摘　　要：对贤按煤田合山组钻孔煤样进行了元素分析和煤岩煤质分析,结果表明:贤按煤田合山组煤样整体为特低全水分、特高灰分、高挥发分、特低固定碳煤。有机组分以镜质组为主,含少量惰质组,不含壳质组。镜质组以基质镜质体为主,偶见均质镜质体、结构镜质体。惰质组偶见碎屑惰质体和半丝质体。有机质总量平均值为30.18%。无机组分以黏土为主。合山组煤主要形成于温暖潮湿的海陆过渡相缺氧还原环境。Element analysis and coal petrology and coal quality analysis are carried out on the drill coal samples of Heshan Formation in Xian’an Coalfield,the results show that:The coal sample of Heshan Formation in Xian’an coalfield is extremely low total moisture,extremely high ash,high volatile content and extremely low fixed carbon coal.The mainly organic component is vitrinite,containing a small amount of inertinite and no chitinite.Vitrinite is dominated by matrix vitrinite,with homogeneous vitrinite and structural vitrinite occasionally seen.Clastic inertinite and semifusinite are occasionally seen in inertinite.The mean value of total organic matter is 30.18%.The inorganic component is mainly clay.The coal of Heshan Formation was mainly formed in the anoxic reduction environment of the warm and humid marine and continental transitional phase.
