In order to effectively solve the problems of low intelligence level,widespread"one wind blowing"phenomenon,and low ventilation efficiency of local ventilation fans in comprehensive excavation faces,an intelligent local ventilator control system was designed,which adopted fuzzy control and variable frequency speed regulation technology to implement precise control according to the ventilation quality requirements of coal mines.The system application results showed that compared with traditional ventilation systems,the intelligent control system reduced monthly electricity consumption by about 14%,reduced the number of operators by 3,shortened the downtime of faults by nearly 5%,and effectively ensured the safe and stable operation of the ventilation system.
