Black Coal - AIMR 2011 - Australian Mines Atlas

Under the Australian classification system, it is estimated that Australia has approximately 9.2 per cent of the world's economic recoverable black coal resources. In 2012, total world coal production of black and brown coal reached record levels and Australia was ranked fifth in the world behind China, the United States of America, India and Indonesia in terms of total coal production.

Peak Coal: How Much Remains Economically

2016-3-15  The “high” estimate of Steve Mohr has been reduced from his “Case 3” estimate of 670 Gtoe by 40 Gtoe because I have assumed lignite and black coal resources are lower than his high estimate. An update of David Rutledge’s estimate using the latest BP data through 2014 gives a URR of about 400 billion tonnes of oil equivalent (Gtoe) for coal.
