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.
field and identify the user of such terms as a ''''mining person.'''' The student of mining is thus advised to become familiar with all the terms used in mining, particularly those that are peculiar to either mines or minerals. Most of the mining terminology is introduced in the sections of this book .

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).
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.

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).

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.
Mining industry response to the book continues to be incredible. Thanks in large part to the efforts by John Chadwick of the Mining Journal,, and many other members of the mining community, the Hard Rock Miner''s Handbook has been distributed to over 113 countries worldwide.

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 ...
