open pit mine design factors

Determining the Most Effective Factors on Open Pit Mine

Determination of ultimate pit limit, and sequence of blocks extraction through the mine life is referred as mine design and planning. The aim of mine design and planning is to develop a yearly extraction plan which guides the mining operation to the highest Net Present Value (NPV). Future mines are going to be giant mines that exploit low grade

Abstract LOP

Slope design is an integral part of the engineering of an open pit, regardless of its size. Most cases the slope angles are a key component dictating the economic viability of a proposed or current mining project. This has resulted in open pit mining operating with much lower Factor of Safety tolerances that would be used in civil engineering.

Surface mining Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious

Open-Pit Mining Methods

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
