Mining optimisation
The Australian mining companies of today spend millions of dollars planning and managing
their mining operations. The viability of a mine depends on many factors, including availability,
product price and quality, as well as environmental considerations.
Through a process called linear programming, many of these factors are represented using
linear equations and straight-line graphs. From these equations and graphs an optimal
solution can be found, which tells the company the most efficient and cost-effective way to
manage all of the given factors. Such use of simple linear graphs can save companies many
millions of dollars.
