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 ...

Coal | Geoscience Australia

2021-9-14 · 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

Physics of Coal and Mining Processes - 1st Edition ...

2017-3-30 · Around the world, on average, four coal miners die for each million tons of coal recovered. Improving the safety of mining work while responding to the need for increased coal production, however, is impossible without further development of the physics of mining processes. A relatively new branch of science, it tackles problems that arise during mineral products recovery, particularly safety ...
