Mine gas system largely determines the safety of coal mine. Therefore, it is of great practical significance to evaluate the safety of mine gas system accurately. This study aims to establish a scientific gas evaluation system and improve the safety of mine. In this paper, the safety of mine gas system is evaluated accurately; besides, the selecting method of evaluation index system, the construction method of mathematical model and the evaluation grade are determined according to the actual situation. The safety evaluation system of the gas system is established by using the analytic hierarchy process; the index weight is calculated by using the maximum eigenvalue. The consistency test of indexes is also passed. Finally, the mathematical model is verified by an example. The result shows that the fuzzy mathematical model can be used to evaluate the safety of the gas system in a better way, thus improving the safety factor of the whole mine.
