Abstract: The model is built through the improved analytic hierarchy process and comprehensive fuzzy evaluation based on three kinds of hazard theory of gas in coal mine so as to assessment the gas explosion accident in coal mine.In order to test the effect of the model,so the assessment is carried on for the five roadways of a coal mine in Shanxi. The experimental results indicated that the performance of the model is better than the tranditional ones and more similar to the real situations. According to the theoretical analysis and experimental results,the assessment model in this paper is capable to deal the actual situation.

Key words: Assessment model, Gas explosion, Improved AHP, Comprehensive fuzzy evaluation
