Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.

The main mineral extracted by this method is coal. Coal is mined by removing the land above the seams. This method of coal mining is mainly conducted on the Appalachia Mountain in the United States. The coal cannot be mined using simple machines. Explosives are used to mine the coal and the excess coals are dumped in the nearby valley.

Coal resources and the operator resources contribute equally to the completion of this process. The most important equipments which are required for this method of mining are backhoes, shovels, and bulldozers which are all earth moving equipments. These equipments are generally used for many construction activities.

Strip Mining. Strip mining gets its name from the fact that the process involves stripping the surface away from the mineral that's being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. This type of mining makes sense when the mineral is near the surface.
