Relatively shallow coal deposits are generally extracted by surface mining, and deeper deposits are extracted by underground mining (more detailed descriptions of surface and underground mining processes can be found in Appendix E). There are also situations in which a seam is mined by surface methods first, and then if adequate reserves are still available, the mine is developed for underground extraction. Where remaining reserves are limited, other methods of mining—such as auger mining

COAL EXTRACTION AND PROCESSING WordPress

Subsurface coal mining is the second major stage in the process of coal extraction and processing wherein coal is removed from underneath the surface of the earth. During the mining stage, workers use powerful machines to drill into the earth and extract raw coal which can be refined during the processing stage.
