AngloGold Ashanti’s Mponeng gold mine, located south-west of Johannesburg in South Africa, is currently the deepest mine in the world. The operating depth at Mponeng mine ranged from between 3.16km to 3.84km below the surface by the end of 2018.
How hot is it in the deepest gold mine in the world?
Mponeng currently holds records as the world’s deepest gold mine and the world’s deepest mine, with depths reaching over 4.0 km below the surface. Because temperatures can reach up to 150°F in the mine at such depths, an ice slurry must be pumped into Mponeng to maintain temperatures that can be withstood by humans.

Why are deep mines hot?
Deep underground mines are “hot” work sites because of the heat from the rock itself. Ground water flowing through hot rock formations becomes hot and adds to the air temperature. Activities like drilling, blasting, and welding add to the heat load put on miners, on the surface and underground.
What is the biggest mine in the world?

What happens if you dig too deep in the earth?
To make things more difficult, as they drill deeper into the Earth, they’ll encounter extreme temperatures, possibly in excess of 1,000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure — as much as 4 million pounds per square foot in the vicinity of the mantle.
How hot is it 1 mile underground?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
Why can’t we drill to the center of the Earth?
It’s the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet’s volume. At the inner core, you’d have to drill through solid iron. This would be especially difficult because there’s near-zero gravity at the core.
