Coal Mining and Production - World Bank Group

2018. 8. 5.  Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit, with the spoil being deposited behind the operation in the previously mined areas. In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques.

The coal mining life cycle - Mining for schools

2021. 6. 21.  Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In open-pit coal mining, a pit is dug in an area and this pit becomes the open-pit mine, sometimes called a quarry.Open-pit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great.

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).

Coal Mining: How Is Coal Mined? - Science ABC

2021. 1. 7.  Underground Mining. Room and pillar and longwall are two dominant methods that account for the vast majority of underground coal mining.. Room and Pillar Mining. In this mining strategy, seams of the coal are mined partially, leaving large pillars of coal intact in a bid to support the overlying layers of rock. When they are done, miners practice what is known as retreat mining.

Coal Geoscience Australia

2021. 6. 3.  Mining. 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. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource.
