Background review - Subsidence from coal mining activities

Background review: subsidence from coal mining activities Major underground coal mining in Australia mainly occurs in the coal basins of New South Wales and Queensland. Longwall is currently the most common method of underground coal mining in Australia, as it is safer and more efficient in extracting coal than other extraction techniques.
