中文摘要：
青山矿区煤层埋藏适中,可采煤层层数多、煤层总厚度大;煤体结构较为完整,渗透性较好,煤层气保存条件良好,含气量高,资源丰度大。通过对研究区内的水文地质与煤层含气性的耦合分析,对区内水文地质控气特征进行了研究。结果表明：青山矿区为向斜型水力封闭的含煤盆地,水力封闭和水力封堵是造成区内煤层气富集的主要原因;不同岩性及其组合之间水力联系微弱,造成了多层叠置独立含气系统。
英文摘要：
For coal-bed of Qingshan mining area,the buried depth is moderate,the recoverable layer number is multiple,the total thickness is large,the coal structure is relatively complete,the permeability is relatively good,the preservation condition is well,the CBM content is high.Through Hydrogeological and coincident analyses of CBM-bearing properties in research area,we divided the hydrogeological controlled properties of CBM,and then find： Qingshan mining area is a coal basin of water trap syncline.Hydraulic closure and plugging cause the CBM enrich-ment;Hydraulic closure between different Rock cause the multiplayer superposition with independent CBM-bearing System.
