Open-pit mining. Some 53% of South Africa’s coal is produced from surface mining, via open-cast or open-pit mines. This is because the coal is less than 60 metres below the surface. Open-pit mines use draglines, as well as truck and shovel operations to extract coal. A dragline excavator uses a dragline to pull a bucket by a wire cable.
The world’s deepest mine is the Mponeng gold mine in South Africa, which extends to a depth of almost 2 miles below the Earth’s surface. Mining is a process of extracting minerals and metals from the Earth. These materials occur in their impure form, called ‘ores’, which are concentrated in certain regions in the form of ‘deposits’.
Economic activity in modern-day South Africa has been centred on mining activities, their ancillary services and supplies. The country’s stock exchange in Johannesburg was established in 1887, a decade after the first diamonds were discovered on the banks of the Orange River, and almost simultaneously with the gold rush on the world-famous Witwatersrand.
