Abstract： In order to improve the performance of ventilation system in Sitai Mine and realize safe and efficient mining in coal mines, combined with field measurement and VNT network solution, aiming at the problems of low effective air volume rate, serious air leakage, unreasonable resistance distribution and excess capacity of main fans, the optimization measures are put forward. The reinforcement and transformation of multiple air doors are adopted, and the main fan No.2 operating angle +7.5° is replaced by No.1 fan +5°. After the transformation, the required air volume of each wind site in Sitai Mine meets the requirements, and the total ventilation resistance is reduced from 2 984.53 Pa to 2 432.10 Pa, which reduces the power consumption of the fan.
