Can't believe there are 12,500 mines. That's nuts.
Almost as nuts as how fast it gets hot as you dig deeper.
The rock’s ambient temp around the mine is around 151 degrees F. They have to pump down an ice slurry from the surface to regular temps.
The Kola mine stopped because the pressure, rock density, and temperature resulted in the rock acting more like a plastic making deeper drilling impossible.
