Answer:
Mponeng gold mine in South Africa..
Explanation:
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.
The temperature of the rock reaches 66 °C (151 °F), and the mine pumps slurry ice underground to cool the tunnel air to below 30 °C (86 °F).
A mixture of concrete, water, and rock is packed into excavated areas, which further acts as an insulator.
Tunnel walls are secured by flexible shotcrete reinforced with steel fibers, which is further held in place by diamond-mesh netting.
Hope it helps you..
