||Review of technical data on air-conditioning networks and the problems due to depth in mines. In spite of very adequate ventilation air flows, air conditioning is essential for work in these mines. Standard techniques involve installation underground of a cooling unit close to the return air shaft. Description of performance and technical data of cooling plant (turbo-compressors with a power of 1,000-3,000kW, water and air refrigerants), pipework insulation, and costs. The total cooling power in South African gold mines is estimated at 225,000kW. Ventilation and air conditioning are coordinated to keep the wet-bulb temperature below 31°C. Description of a standard acclimatisation method for new miners (8 days in a climatic chamber with an effective temperature of 31°C); evaluation of physical working capacity of Bantu miners.
