Evaluation of Coal Mine Safety Management Based on Fuzzy Mathematics

Aiming at the problem that the coal mine is restricted by various risk factors and most of the risk factors have the characteristics of fuzziness in the production process，a comprehensive safety evaluation model for the second rate coal mines was built through the summary and classification of all factors and by using the method of fuzzy mathematics，taking Pingdingshan No．13 Mine as an example，safety evaluation was carried out on the risk of gas outburst，and the results showed that the model was practical and operable．
