This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining). Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery.

Surface mining of coal is an alternative to underground mining, and it is practiced as strip mining, the most common form, and auger mining. Some coal is also produced through dredging and culm bank (i.e., anthracite waste piles) recovery, but these quantities tend to be relatively small compared to underground, strip, and auger mining.
