In Australia, nearly 80% of coal is produced from open-cut mines in contrast with the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is cheaper than underground mining and enables up to 90% recovery of the in situ resource. Coal may be used without any processing other than crushing and ...

Removing the rocks on top of the coal, called "surface mining" or "strip mining", requires putting those rocks on top of something else, breaking the coal loose with machines or explosives, hauling the coal away to be burned, and then either putting the rocks back on top or just ...
