Numerical analysis of the heat extraction performance of mine backfill heat exchanger based on phase change heat storage (PCHS-BFHE)

Deep mines contain a large amount of hot-rock geothermal energy, and one method to exploit it is to construct a backfill heat exchanger based on phase change heat storage (PCHS-BFHE) in the mine goaf. In this paper, the influence of the thermophysical parameters of phase change heat storage backfill...
