|Mponeng is a gold mine in South Africa's North West Province, about 65 km southwest of Johannesburg, owned by AngloGold Ashanti.|
|Every day the 4000 miners at the Mponeng Mine detonate 5,000 pounds of explosives. Every day they take away 6,400 tons of rock.|
The laws of compressive force dictate that the rock will try to close the spaces left by mining.
|It is estimated that at least 10% of the gold in South African mines is stolen. Criminal syndicates help illegal "ghost" miners sneak into the mineshaft, where they then hide out for months at a time, turning ghostly grey from the lack of sunlight.|
