decisions concerning the selection of mining equipment for opencast coal mines in the Witbank Area of South Africa with the object to optimize initial capital outlay and to minimize operating costs. For the purpose of this study a typical geological section of the area, consisting of soft overburden or
Open-pit mining is an extremely effective surface mining technique for extracting minerals, coal and other useful materials that are covered by relatively thin overburden layers. However, it takes the right equipment to penetrate the surface rock and reach the underlying layer in a timely and efficient manner.

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
Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut.
JCI Mining was established in 2007 and was initially involved in the plant hire of earthmoving equipment. The company progressed to doing small sub-contract load and haul projects which eventually culminated in to doing full mining contracts for clients, offering the full range of Opencast Mining services.

In the opencast operation, full seam extraction was planned, which would mean adecrease inthe calorific value ofthe coal delivered to the power station (see Fig. 2).Mter discussions with Escom, it was agreed that three generating sets ofthe station would burn coalfrom the underground mine, while the last three setswould befiredwith coalfrom the ...
however, for large-scale open pit mining in particular, the truck and loader material movement practice is the preferred method of materials handling (Czaplicki, 1992 Ta et al., 2005). Throughout this paper, we consider a loader to be any type of high productivity excavating equipment, which may
Pillar mining is one of the most challenging coal extraction methods in an opencast environment. Remnant coal pillars in old workings are also susceptible to spontaneous combustion. Not only does this degrade the quality of the coal, it also creates an extremely hazardous operating environment. As a result, overheating of equipment occurs
Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ...
