摘　　要：观音山井田主煤层含气量较高,煤层气资源较为富集,为煤层气开发提供了较为优良的条件。研究表明:井田地质构造简单,主煤层分布稳定,煤级为贫煤,煤层顶底板以泥岩类为主,含煤地层地下水动力微弱,这些条件有利于煤层气的保存;煤层含气量随埋深的增大而规律性增高,表现为单斜控气的典型特征。The main coal bed in Guanyinshan mining field has high gas content. This area is rich in CBM resources. This advantage provides excellent conditions for CBM development. The research shows that, in Guanyinshan mining field ,geological structure is simple, main coal bed with stable distribution, coal rank is lean coal, roof and floor dominated by mudstone, coal- bearing strata with weak hydrodynamic. These conditions are conducive to preservation of coalbed methane. Coal bed gas content increases with depth. Gas is accumulated under control of monocline factors.
