Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...
"Many mines start out as open-pit operations and move on to underground mining at a later stage, depending on the location and grade of the ore deposit," says Lauri Laihanen, Vice President, R&D and Product Management, Surface Drilling Division at in Finland. "It's more expensive to extract material underground, so it has to ...

Aerial imaging of an open-pit mine integrated with the visual analytics offers a novel approach for routine monitoring of tension cracks for mine safety. Tension cracks may occur on work- or catch-benches that are excavated according to a computer aided design (CAD) model. The size of the tension cracks, their locations, and evolutions is …
In large-scale open pit mines, the mining process is rather complex and often involves different run-of-mine (ROM) ore and waste material treatment downstream. Appropriate areas to place these large amounts of material are limited and their selection and design must serve the environmental factors and economic goals of the long-term …
Kalgold is a long-life, open-pit gold mine on the Kraaipan Greenstone Belt, 55km southwest of Mahikeng in North West province. Mining takes place from the A-zone pit, where activities are ramping up at the pillar between the pit and the Watertank pit. Mined ore is processed at the carbon-in-leach Kalgold plant.

Open pit mines allow for heavy machinery and workers to do their jobs in the open and usually with more maneuverability. Open pit mines don't have to safeguard against loss of air and cave-ins, but they do have their own set of strict safety guidelines that save lives. While there isn't as much of a danger of cave-ins, rock slides and other ...
Mining activities, and especially open-pit mines, have a significant impact on the Earth's surface. They influence vegetation cover, soil properties, and hydrological conditions, both during mining and for many years after the mines have been deactivated. Exploring a fast, accurate, and low-cost method to monitor changes, through years, in …
