Abstract: The all factors that affect the mine ventilation system are considerated comprehensively based on the physical composition of ventilation system and the theory of system security.The comprehensive evaluation index sysem of mine ventilation is established that include twenty-five indexs from six aspects of ventilation power,ventilation network,the quality of ventilation,ventilation facitilies,ventilation monitoring and ventilation management.The weighted values of above indexs are obtained by adopting the analytic hierarchy process,besides that,the evaluation model is get to conduct the comprehensive evaluation on the mine ventilation system.

Key words: Mine ventilation system, Index system, Analytic hierarchy process
