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.
