Over 95% of primary gold production in South Africa comes from underground mines. The orebodies in these mines are narrow and further characterized by geological disconti-nuities, preventing the application of mechanization and automation. South Africa hosts the worlds deepest mines, which reach depths of close to 4 km. The Chamber of Mines
