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 machine station ventilation system technology, which can be widely used in underground mine mining. Background technique [0002] The ventilation technology of mine multi-stage turbine stations uses the principle of air pressure balance to implement pressure equalization ventilation in the mine ventilation system. Its basic characteristics are: under the premise of maintaining the required air volume of each wind path, through the setting and Control (start and stop of the fan, rotation speed of the fan) to achieve the balance of the air pressure of each branch air path, and the air pressure at the two end points of each air leakage path is equal, that is, the external air leakage point keeps the differential pressure at zero, and the internal air leakage point keeps the air pressure equal . [0003] Compared with the large main fan ventilation system, th...
