[0042] figure 1 A schematic diagram of the overall structure of a thermal system for deep mining is shown. Such asfigure 1 As shown, the thermal system of deep well mining includes three parts, which are the return air shaft part, the underground chamber part and the working face (mining area) part, in which the return air shaft part is equipped with a cooling tower 8, and the underground chamber part is equipped with an evaporator 2 , an expansion valve 3, a compressor 1 and a condenser 4, and the air cooler 6 is arranged on the working surface. The air cooler 6 is used to cool downhole air, and the evaporator 2, expansion valve 3, compressor 1, and condenser 4 constitute a refrigeration system; the cooling tower 8 and the condenser 4 constitute a circulation pipeline, and the air return shaft After the air in the cooling tower 8 exchanges heat with water, the water enters the condenser 4 through the pipeline, and exchanges heat with the refrigerant in the condenser 4.
