| Abstract | Heat can be stored in ground waters, which fill up old mining workspaces, and in aquifers of slow migrating waters. The most effective, however, would be use of especially constructed tank reservoirs inside existing mining openings either underground or in open pits. The delivery of heat to the store can be done with use of heat exchangers or by direct injection of hot water. Recovery of stored heat will be possible through heat exchangers operating in a reverse-circulation mode or, by direct pumping out of hot water from the store space. |
