Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground. ...

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.

Mining. In Australia, nearly 80% of coal is produced from opencut mines, in contrast to the rest of the world where opencut mining only accounts for 40% of coal production. Opencut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource.
