摘要
艾维尔沟矿区的煤层气赋存受到煤层埋藏深度、构造演化、煤变质程度、水文地质条件等因素的影响。从整体上看西部地区煤层埋藏较深,煤质变质程度高,东部逆冲断层发育,对煤层气有较好的封存作用,在开采过程中,由于矿区受顶板岩性、水文等地质条件的影响,煤层气含量较高。
The study shows that coalbed methane accumulation in the Aiwiergou mine area is affected by factors such as coal seal depth,geological structure evolution,coal metamorphic degree,and hydrogeological conditions.Overall,the western part of the coal seam has a greater depth,higher coal metamorphic degree,and the eastern part has an uplifted fault,which has a good sealing effect on coalbed methane.
