[0021] The mine return air exchanges heat with the refrigerant in the air return heat exchanger (evaporator) so that the refrigerant in the air return heat exchanger absorbs heat from the mine return air and vaporizes into high-temperature and low-pressure gaseous refrigerant. The high-temperature and low-pressure gaseous refrigerant is compressed into high-temperature and high-pressure gaseous refrigerant in the compressor of the air-cooled heat pump 11, and the high-temperature and high-pressure gaseous refrigerant is condensed in the first circulating water heat exchanger (condenser) to release heat. The first water circuit cooperates with the first circulating water heat exchanger so that the cold water in the first water circuit absorbs the heat of the first circulating water heat exchanger to obtain hot water, which is discharged from the first water outlet 111 of the first water circuit of the air-cooled heat pump 11.

[0022] Thus, the air-cooled heat pump 1 can absorb heat from the mine return air and produce hot water.

The first hot side has a mine water inflow 211, and the first cold side has a first heat exchange water inlet and a first heat exchange water outlet 212, which is matched with the mine water heat exchanger to exchange heat.

[0033] Thus, the heat exchange water can exchange heat with the mine water in the first heat exchanger 21 to heat the heat exchange water by the mine water. Subsequently, the heat exchange water after absorbing heat flows into the first water source heat pump 12 and exchanges heat with the refrigerant in the mine water heat exchanger to absorb heat in the heat exchange water by the refrigerant. As described above, the refrigerant releases heat in the second circulating water heat exchanger of the first water source heat pump 12 to heat the cold water in the second water circuit. By arranging the first heat exchanger 21, impurities in the mine water can be prevented from blocking the first water source heat pump 12 to prolong the operation time of the first water source heat pump 12 and the metal mine waste heat coupling device 100.

[0040] As shown in Figure 1 and Figure 2 , the water inlet of the plant and auxiliary building heating device 400 is in communication with the fourth water outlet 141 of the third water source heat pump 14 (fourth heat exchanger), so that the hot water output by the third water source heat pump 14 (fourth heat exchanger) flows into the plant and auxiliary building heating device 400.

Thus, when the hot water produced by the air-cooled heat pump 11 is sufficient for the wellhead heat preservation device 200 and / or the machine room auxiliary room heating device 300 to use, the excess hot water can be transported to the heat supply pipe network 500.

[0047] By adjusting the flow regulating valve on the at least one of the third branch pipe 33 and the fourth branch pipe 34, the flow of hot water flowing through the third branch pipe 33 and the fourth branch pipe 34 can be adjusted. Thus, when the hot water produced by the first water source heat pump 12 is sufficient for the wellhead heat preservation device 200 and / or the machine room auxiliary room heating device 300 to use, the excess hot water can be transported to the heat supply pipe network 500.

[0048] By adjusting the flow regulating valve on at least one of the fifth branch pipe 35 and the sixth branch pipe 36, the flow of hot water flowing through the fifth branch pipe 35 and the sixth branch pipe 36 can be adjusted.
