Coal mining - Wikipedia

Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally coal seam thickness and geology are factors in selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines requir…

Potash mining can also result in voids of similar scale to coal mining, i.e. tens of metres wide and hundreds of metres long (Chrzanowski et al., 1997). The UCG and potash examples demonstrate that even if conventional mining declines in the future, the is continued need to better characterise and de-risk estimation of surface subsidence.

Coal seams as much as five metres thick can be mined in a single “lift” by the longwall method, and seams up to seven metres thick have been extracted by conventional mining systems in one pass. However, when a seam exceeds these thicknesses, its extraction usually involves dividing the seam into a number of slices and mining each slice with longwall, continuous, or conventional mining ...
