    11-09-2020· Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.

    Coal Type / Lithotype, Kentucky Geological Survey . Coal type is a specific geologic classification based on the general appearance of coal. Most coals have internal layering, called banding. Coal types, and subsets of types, called lithotypes, are based on the presence or absence of banding, and the brightness or dullness of individual bands.
