The final step in surface coal extraction is reclamation of the mined site. Reclamation is required by both federal and state law and has, since the middle of the 20th century, become a standard and integral part of modern coalmining operations. The reclamation process actually begins before the first ton of coal is removed.

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.
