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…

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.

Coal is mined by two methods: s urface or ‘opencast’ mining or underground or ‘deep’ mining. The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.

In order to protect the miners and equipment in an underground coal mine, much attention is paid to maintaining and supporting a safe roof or overhead ceiling for the extraction openings.
