[0002] As new energy sources continue to develop, the proportion of coal in energy consumption is gradually decreasing, and the number of abandoned mines is relatively increasing. Multi-source coupled abandoned mine geothermal and pumped storage devices, which transform abandoned mines, are also gradually developing. These devices first use other new energy sources, such as solar and wind power, to lift water from the mine reservoir below and pump it into the mine reservoir above for storage. When power generation is needed, the water in the mine reservoir above is used to generate electricity using the height difference.
