The need for more efficient mine refrigeration equipment is greater than ever, as increasing numbers of U.S. mines are being operated at greater depths in order to reach minable ore deposits. The combination of high temperatures and high humidities encountered at these depths make a comfortable working environment difficult and expensive to maintain. Many ore bodies mined today could not be mined without cooling of the underground environment. Miners' safety, comfort, and productivity all suffer if air refrigeration needs are not satisfied. The water spray coolers described in this report are efficient and economical devices for dealing with the heat problem encountered in deep mines. Four limited bulk water spray coolers were designed and built. The first of these coolers, a single-stage unit, was tested in the Mount Taylor Mine near Grants, New Mexico, before it closed. The remaining three coolers, a two- stage cooler and two three-stage coolers, were installed in the Homestake Gold Mine in Lead, South Dakota. To date, all the coolers have performed well under in-mine conditions and have required only minimal maintenance. This paper details the design and performance of these coolers.
