METHOD OF EXTRACTION The opencast coal mining technique is used in areas were the coal reserves are scattered in shallow and thin seams and cannot be extracted by deep mining methods (Beynon et al., 2000). The opencast process starts with exploration activities to identify where there are deposits of coal and what is the depth of the seams

Open-pit, open-cast 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 mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

Open-pit 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 open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
The opencast coal mining complex extends over two mines within the Witbank Coalfield, to the south of Emalahleni, Mpumalanga Province. The target pit is currently a mature opencast strip-mining operation that extracts multi-layered coal seams, exercising a throw-over method to the low-wall side to the north and advancing in a southerly direction. The area was previously mined using a
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
