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 …

Production planning and scheduling optimisation for underground mining operations has
continued to attract significant attention over the last decades. This has been necessitated …

Mining investment has been recognized as capital intensive due mainly to the cost of large
equipment. Equipment capital costs for a given operation are usually within the order of …

Operations research is becoming increasingly prevalent in the natural resource sector,
specifically in agriculture, fisheries, forestry and mining. While there are similar research …

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 …

Motivated by an underground mining operation at Kiruna, Sweden, we formulate a mixed
integer program to schedule iron ore production over multiple time periods. Our optimization …

The mining industry continues to face the problem of depleting grades and the subsequent
significant variation in economic, environmental and technological characteristics have been …

We present a mixed-integer program to schedule long-and short-term production at LKAB's
Kiruna mine, an underground sublevel caving mine located in northern Sweden. The model …

Stope layout designing and production scheduling are main phases to determine the
profitability of an underground mining project. These are mainly related to the output of one …

Mixed integer programming (MIP) has been used for optimizing production schedules of
mines since the 1960s. The major problem in the long-term production scheduling for an …
