Openpit mining. Some 53% of South Africa's coal is produced from surface mining, via opencast or openpit mines. This is because the coal is less than 60 metres below the surface. Openpit 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.
