Coal | Geoscience Australia

Mining. In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut 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.

Commonly used mining techniques to extract coal - ICSC

In case of strip mining, coal seams are reached by removing the surface above them. The surface, which is referred to as overburden, is removed in long strips in this coal mining technique. The overburden taken out from the first strip is deposited outside the mining place. This process is referred to as out-of-pit dumping. The void resulting ...

Coal Geology | Geoscience Australia

Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.

Coal | National Geographic Society

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.
