Abstract: The underground mining fields of Fushan gold mine 61# vein run through the goaf，so the air leakage passage can not be controlled by filling or sealing.The main fan air inlet sides of the exhaust ventilation system are in the zone of negative pressure，which leads to increased volume of air leakage in gob area，the low air efficiency of the system.Through the analysis of characteristics of air leakage in mine goaf，the underground goaf air leakage control is studies by establishing the dynamic model of the ventilation system，optimizing the ventilation network，and adjusting the wind volume and pressure.The fan FM technology remote control is additionally arranged in the operating frequency of the air ventilation equipment side，changing air leakage channel at both ends of the pressure difference，to realize the change of 61# ore vein of air leakage and air leakage quantity to and solve the air leakage problem.Research shows that the pressure balance and centralized remote control technology can effectively control the Fushan gold mine out of the ventilation system air leakage in gob area and ensure the reliability and stability of mine ventilation system.
