Mining solutions developer Maptek has re-launched the open-
pit scheduler which it acquired from Orelogy in 2014 as Maptek
Evolution.
Evolution contains strategic, tactical planning and optimisation
tools for preparing development plans and medium to long term
mine schedules. The software runs on a cloud-based server using
algorithms which are ideally suited to multi-objective problems such
as scheduling.
“Processing schedules within a single solution and leveraging the
cloud is 10 times faster than traditional methods,” says Maptek Mine
Scheduling Manager Steve Craig. “Many iterations are run to analyse
the most relevant solution for a particular set of data inputs and oper-
ating conditions. Planning teams can concentrate on developing the
scenarios that add value.
“Evolution employs cut-off grade optimisation which is the single
most effective task that can add value to a project,” he continues.
“This optimisation accounts for the complex geo-metallurgical envi-
ronment, balancing mining, milling and refining capacity constraints
to maximise value and does it extremely efficiently. This complicated
process is now encapsulated in a straightforward application, so engi-
neers can readily explore where value can be added to their projects.”
Evolution’s tactical approach generates a production schedule
while also optimising the haulage fleet and the shape of waste land-
forms. This results in the optimised allocation of haul routes with
calculated cycle times, productivity and fuel burns. Scheduling across
planning horizons helps operations hit blending targets and meet
customer specifications.
“Holistic scheduling ensures optimised haulage routes and grade/
tonnage consistency throughout the mine life. Mine planners and
management can feel confident that their decisions are based on
profitability right from the start of their project. Yet there’s flexibility
to adapt to fluctuating commodity prices,” Craig added.
“Engineers always look for practical solutions. The integration of
Evolution with Maptek Vulcan mine planning software will provide
the necessary tools. Our first project is phase optimisation, a tool
which is in high demand for finding the most practical phase design
for a schedule.”
Founded over 30 years ago, Maptek is a leading provider of soft-
ware solutions for the mining industry.
