The objective of this study was to develop, install, and test a small underground mobile refrigeration plant (M.R.P.) to deal with some of the real problems associated with mine cooling in an operating mine. The requirement for cooling the underground environment is discussed with particular emphasis on the need for this method of cooling, with the concomitant benefits. The research investigated current methods of cooling and reasons for previous failures in (M.R.P.). Both static and dynamic simulations were conducted to increase the confidence level under operating conditions. Implementation and testing, resulted in "lessons learnt" requiring modifications, which are documented. Actual results have been recorded. These results have proved that significant cooling via (M.R.P) is feasible. Main benefits include positional efficiency, cost per kilowatt of cooling and cooling opportunities for remote areas of a mine. Finally, a proven technology is now available for large-scale implementation into the mining industry. Now the ventilation engineer has another system of cooling, which can be utilized in the quest to create an occupational environment, which meets the physical and mental health requirements of the worker.
