Abstract

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.

Description

technical field [0001] The invention relates to an underground mine ventilation technology, in particular to a mine multi-stage ventilation system technology, which can be widely used in underground mine ventilation systems. Background technique [0002] Mine multi-level machine station ventilation technology is to use the principle of wind pressure balance to implement pressure equalization ventilation on the mine ventilation system. Regulating (starting and stopping of fan, fan running speed), to achieve the balance of wind pressure in each branch air path, the wind pressure at the two ends of each leakage air path is equal, that is, the external air leakage point keeps the differential pressure at zero, and the internal air leakage point keeps the wind pressure equal . [0003] Compared with the large main fan ventilation system, the multi-stage machine station ventilation system can make the ventilation pressure evenly distributed, reduce the air leakage, increase the e...
