The invention discloses a high-efficiency energy-saving mine multi-stage fan
station ventilation monitoring
technology system. Intake fan stations (1) are arranged in the intake sections of a mine, return fan stations (2) are arranged in the return air sections, air consumption fan stations (3) are arranged in the air consumption sections, and a ground main mine monitoring room (4) is arranged on the ground surface of the mine. A multi-stage fan
station ventilation network calculation program is developed to carry out numerical calculation on the ventilation parameters of the ventilation
system, such as ventilation resistance, the blowing rates of fans of the fan stations, wind pressure, efficiency and total power; the number of fan
station stages and the locations of the fan stations are determined; fan models are chosen, and the blowing rates are regulated; and a remote centralized multi-stage fan station
monitoring system and an underground on-line atmospheric environment
monitoring system are constructed. The pressure-equalizing ventilation of each mine ventilation network section can be realized, air leakage is reduced, the starting and stopping of the fans of the intake fan stations, the return fan stations and the air consumption fan stations in the mine can be remotely controlled, the variable-frequency speed regulation of the fans is realized, the
system can perform inverted ventilation, parameters, such as the operating states of the fans, the blowing rates and wind pressure of the fans, motor bearing temperatures and power factors, can be monitored in real time, and the underground ventilation environment can be monitored in real time and on line.
