Obtaining energy from cooling circuits in deep mining installations

摘要

It is known to use the heat contents of the mine water for energy purposes. In a further development of this idea, it is proposed according to the invention to use the heat which occurs when the air is cooled in the heat exchangers. It is expedient for this to be done such that the mine heat is cooled decentrally via heat exchangers, and the coolant is conveyed via the liquid as far as the vicinity of the shaft and is exchanged there once more in order to render the carrier medium gaseous so as then to be made available above ground through its own lift (buoyancy) for the purpose as a liquid after being re-exchanged of generating kinetic energy in order to operate a liquid turbine. A considerable saving of energy is achieved due to the fact that the heat of exchange incident in the underground cooling system is re-exchanged in an underground circuit and is brought above ground without additional outlay of energy via an evaporated carrier medium.
