Author(s) : RAMSDEN R.

Type of article: Article

Summary

WITH MINES PRESENTLY AT 3,600 M BELOW THE EARTH'SSURFACE WHERE THE VIRGIN ROCK TEMPERATURE IS AT ABOUT 333 K (60 DEG C), IT IS DIFFICULT TO MAINTAIN A WET BULB TEMPERATURE OF 300 K (27 DEG C) WHICH IS ESSENTIAL TO PROVIDE AN ACCEPTABLE THERMAL ENVIRONMENT. ANOTHER PROBLEM IS THE LOCATION OF THE REFRIGERATING INSTALLATION: A SURFACE INSTALLATION OR AN UNDERGROUND SITE. THE PROS AND CONS OF THESE OPTIONS ARE DISCUSSED AND ANALYSED IN RELATION TO CURRENT MINE COOLING PRACTICES. WITH CONSIDERATION ALREADY BEING GIVEN TO EXTENDING MINING ACTIVITIES TO DEPTHS OF 4,000 M AND MORE, THERE WILL BE ADDED PROBLEMS IN SOLVING THE AIR CONDITIONING REQUIREMENTS FOR DEEP MINES. A. H.
