With the continuous advancement of mining to the deep region,good mine ventilation technology is very important for improving the underground working environment and ensuring the safety and efficient mining of underground mines.Based on the engineering background of Eléonore Gold Mine in Canada,this paper adopted the techno-logy of ventilation on demand and the intelligent regulation of mine ventilation network to realize the remote,automatic and closed-loop control of ventilation structures such as main fan,local fan,air door and air window,which improves the utilization rate of air flow and effectively ensures the underground ventilation effect.The field experiment results show that  the ventilation volume and preheating thermal mass consumption in the winter can be reduced by 28.57 %,that the main fan power consumption can be reduced by 66 %,and that local fan power consumption can be reduced by over 90 % by using VOD technology.
