Ventilation of tunneling face is an important part of mine ventilation system，which is of great signi-ficance for guaranteeing the health and life safety of workers.However，the special plateau environment with low pressure and low oxygen has put forward higher requirements for ventilation effect.According to the special environmental requirements of high altitude metal mine and based on analytic network process，11 evaluation indexes were established from three aspects of safety benefit，economic benefit and technical benefit.There is a complex interaction between the evaluation indexes of the ventilation effect of the heading face.The correlation of the evaluation indexes was obtained through group discussion among 12 researchers in the field of mine ventilation.Thus the network structure of ventilation effect evaluation index of heading face was established and the final evaluation system was formed.ANP method involves many elements，the calculation process is complex and the calculation is large.According to the analysis of the ventilation effect evaluation index of the tunneling face of the high-altitude mine and the result of correlation relationship construction，the ANP model diagram of ventilation effect evaluation of the tunneling face was established in the super decision software.The comprehensive weight of three ventilation modes and the global weight of each evaluation index were calculated to select the best ventilation method.This evaluation system was applied to a metal mine at an altitude of 3 400 m in Yunnan.Ten people，including experts in mine ventilation engineering and on-the-job mine ventilation technicians，were invited to fill in the pairwise comparison judgment matrix questionnaire.By comparing the importance of the two evaluation indexes，the judgment matrix was established，and the super decision software was used for relevant calculation.The results show that the comprehensive weight of far-pressing-near-suction ventilation mode ventilation mode is 46.16%，and its ventilation effect is the best.The global weight of “oxygen supply effect” is 20.08%，which is the most important evaluation index.The oxygen supply effect should be taken into account when choosing the ventilation mode of mining face at high altitude.It is proved by practice that the conclusions obtained by the evaluation system are in line with the actual safety of mines，and can point out the main factors to evaluate the ventilation effect of mines.
