UNCONVENTIONAL SYSTEMS FOR REMOVING HEAT FROM DEEP MINES.

Author(s) : SHEER T. J., CASTILLO D. del, CSATARY C. J.

Summary

THE COSTS OF COOLING DEEP GOLD MINES TO ACCEPTABLE TEMPERATURE LEVELS ARE INCREASING RAPIDLYAS MAXIMUM WORKING DEPTHS APPROACH 4,000 METRES. VARIOUS PROMISING CONCEPTS ARE DESCRIBED, INCLUDING THE LARGE SCALE USE OF ICE FOR MINE COOLING, AND THE INCLUSION OF A REVERSED BRAYTON AIR REFRIGERATION CYCLE WITHIN THE MINE VENTILATIONAIR CIRCUIT. THE CONVEYING OF ICE, RATHER THAN CHILLED WATER, IS ATTRACTIVE BECAUSE OF THE RESULTING SAVINGS IN PUMPING WATER OUT OF THE MINE. IN AN AIR REFRIGERATION CYCLE PART OF THE VENTILATION AIR WOULD BE COMPRESSED ON SURFACE, SENTUNDERGROUND IN PRESSURE PIPES, AND EXPANDED UNDERGROUND TO A LOW TEMPERATURE THROUGH A SUITABLE TURBOMACHINE. A POSSIBLE SYSTEM DESIGN IS DESCRIBED.
