Low-temperature refrigeration cooling device for mine

A low temperature refrigerating cooling device for a mine relates to a device which is used for cooling mine and creating low temperature environment, which comprises a ground part and an underground part. The ground part comprises a lithium bromide adsorption water chilling unit, an ethylene glycol refrigerating unit, a ground return water tank and a freezing water pump. The underground part comprises a high-low pressure heat exchange device, an underground chilled water pump, an underground return water tank and a mine-used high pressure combined type air cooling device, and each element is connected through pipes. The utility model adopts residual heat of a gas power station and a gangue fired power station as power, ethylene glycol solution with low temperature which is cooled with two grades is transmitted to the high pressure side of the underground high-low pressure heat exchange device, the solution is returned to the ground and cooled in cycle after being cold and heat exchange. Hot water which is from a working place enters into a low pressure inlet of the high-low pressure heat exchange device through the return water pipe, and cold-blast air with 13-18 DEG C which is generated by the high pressure combined type air cooling device cools a mine after being heat change. The utility model has low operating cost, stable cooling property and good cooling effect, and the cooling extent is 8-14 DEG C.
