摘　　要：作者对所划分出的“三种四类”煤型的煤质特征进行了深入研究，论述了由不同煤相决定的不同煤型制约着不同煤质的观点。研究认为：Ⅰ煤型煤为较好的低温干馏炼油煤和非常好的烃源岩；Ⅱ煤型煤为良好的炼焦煤或炼焦配煤和良好的烃源岩；Ⅲ煤型煤为较好～较差的炼焦配煤和较好～较差的烃源岩。通过揭示不同煤型所特有的煤质特征，阐明了煤型与煤质之间的成因联系，进一步论证了“沉煤环境（煤相）—成煤类型（煤型）煤质特征—（煤质）”这一概略成因模型的客观存在。Author discussed on the viewpoint of the different type of coal-forming which decided by the different coal facies, influenced the coal quality. The result shows that Ⅰ coal-types coal will be a better tar-forming coal and source rocks, and Ⅱ coal-types coal will be a good caking and hydrocarbon source-rocks, and Ⅲ coal-types will be a good or poor caking blends and source-rocks. By a thorough study on the properties about coal-quality of different coal-types coal, expounded the internal genetic ralations between coal-types and coal-quality. And take further step to explain the real existence the rough genetic model of “the sedimentary environment—type of coal-forming—characteristic of coal quality”.
