Applications of operations research to mine planning date back to the 1960s. Since that
time, optimization and simulation, in particular, have been applied to both surface and …

The problem of long-term production planning of open pit mines is a large combinatorial
problem. Application of mathematical programming approaches suffer from reduced …

Given a discretisation of an orebody as a block model, the open pit mining production
scheduling problem (OPMPSP) consists of finding the sequence in which the blocks should …

We present a methodology for long-term mine planning based on a general capacitated
multicommodity network flow formulation. It considers underground and open-pit ore …

Real-time monitoring makes it possible to detect any disturbance occurring in production,
while decision instruments can efficiently assist decision-makers to optimize production …

An open-pit mine schedule defines the optimal sequence of mining valuable (ore) and waste
material with the objective of maximizing the value of the project. Given this production …

Three-dimensional block models are the most frequently used tool for estimating mineral
resources and reserves within a mineral deposit. In open pit mining, the basis of mine …

Two aspects of open-pit optimization that are often neglected are production scheduling and
the incor-poration of haul roads and safety berms in the design. The production scheduling …

One of the most important design factors in open-pit mining is determination of the optimal
pit. Pits may be redesigned many times during the life of a mine in response to changes in …

Ultimate limits of an open pit, which define its size and shape at the end of the mine's life, is
the pit with the highest profit value. A number of algorithms such as floating or moving cone …
