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.
How is a coal formed?

Why does Australia rely on coal?
Coal is primarily used as a fuel to generate electricity and in Australia is used to produce about 80% of the nation’s electricity requirements. … These early coal mining activities made a significant contribution to the progress of European settlement in Australia.
How many years of coal are left?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.
