An Open Pit Design Model - SAIMM

pit volume and shape, mine life and plant capacities are interdependent with each other, the other unknowns and the given data. Traditional pit design In the traditional approach to pit planning (Soderberg, et ai, 1968), two broad assumptions are made to overcome the problem of too many unknowns. Firstly, the cut-off grades are

Optimum ramp design in open pit mines - ScienceDirect

The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational costs. Because in-pit ramps require the removal of a considerable amount of non-valuable material (stripping), we discuss two ...

(PDF) Guidelines and Considerations for Open Pit Designers ...

Some designers will design a 12% against road shoulder and 2H:1V on the outside, with ramp for the final couple of benches in a pit, thinking a minimum depth of 0.3 m (giving a 1.5 m width – see that it will help increase ore recovery in pit bottom, for example in Figure 6). Depth and width however are minimal inefficiency with the trucks.
