The latter three ranks are commonly referred to as "black coal" while lignite is commonly called "brown coal". Coal is Australia's largest energy resource. At the end of 2019, Australia's recoverable Economic Demonstrated Resources were 75,428 million tonnes (Mt) of black coal and 73,865 Mt of brown coal.

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

Much of the technology uses standard welldrilling and production techniques. The primary difference is the total usage of water in the process. In most cases, water must be pumped out of the formation in order to allow the methane that is adsorbed onto the coal particles to escape and travel to the surface via extraction wells.
