Abstract: To counter the problems that the qualitative indices in the coal mine safety management information system are difficult to be quantified and a reasonable evaluation can not be made for the system，in this paper，fuzzy comprehensive evaluation model was used to evaluate the coal mine safety management information system．Analytic hierarchy process was used to determine the weight of each index and a comment set relative to the results was set up; by using the survey method，the fuzzy comprehensive evaluation matrix was obtained，the weight of each index and the corresponding evaluation matrix were synthesized，and the evaluation vector of each index was obtained; each vector was then normalized to get the evaluation results after the index quantization．Empirical analysis was carried out on this model by the safety management information system of a coal mine，and the results showed that the application of the fuzzy comprehensive evaluation model could realize the transformation of the indices from qualitative to quantitative and make the evaluation more scientific and reasonable．
