Title Ventilation techniques developed in South Africa.

Abstract A review of recent developments in mine ventilation techniques in deep gold mines and other minefields in South Africa, with emphasis on general air conditioning in mining (comparison of virgin rock temperatures at various depths, between German, United Kingdom, USA and South African mines, shown graphically); core body temperatures (CBT), wet bulb temperatures (WBT), thermal comfort aspects for creating a more favourable microclimate for mineworkers (WBT above 27.5░C considered hot; CBT of 37░ desirable, mine air velocities considered best under 2m/s). Other aspects considered: heat given off by machinery underground; tolerable WBT limits by cooling and ventilation; avoidance of supplementary underground fans; cooling tower; chilled water borne in insulated pipes for deep underground dust wetting; cost aspects. Diagram of a typical underground refrigerated cooling system for deep mines.
