between surface mining and subsurface mining

Surface mining - Wikipedia

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 deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

SURFACE MINING AND ITS SOCIO-ECONOMIC IMPACTS AND ...

(Wikipedia, 2008). There is therefore a continuous divergence of interest between land required for surface mining and other land uses such as farming and housing, among others. In recent years, surface mining has been promoted in many mining countries because of the following reasons:

Strip Mining, Open-pit Mining, Surface Mining, Mining ...

Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining.

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.

The Actual Difference Between Surface and Underground Mining

In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

Surface mining, which is also known as strip mining, is when soil and rock overlaying mineral deposit is removed. It can cause habitat destruction, air pollution from dust particles, soil erosion and pollution. Subsurface mining is removing deposits from the Earth by drilling underneath layers of rock and dirt.

An Introduction To Surface Mining

Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons. It is less expensive, there are fewer complications in terms of electricity and water and it is safer. However, surface mining can be environmentally more damaging than subsurface mining.
