This review examines the current state-of-the-art in short-term planning for open-pit mines,
with a granularity that spans days, weeks or months, and a horizon of less than one to two …

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 …

Even with state-of-the-art hardware and software, mixed integer programs can require hours,
or even days, of run time and are not guaranteed to yield an optimal (or near-optimal, or …

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 …

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

The open pit mine production scheduling problem determines a sequence of three-
dimensional, notional block extraction that maximises net present value (NPV) of future cash …

This paper presents the development and implementation of an innovative mixed integer
programming based mathematical model for an open pit mining operation with Grade …

At the time of this writing, the US Geological Survey estimates that the average American-
born human will need millions of pounds of fuels, minerals, and other extracted resources in …

A recursive time aggregation-disaggregation (RAD) heuristic is proposed to solve large-
scale multidimensional and multiperiod precedence-constrained knapsack problems …
