Abstract: | Based on the measured data in Erdaoling mine area,where the gas content is high,the paper analyzed the influence factors from the aspects of metamorphic degree,regional structure and burial depth,as well as the roof and floor lithologic characters.The authors have found that the main reason to cause high gas content is the high anomalous geothermal field,and the gas content is obviously controlled by regional structure and burial depth.Because the depth of coal seam is well correlated with the gas content,t... |
