Title Recent developments in air-conditioning in South African gold mines and their possible application in coalmining
Original title Neuentwicklungen in der Klimatechnik des südafrikanischen Goldbergbaus und ihre Anwendungsmöglichkeiten im Steinkohlenbergbau [in German]
Bibliographic information 17 Dec. 1981, Vol.117, No.24, p.1591-1599. Illus. 8 ref.
Abstract 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.
