【摘要】 运用制定《中国煤炭分类》国家标准所依据的近600个烟煤煤层煤样实测数据,分析了中国不同煤种烟煤镜质组平均最大反射率的分布范围,探讨了烟煤镜质组平均最大反射率与中国煤分类系统之间的关系.研究表明:镜质组反射率与煤种之间的关系较复杂,特别是在中低变质烟煤阶段,相同变质程度煤往往归属于不同煤种,受煤岩组成和还原程度的影响较大.但总的来说,烟煤镜质组反射率与煤种之间的关系规律性明显.更多还原

【Abstract】 Based on analyses of about 600 coal-seam samples used for "Classification of Chinese Coal",the range of mean maximum reflectance of vitrinite(R^o_max,%) of different classes of bituminous coal was presented and the correspondence between them was discussed.The results show that there is distinct relation between reflectance of vitrinite and coal classification,though this correspondence is relatively complex,especially in low-medium metamorphic bituminous stage where coals with same sometimes can be divided into different classes.The regularity is obvious about the correspondence between mean maximum reflectance of vitrinite and classification of coals.更多还原
