Background
The mine air is a general term for various gas, steam and mine dust mixtures in the mine. The temperature and humidity of the air in the mine are determined primarily by the physicochemical properties of the minerals and rock formations, the depth of mining, the production process, geographical and geological factors.
At present, related equipment is arranged underground in a mine to maintain the environment, the maintenance contents comprise deep well refrigeration and cooling in summer, shaft heat preservation and freeze prevention in winter and cold and heat source design, and when heat is supplied in winter, underground gushing water is firstly utilized to extract a part of heat. Because the temperature of the mine water is high, the mine water is not suitable for directly entering an evaporator of a heat pump unit, a water mixing tank is required to be arranged, the high-temperature mine water and the water after heat extraction are mixed, and the temperature is controlled in a high-efficiency region where the heat pump unit operates. The water mixing pool can continuously supply new water and discharge water at the same time, and the temperature of the mine water is kept stable at about 30 ℃.
