Slope Design and Implementation in Open Pit Mines

Jan 01,  · Principles of slope design in open pit mines Considering the importance of stakes, the slope design in open pit mines must be based on a well-controlled methodology, especially since experience shows that each rock mass characterized by its geological structure is unique, and therefore there are no standard recipes that achieve the right solution with certitude.

Pit Optimization – How I View It

Jun 03, · One of the first steps in open pit mine design is the pit optimization analysis. Pit optimization is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters include the metal prices, process recoveries, and operating costs. Normally when optimization is done, a range of metal prices or revenue factors is used to develop a series of nested shells to understand how the mine will expand or shrink with increas

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

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

Surface mining planning and design of open pit mining

Jan 09, · Scrapers are sometimes used in special situations. Large bucket-wheel excavators of the kind used in European coal mines have not been applied to metal mining, because this equipment is best adapted to softer bedded, relatively flat-lying strata. Many factors govern the size and shape of an open pit. These must be properly understood and used in the planning of any open pit operation. The following are the key items affecting the pit design: 1) Topography, 2) Geology, 3) Grade, 4
