As a geologist with extensive experience in underground mining environments, I can provide some insights into the temperature conditions in deep mines. The temperature in the deepest parts of a mine can be quite significant and is influenced by several factors including the geothermal gradient, the type of rock, the depth of the mine, and the presence of any hydrothermal activity.
The geothermal gradient, which is the rate at which temperature increases with depth, varies depending on the location of the mine. On average, the temperature increases by about 25 to 30 degrees Celsius (77 to 86 degrees Fahrenheit) per kilometer of depth. However, this can be higher or lower in certain regions. For instance, in areas with high geothermal activity, the increase can be much steeper.
The type of rock also plays a crucial role in determining the temperature. Different rocks have different heat capacities and thermal conductivities, which affect how they absorb and transfer heat. Rocks with high heat capacity can store more heat, while those with high thermal conductivity transfer heat more efficiently.
The depth of the mine is another critical factor. As mines go deeper, the temperature tends to increase due to the geothermal gradient. For example, the rock face temperature in the deepest mines can reach up to 60 degrees Celsius (140 degrees Fahrenheit), as you mentioned.
The presence of hydrothermal activity, such as hot springs or geysers, can also significantly affect the temperature. These phenomena occur when heated water circulates through the rock and brings heat to the surface, which can raise the temperature in the surrounding area.
It's also worth noting that the temperature in a mine can be influenced by the mining operations themselves. The process of mining can generate heat through friction and the use of heavy machinery, which can temporarily raise the temperature in the worked areas.
In the specific case of the mine you mentioned, which reached a depth of 3.9 km (2.4 mi) by 2008, becoming the deepest mine in the world, the temperature at the rock face would be expected to be quite high. Given the geothermal gradient and the depth, it's plausible that the temperature could reach or even exceed 60 degrees Celsius (140 degrees Fahrenheit) at the rock face.
However, it's important to remember that these temperatures can vary significantly and are not uniform throughout the mine. There can be pockets of cooler or warmer areas depending on the local geological conditions. Additionally, modern mining operations often implement cooling systems to manage the heat and ensure the safety and comfort of the workers.
In conclusion, the temperature in the deepest parts of a mine can be quite extreme, reaching up to 60 degrees Celsius (140 degrees Fahrenheit) or more at the rock face. This is influenced by the geothermal gradient, rock type, depth, and hydrothermal activity, among other factors. Mining operations can also generate additional heat, and cooling systems are often used to manage these conditions.

The rock face temperature reaches 60 --C (140 --F). By 2008, the mine reached 3.9 km (2.4 mi) underground. This made it the deepest mine in the world, surpassing the 3.5 km (2.2 mi) deep East Rand Mine by a considerable margin.
