作者在分析了我国各地区、各成煤时代的主要可采煤层的大量样品的煤岩特征、化学工艺性质和沉积环境之间的相互关系之后,提出中国煤存在两种成因系列的观点。作者认为,只有根据不同成因系列,才能用煤岩指标预测煤的化学工艺性质。反射率R°_(max)、可熔组分总量∑r和粘结指数G_(RI)是拟订烟煤的成因—工业分类较好的指标。这样的分类将促进煤炭资源的合理利用。
After analyzing the correlations between coal-rock characteristics, chemical process properties and sedimentary environment in a large number of samples of major recoverable coal seams in all regions of China and coal-forming age, the authors put forward the opinion that there are two kinds of causal series in Chinese coal. The author believes that only based on different series of causes in order to predict coal chemical indicators of the nature of the process. The reflectivity R ° _ (max), the total amount of fusible components Σr and the adhesion index G_ (RI) are the causes for the development of bituminous coal - a good indicator of industrial classification. Such classification will promote the rational use of coal resources.
