Deepest Mines of the World


Mining deep underground is difficult and dangerous. The temperature increases with depth, typically around 1 to 3°C per 100m, will cause an increase of temperature the lower you get. A 4,000m deep mine has a temperature of between 60°C and 140°C, depending on the location. The air temperature might be controlled by pumbing cold air into the mine, but still the climate is not sutable for hard work. As a result there are very few really deep mines and they are located at consolidated areas like South Africa, where the geothermal gradient is rather low.
