Ventilation system for coal mine and control method thereof

Abstract

The invention provides a ventilation system for a coal mine and a control method thereof, and relates to the technical field of mine ventilation. The ventilation system comprises a main fan device, a storage device, an auxiliary fan device and a detection terminal, wherein the main fan device is used for purifying air, conveying the purified air into the mine and carrying out gas recovery treatment at the same time; the storage device is used for storing liquefied carbon dioxide and converting the liquefied carbon dioxide into carbon dioxide gas for fire extinguishing; the auxiliary fan device is used for conveying the purified air into each branch mine and detecting the air speed and the air volume of ventilation in the mine; and the detection terminal is used for detecting the temperature, the fire disaster and the gas concentration in each branch mine. According to the ventilation system for the coal mine and the control method thereof, air purification, dust falling and cooling can be realized through an air purification device, a negative ion generator and an atomizer, independent environment detection of each mine can be realized through an air speed sensor, an air volume sensor, a temperature sensor and a gas concentration sensor, fire extinguishing can be realized through a photoelectric smoke sensor and a carbon dioxide liquefaction storage tank, and gas recovery can be realized through a gas recovery device.

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 plays a very important role. An excellent ventilation system must not only discharge the waste gas and dust generated in the production process out of the well quickly, and keep the air at each working point fresh, but also must remove the gas, dust and gas produced in the mine. Combustible gases such as methane are dispersed and kept within a safe concentration range. It can be seen that an excellent ventilation system is very important to ensure safe production in coal mines, and an excellent ventilation system can not only ensure production safety, but also have Real-time controllable air volume, good operability, economical operation mode and other characteristics. [0003] However, the common coal mine ventilation system has a single functio...
