Continuous mining and transport of medium-hard

The majority of hard rock opencast mines are still using haul trucks as their main materials transport system. However, an increasing number of mine operators have substituted their systems for hauling the mineral and/or waste materials with belt conveyors or are at least planning to do so. These in most cases quite capital-intensive projects require a careful selection and rating of the ...

Opencast Mining - an overview ScienceDirect Topics

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 ( Figure 11 ).

Coal mining - Wikipedia

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 equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors. In this mining method, explosives are ...

Geotechnical Aspects of Overburden Materials for

The choice of mining method is largely determined by the geology of the coal deposit. Opencast mining is a mining process that generates huge amount of rock waste. Waste rock material generated along with mining is called mine overburden (Prashant et al., 2010). During opencast mining, the overlying soil is removed and the fragmented rock is heaped in the form of overburden dumps (Ghosh, 2002 ...
