Safety Evaluation for Mine Fire Based on Entropy Weight Matter Element Extension

Based on the actual situation of causes and classification of mine fire, we the proposed evaluation index system of mine fire, we introduce the entropy weight method into matter-element theory, establish entropy weight matter element evaluation model of mine fire safety evaluation, and use this model to evaluate 5 coal mines in Guizhou province. The results indicate that the maximum weighted incidence degree of fire safety level in 5 mines is 0.30, 0.16, 0.19, 0.15, 0.29, and the corresponding mine fire safety grade is consistent with the actual situation of the mine, which demonstrates the feasibility of the model.
