When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This ...

Opencast mining is also known as openput mining, opencut mining, surface mining and also as strip mining, the later term being commonly used in the for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

mining: Openpit mining Deposits mined by openpit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it.

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.

Nov 05, 2015· About the Author. Keith Haddock has had a long career in earthmoving and surface mining. After graduating as a professional engineer, he worked for major earthmoving contractors in the UK on highways, dams and opencast coal sites until moving to Canada in 1974 to work for a large surface coal mining company.

Opencast coal mining: process and method Opencast mining, a method of mining introduced in 1942 to maintain coal supplies du ring the Second World War, is a quarrying method that is viable where a coal seam is relatively near the land surface or where a pit can expose a number of seams within an acceptable depth (normally up to 100m in the UK).

CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act of 1976 charged OTA to assess the feasibility of the use of deepmining technology on leased areas. With the passage of the Surface Mining Control and Reclamation Act of 1977 congressional interest in the study of deep underground mining technology shifted

Opencast Mining. Opencast mining is the most common method used throughout the world for extracting minerals (Ha et al., 2011) and commonly produces much waste, due to the removal of large volumes of materials (Anawar et al., 2013; Bini, 2012).

The planning of an open pit mine is, therefore, basically an exercise in economics, constrained by certain geologic and mining engineering aspects. A bench may be defined as a ledge that forms a single level of operation above which mineral or waste materials are mined back to a bench face.

Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.
