Thermal energy recovery for deep mines.
Eng Min J 1982 May; 183(5):98-99
High temperatures and humidities in deep mines make a comfortable working environment difficult and expensive to maintain. Large quantities of refrigeration water must be carried down long, vertical pipelines. The electrical costs of this refrigeration are rising owing to increased demand and rising kilowatt-hour costs. Converting the energy of falling water into useful work is a well-developed engineering concept. Much of the electric power consumed in the United States is generated this way. Water that flows down long, vertical pipelines into deep mines could be used to operate a turbine at the bottom of the pipeline.
