||Review of the main ventilation and air-conditioning techniques used in South African mines: ventilation networks, underground cooling units, underground cooling towers, practical aspects of air cooling methods and installations, location of cooling units. Description of the most important new developments: cooling units for air pre-cooling installed on the surface close to the entry shaft; underground water spray chambers and high-output coolers for main and partial ventilation air; cooling of water used at mine faces; use of Pelton-wheel turbines for energy recovery from the pressure drop in cold water circuits. Pelton-wheel turbines may also be of use in coalmines.
