The Mining Process Introduction underground COAL

The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from surface section for these terms). Once access has been ...

Coal Geoscience Australia

In Australia, nearly 80% of coal is produced from open-cut mines in contrast with the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is cheaper than underground mining and enables up to 90% recovery of the in situ resource. Coal may be used without any processing other than crushing and ...

Black Coal Geoscience Australia

03/04/2016  Over time, coal progresses in rank from lignite, to sub-bituminous coal, to bituminous coal and finally to anthracite; a process known as coalification. As the coal increases in rank, the carbon content - and hence the energy content - increases, whilst the moisture content decreases. In Australia, sub-bituminous, bituminous and anthracite are collectively referred to as black coal, whilst ...

Coal Geology Geoscience Australia

Many underground coal mines in Australia use longwall mining methods, which enable extraction of most of the coal from a seam using mechanical shearers. The mining ‘face’ can be up to 250m long. Self-advancing, hydraulic powered supports temporarily hold up the roof while the coal is extracted. The roof over the area behind the face, from which the coal has been removed, is then allowed to ...
