Abstract: Around the unbalance of air pressure appeared in two mining areas during deep mining of Sanshandao Gold Mine，such techniques as the remote centralized control technology of ventilation systems，the fan inverter technology and the underground ventilation parameter monitoring technology were adopted to realize the remote centralized monitor on the fans distributed in each underground fan station and the airflow pressure parameters at the main ventilation roadway.Based on the total amount of air meeting the design requirements，the air flow at each run-through was reduced from 90.60 m3/s to 13.60 m3/s through comprehensively regulating the frequency of fans at main return air fan station in two mining areas.By this method，cross pollution of the air between the two mines can be effectively alleviated.The stable running of the remote centralized ventilation monitoring system starts a solid step forward in accelerating the process of building the digital mine digitization.
