Abstract

Using various air cooling systems in underground mines results from harsh climatic conditions at workplaces. Underground refrigeration plants with compressor chillers are widely used in air cooling systems. The efficient operation of refrigeration units depends on the proper condensation heat rejection. Cooling capacity and localization of a refrigeration plant have the most significant influence on deciding of rejecting condensation heat to air or water. The limitation of the heat rejection capacity of return air streams in a typical mine and conditions facilitative to using underground water from an underground mine dewatering system is presented. Determinants and opportunities for heat recovery from water discharged to the surface are also discussed.
