Open pit mining Rutgers University

Optimum pit design plays a major role in all stages of the life of an open pit: at the feasibility study stage when there is a need to produce a wholeoflife pit design; at the operating phase when pits need to be developed to respond to changes in metal prices, costs, ore reserves, and wall slopes; and towards the end of a mine's life where the ...

Physical Aspects of Waste Storage From a Hypothetical .

Copper porphyry deposits are most often mined as open pit operations. The deposits' relatively low ore grade and hightonnage production generate significant amounts of solid waste compared with the units of copper recovered. Approximately 98 percent of the material extracted from the mine reports to .

Mining |

Surface mining. Openpit mining often (but not always) results in a large hole, or pit, being formed in the process of extracting a mineral. It can also result in a portion of a hilltop being removed. In strip mining a long, narrow strip of mineral is uncovered by a dragline, large shovel, or similar type of excavator.

LARGE SCALE SLOPE STABILITY IN OPEN PIT MINING A .

Design of open pit slope angles is becoming more and more important as the mining depths of open pits continuously increase. Small changes in the overall pit slope angle have large consequences on the overall economy of the mining operation. A case in particular is the Aitik open pit mine in northern Sweden, which currently faces the design of the overall slope angles for continued mining toward a .

Pit Optimization. A method of precise pit optimization commonly used in the mining industry is the Lerch Grossmann method. The technique, founded in 3dimensional graph theory, relies on a regular system of blocks which defines the value (profit, loss) and type (ore, waste) of material contained in the blocks.
