Abstract

The invention provides a coal mine ventilation system and a control method thereof, and relates to the technical field of mine ventilation. The ventilation system includes: a main fan device for purifying the air and transporting the purified air into the mine, and at the same time for gas recovery processing; a storage device for storing liquefied carbon dioxide and converting it into carbon dioxide gas for fire fighting; auxiliary The fan device is used to transport purified air into each branch mine and detect the wind speed and air volume of ventilation in the mine; the detection terminal is used to detect the temperature, fire and gas concentration in each branch mine. Air purification, dust reduction and cooling can be achieved through air purification devices, negative ion generators and atomizers, and individual environmental detection of each mine can be achieved through wind speed sensors, air volume sensors, temperature sensors, and gas concentration sensors. And carbon dioxide liquefaction storage tanks can achieve fire extinguishing, and gas recovery can be achieved through gas recovery devices.

Description

technical field [0001] The invention relates to the technical field of mine ventilation, in particular to a coal mine ventilation system and a control method thereof. Background technique [0002] The ventilation system of the mine occupies a very important position. An excellent ventilation system not only discharges the exhaust gas and dust generated in the production process out of the well and keeps the air fresh at the working point, but also must remove the gas and dust generated in the mine. Combustible gases such as biogas are dispersed and kept within a safe concentration range. It can be seen that an excellent ventilation system is very important to ensure the safe production of coal mines. An excellent ventilation system can not only ensure production safety, but also has Real-time controllable air volume, good operability, economical operation and other characteristics. [0003] However, the common coal mine ventilation system has a single function and can only ...
