摘　　要：八道江矿区位于浑江煤田西段,主要开采石炭—二叠纪煤层,煤类复杂。根据矿区地质资料,论述了地层的含煤性,并对工业分析和元素分析的结果进行了讨论。分析认为该矿区以瘦煤为主,由于火成岩影响部分变质为贫煤、无烟煤和天然焦;煤的黏结性好,结渣性轻微,是很好的炼焦用煤;煤发热量为21.31～23.88MJ/kg,属于中高热值煤,也可用做动力用煤。该区原煤洁净等级为三级,精煤洁净等级为二级。The Badaojiang mine area is situated in westem sector of the Hunjiang coalfield, mainly mining the Permo-Carboniferous coal seams with complex coal ranks. According to geological data of the mine area, discussed coal-bearing property of strata, and results of proximate and ultimate analyses. Considered that the coal rank in the mine area is mainly lean coal, and partly metamorphosed into meager coal, anthracite and natural coke because of igneous rock intrusion. Coals have good caking and slight clinkering properties, thus very good for coking. Coal calorific value is 21.31 ~23.88MJ/kg, belongs medium to high thermal value coal, can be used as power coal. Raw coal degree of lustration is in third level, while cleaned coal second.
