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 …

Determining the mining sequence is one of the main objectives in mine planning. However,
depending on the size of the analyzed instances, such activity might become an extremely …

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

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

Underground mine production scheduling possesses mathematical structure similar to and
yields many of the same challenges as general scheduling problems. That is, binary …

Scheduling activities in an underground mine is a very complex task. Precedence relations,
the great number of resources and the large number of work sites are some of the reasons …

Underground mine schedules seek to determine start dates for activities related to the
extraction of ore, often with an objective of maximizing net present value; constraints enforce …

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 …

Effective computational methods are important for practitioners and researchers working in
strategic underground mine planning. We consider a class of problems that can be modeled …

There are multiple stages in a mining operation in which a mining engineer must draw
polygons to be used as operation guidelines. These polygons are drawn by hand and based …
