Abstract Ventilation resistance measurement of Xing’an Mine was taken as example, ventilation resistance measurement program was settled, ventilation resistance of air supply section, air supply section and air return section was measured, the efficient wind amount rate was 80.7% by calculation, smaller than least value, combined with the actual situation, the corresponding optimized plan was put forward, the efficient wind amount rate of the mine ventilation system after improvement achieved 89%, with decreased ventilation resistance 300 Pa.
