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 …

There is an everlasting distance and interdependence between mines and end-users as it
involves different types of equipment, infrastructure, and facilities, including excavators …

Similar to the mixed-integer programming library (MIPLIB), we present a library of publicly
available test problem instances for three classical types of open pit mining problems: the …

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

We describe new algorithms for solving linear programming relaxations of very large
precedence constrained production scheduling problems. We present theory that motivates …

A hyper-heuristic refers to a search method or a learning mechanism for selecting or
generating heuristics to solve computational search problems. Operating at a level of …

Given a discretized representation of an ore body known as a block model, the open pit
mining production scheduling problem that we consider consists of defining which blocks to …

In a global environment where energy and labor are becoming increasingly expensive,
continuous mining systems such as In-Pit Crushing and Conveying (IPCC) systems have …

A large number of metal deposits are initially extracted via surface methods, but then
transition underground without necessarily ceasing to operate above ground. Currently …

Long-term open-pit mine planning is a critical stage of a mining project that seeks to
establish the best strategy for extracting mineral resources, based on the assumption of …
