Abstract：Based on the characteristic analysis on mine ventilation system,this paper establishes a multi-hi-erarchy index system of evaluation factors for ventilation system state,and according to the importance of the analytic hierarchy process analysed and made certain 20 evaluation indexes value and the coherence verifica-tion are made. A result of safety evaluation was educed according to the rules of credible recognition after an unascertained measure model was constructed,and according to the importance unascertained measure values of all evaluation indexes were calculated. We made a safety evaluation to the ventilation system of a mine and the result of the safety evaluation is the same as the safety status quo of the mine. So the results show that the safety evaluation method which is based on the unascertained measure theory and the analytic hierarchy process is feasible in this paper.
