Abstract

The invention discloses an overflow type intelligent air distribution control system, which is used for intelligently managing ventilation of an underground mine. A bifurcate door and a motor for controlling the opening and closing of the bifurcate door are arranged at an air inlet cylinder in a ventilating system; at least one gas sensor and at least one differential pressure sensor are arranged in a tunnel; and a computer control system is respectively in circuit connection with the motor, a gas sensor and a differential pressure sensor and controls the motor to adjust the opening and closing sizes of the bifurcate door according to data received from the gas sensor and the differential pressure sensor, so that the air inlet quantity is controlled, and the accumulated gas can be slowly and safety exhausted. By the overflow type intelligent air distribution control system, the air inlet quantity of the air cylinder is accurately controlled in real time according to the on-site gas concentration, and intelligent control is guaranteed, so that the gas is safely and reliably exhausted, and the safety of a mine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal mine ventilation control, and relates to a device for intelligently controlling the air intake of the ventilation system according to the gas concentration in the tunnel in the coal mine ventilation system. technical background [0002] The underground shaft ventilation system is an important part of the underground mine, which is of great significance to the safe production of coal mines. For a long time, most coal mines in my country have insufficient safety investment, aging safety facilities, and defects in ventilation management. Especially when the fan fails and shuts down, the air supply stops, the gas accumulates in the roadway, and the gas concentration in some areas is too high, which seriously threatens mine safety. [0003] The mine ventilation method in our country is mainly to use the main ventilator of the mine to ventilate the underground, and the main ventilator is installed on the ...
