Abstract: It is of great significance to correctly identify the type of coal (anthracite, bituminous and lignite) for the research and prediction of coal quality, rational development, scientific and effective utilization of coal resources, and safety management and trade of coal enterprise. The article establishes a fuzzy evaluation classification model of coal. In the modeling process, it considers a variety of factors that affect the classification of coal, builds standard classification criteria based on the original sample values, and calculates test results and the predicted results by Matlab programming. Examples show that the fuzzy comprehensive evaluation classification model has high accuracy and reliability in the prediction of coal classification.
