Can underground pumped storage power stations convert coal mines into decentralized power supply systems?

Underground Pumped Storage Power Stations (UPSPS) has the potential to convert underground coal mines into vital components of decentralized power supply systems.

Are underground pumped storage power stations a viable post mining land use?

Underground pumped storage power stations (UPSPS) is a form of beneficial post mining land use for closed underground coal mines. Its development potential is still largely unexplored in China. In this paper, a two-phase evaluation framework is developed for the site selection of UPSPS from regional to local scale. The main findings are as follows:

How can a pumped storage power station be used in abandoned mines?

Form a pumped storage power station as the core, and build an integrated base for diesel power generation, gas power generation, and photovoltaic power generation in abandoned mines to provide power protection for production and life ( Figure 7 ). Figure 7. Integrated development. 5.2.2. Full Development of Regions Adjacent to Abandoned Mine Shafts

Which upper reservoir should be selected for a coal mine?

In cases where there is more than one suitable upper reservoir for a given coal mine, the one with the storage volume closest to that of the coal mine is selected (10 %). For an upper reservoir with several coal mines, the mine with the closest storage volume (10 %) should also be selected.

Can a pumped storage hydropower plant convert intermittent electricity into useful energy?

Pumped storage hydropower (PSH) plants built in abandoned mine shafts can convert intermittent electricity into useful energy. However, studies on basic theories and key technologies are a pressing issue.

What is the distance between coal mines and water reservoirs?

The horizontal distance (D) between coal mines and corresponding nearby existing water reservoirs averages at 13.29 km, with a median of 14.01 km (Fig. 12 (a)). Subsequently, based on the DEM data, the elevation of coal mines and water reservoirs are determined.
