Open-cast Mining
For bedded deposits like coal seams, open-cast proves to be the most efficient method for near-surface ore. Casting overburden on mined-out areas means that material handling during mining is just excavation and casting, which can be done by a single machine. This also enables mining to be concentrated in small areas, and …

Depending on your needs we can supply cast iron or all metal motors with various efficiencies to suit your capex and opex requirements. In some applications, like deep pit open cast mining, it makes sense to supply pumps complete with diesel driven skid or trailor mounted units for easy positioning where the water is settling.
7.3.4: Highwall Mining | GEOG 000
7.3.4: Highwall Mining. Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more sophisticated machine, known as a highwall miner. The highwall miner shares some common elements with a continuous mining machine.

Surface Mining Techniques used in the Oil Sands
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
