Today’s fact of the world is about the deepest mine, pause for dramatic effect, in the world.
The deepest mine, in the world, is a gold mine in South Africa’s North West Province. It is called Mponeng.
It reaches/extends roughly 2.4 miles or 4 kilometres below the surface and rather unsurprisingly the trip from the surface to the bottom of the mine takes a bloody long time, over an hour.
They excavate over 5400 metric tonnes of rock a day or 5,400,000 kilograms if you prefer. That is something like 1800 African elephants. A day.
The temperature of the rock reaches 66 °C or 151 °F so they pump slurry ice into the mine to cool the tunnel air.
I’m really really glad that I don’t have to work in this mine.
