CONFIGURATION AND CONTROL OF MINE REFRIGERATION AND CHILLED WATER DISTRIBUTION SYSTEM.

Author(s) : BAUER Z. J.

Summary

THE PAPER DESCRIBES THESE PROBLEMS RELATED TO A SOUTH AFRICAN GOLD MINE WHERE THE WORKING FACES MAY BE 3,300 METRES BELOW GROUND AND A SIMILAR DISTANCE FROM A SHAFT. SURFACE SYSTEMS OPERATE WITH NORMAL PROBLEMS, BUT UNDERGROUND, SPRAY COOLERS ARE USED TO PRODUCE VIRTUALLY SATURATED AIR AT ABOUT 295 K (22 DEG C) AND CONDENSERS USE WATER UP TO 313 K (40 DEG C) WHICH IS PRODUCED FROM COOLING TOWERS IN HIGH AMBIENT AREAS. WHEN OPEN SYSTEMS SUCH AS THESE ARE USED, THE SOLIDSPICKED UP BY THE WATER MUST BE REMOVED IN SETTLING TANKS, CORROSION MUST BE COUNTERED AND HARDNESS EFFECTS ARE INTENSIFIED. METHODS OF DEALING WITH THESE PROBLEMS ARE DESCRIBED. D.W.H.
