Answer 2

The depth of the deepest mine in South Africa is about 4km.

• (b) 4 km is the correct option.

• In South Africa near Johannesburg is the deepest mine in the world named AngloGold Ashanti's Mponeng gold mine.

• By 2012, the operating depth had precisely reached 3.9-km below the surface, and later extensions have arisen in digging below the 4 km mark.

• In 2012, the mine almost elicited 405,000 oz of gold. Rock walls mine touch temperatures 60°C and humidity levels exceeding 95%. For keeping things cool, more than 6,000 tonnes of ice slurry are imposed into underground reservoirs, and huge fans aid airflow. Every day, about 5,000 lb of explosives are adopted.
