摘　　要：本文是《实用煤相学》研究的另一篇论文，对组成不同煤相（Ⅰ１、Ⅰ２、Ⅱ和Ⅲ）的煤的类型进行了深入分析，论述了不同环境（煤相）决定了不同的成煤类型的观点。通过对不同煤型煤的显微组分（类脂组、镜质组和无机组分）组成和镜质组特征（荧光强度和反射率）的深入研究，划分出与四种煤相相对应的四种基本的类型：即强还原型腐泥煤或腐殖腐泥煤（Ⅰ１型）、强还原型腐泥腐殖煤或腐殖煤（Ⅰ２型）、较强还原型腐殖煤（Ⅱ型）和较弱还原型腐殖煤（Ⅲ型）。从而阐述了煤相与煤型之间的内在成因联系。为进一步表述“沉煤环境（煤相）—成煤类型（煤型）—煤质特征（煤质）”这一概略成因模型奠定了基础。this psper is another paper about《Practice coal facieology》. Made a thorough analysis on the coal-types which constituted the different coal facies(Ⅰ 1,Ⅰ 2,ⅡandⅢ),Author discussed on the viewpoint of the differdnt environmdnt(coal facies) decided the differdnt type of coal-forming.By a thorough study on the components of maceral(liptinite,vitrinite and inorganic components)and the properties of vitrinite,(relative fluorescence intensity and reflectances)for coal of differdnt coal-types,The coal-types be classified as four basic type corresponding four basic coal-facies,they are the strong reductibility sapropelic or humic-sapropelic coal (Ⅰ 1 type),the strong reductibility sapropelic-humic or humic coal(Ⅰ 2 type),the relatively strong reductibility humic coal(Ⅱ type)and the weaker reductibility humic coal(Ⅲ type),And expounded the internal genetic relations between coal-facies and coal-types,And this lay a foundation for taking further step to explain the rough genetic model of 'the sedimentary environment——type of coal-forming—characteristic of coal quality'.
