Steps In Coal Mining Process

Coal mining Coal preparation Britannica

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.

4 Coal Mining and Processing Coal: Research and

24-10-2020· Coal mines require substantial capital investment in both permanent structures and depreciable mining equipment, exceeding $75 per annual ton of capacity in large underground coal mines and $30 or more per annual ton for large surface coal mines. The overall coal mining process consists of several sequential stages: (1) exploration of a

The Mining Process Introduction underground COAL

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).
