Abstract: Aiming at the ambiguity and randomness of the indicators in the comprehensive evaluation of the safety of the mine ventilation system, a two-level fuzzy comprehensive evaluation model of safety is established. In this paper, to calculate the indicators which have enhanced the objectivity and scientific of the safety evaluation of the mine ventilation system, network analytic method (ANP) is used. By utilising this ANP method, the obtained results indicated that the safety level of the mine was only 'general safety'. Through single-factor evaluation and analysis of the weights of various indicators, the system can be based on the employees' physical fatigue (A3), employees' attendance (A7), volume fraction of gas and toxic gas (C3), dust mass concentration (C5), air volume supply-demand ratio (C7), ventilation system hole volume ratio (C8) and regular inspection (B1) to improve the safety of the mine ventilation system.
