Surface mining is forms of mining in which the soil and the rock layer the mineral deposit are removed. It is the other way of insubordinate mining, in which the overlying rock is left behind, and the required mineral deposits are separate through shafts or tunnels.
Coal is mined in Appalachia by both surface and underground mining techniques. Surface coal mining methods in the steep terrain of the central Appalachian coalfields include mountaintop removal, contour, area and highwall mining. Coal mining operations are found in …

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Open-pit mining, or open-cast mining, is the most common type of surface mining. Open-pit mines are holes in the ground on a giant scale, which increase in size by blasting and drilling rock apart. The mine develops into a conical shape with Benches (or steps) in cross section which spiral round from top to bottom of the mine so that trucks can ...

The Surface Mining Unit reviews applications and approves surface mining land use plans, issues surface mining permits, conducts compliance evaluations of surface mining operations, reviews and approves bonding requirements for surface mining operations and ensures reclamation of completed mining operations.
Surface mining Opencast mining, otherwise known as surface mining consist of three different techniques: strip mining, open-pit mining, and mountain top blasting. In general, the three processes include breaking up soil and rocks via explosives and then removing debris until coal seams are exposed.
Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates.
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface.
Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.
