Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities.

Over 7269 million tonnes (Mt) of hard coal are currently produced worldwide and 787 Mt of lignite. Coal is mined by two methods: surface or 'opencast' mining, and underground mining.
Surface mining When an ore bed has been located relatively close to Earth's surface, it can be mined by surface techniques. Surface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining.
Most modern mining techniques have high water demands for extraction, processing, and waste disposal. ... Underground Mining and Its Surface Effects.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral ...
Roman techniques were not limited to surface mining. They followed the ore veins underground once opencast mining was no longer feasible.

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 Kentucky, West Virginia, Virginia ...
Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.
Surface mining involves the extraction of mineral commodity on the earth's surface and in the open air. Surface mines can be fully mechanized, partly mechanized, or labour intensive.

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.
