Coal Mining Methods Underground Mining Longwall Room and Pillar Mining Longwall mining and roomandpillar mining are the two basic methods of mining coal underground, with roomandpillar being the traditional method in the United States. Both methods are well suited to extracting the relatively flat coalbeds (or coal seams) typical of
Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
It began life as forests and vegetation. When this plantlife died, it rotted away and was buried and compacted into layers underground. These layers formed seams of coal that can run for hundreds of miles. Coal can be extracted in two ways: surface mining and deep mining. Surface mining, which includes the technique of opencast mining ...

Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 180 ft (55 m), are usually surface mined.
Strip mining is a variation of surface mining for thin but extensive mineral layers close to the surface with layers of soil or rock above them. Bulldozers scrape and remove layers of soil and vegetation. Explosives break up the rock overburden and enable access to mineral ore. Coal, iron, and tar sands are mined this way.
