Geotechnical Factors In Open Pit Mine Design U.S.

1.0 N. The object of this paper is to discuss those aspects of open pit mine design which are affected by geotechnical factors. The temptation exists for some practitioners of geotechnical engineering to believe that this relatively new engineering discipline is the 'be all and end all of mining., In the opinion of the authors, this is fallacious but, as our ability to put numbers to the ...

Basics of an open pit mine - Mine Engineer.Com

2013-1-6  The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine’s life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.

Selection of practical bench height in open pit mining ...

2015-9-9  In open pit mining, factors that can affect the degree of dilution can be regarded as deposit-related or mine-related. The bench height is a mine-related parameter that can be studied using a simple geometrical model of the deposit. By changing this parameter individually, while the deposit-related parameters (such as ore

Open-Pit Mining Methods

2021-1-27  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 ...

Analysis and design of open-pit slope angles at ...

In the design of an open-pit mine, special consideration must be taken to minimize the amount of waste stripping as well as to maxi­ mize the tonnage of available ore. To achieve this goal, the overall slope of the pit wall can be steepened, thus reducing the amount of waste stripping and increasing the amount of ore removed.

A new generic open pit mine planning process with

2016-12-17  Conventionally, mining industry relies on a deterministic view, where a unique mine plan is determined based on a single resource model. A major shortfall of this approach is the inability to assess the risk caused by the well-known geological uncertainty, i.e. the in situ grade and tonnage variability of the mineral deposit. Despite some recent attempts in developing stochastic mine
