Abstract: We present an account of the background, principles and requirements for the classification of Chinese coals. A great deal of experimental work has been carried out on a wide variety of rich coal resources in China. Studies have been conducted on classification parameters for coals with low, medium or high metamorphic degree. Using correlation, discriminant, and cluster analyses, the technique of optimal sections, etc., a large number of test data were computer-analyzed in order to determine classification parameters of coals by type for coal resources in China. Our result is a comprehensive and standardized system of technical classification of Chinese coals.
