Abstract
A method and apparatus for cooling an aqueous liquid at ground level, by a refrigeration system which rejects heat, to produce an aqueous ice slurry of ice crystals in the aqueous liquid; and (A) feeding some of the aqueous ice slurry from ground level to a heat exchanger in a mine chamber substantially below ground level to cool air or water in the mine chamber by heat exchange with the slurry thereby producing warm aqueous liquid from the slurry; withdrawing the warm aqueous liquid from the mine chamber, returning it to ground level and then cooling the aqueous liquid by the refrigeration system to again convert it to an aqueous ice slurry; and recycling the slurry to the mine chamber; and (B) feeding some of the aqueous ice slurry produced at ground level to an ice washer and washing the ice; melting the washed ice to produce potable water at ground level; and feeding the potable water to hydraulic powered machinery in the mine chamber and using the hydrostatic energy of the water to power the machinery.
