南非矿山的特点是开采深度大和岩石温度高。最深的采场距地表约3600米,原岩温度约60℃。目前正在进行开采深度距地表4000米的设计工作,岩石温度将达70℃以上。目前,采用通风和致冷相结合的方法控制热环境。南非金矿的总通风量约3500米~3 South African mines are characterized by large mining depths and high rock temperatures. The deepest stope is about 3600 meters above the earth’s surface and the original rock temperature is about 60 ° C. Mining is currently under way to 4000 meters from the surface of the design work, the rock temperature will reach 70 ℃ above. At present, the combination of ventilation and cooling control the thermal environment. South Africa’s gold mine’s total ventilation of about 3,500 meters ~ 3
