A mine cooling and dehumidifying system includes a compressor, a gas-liquid separator, an evaporator, a condenser and an expansion valve. The evaporator is in an air supply well, and the condenser is in a return air well; the compressor, the gas-liquid separator and the expansion valve are all between the air supply well and the return air well; an inlet of the compressor is connected to a refrigerant outlet of the evaporator through the gas-liquid separator, and a refrigerant inlet of the evaporator is connected with an outlet of the expansion valve; an inlet of the expansion valve is connected with a refrigerant outlet of the condenser, and a refrigerant inlet of the condenser is connected with an outlet of the compressor. In the present disclosure, by vapor compression type refrigeration cycle, the downhole air heat is transferred to the return air and then discharged to the ground.
