Mining solutions developer Maptek has re-launched the open pit scheduler which it acquired from Orelogy in 2014, as Maptek Evolution.
Maptek 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 genetic 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,’ said Maptek Mine Scheduling Manager Steve Craig. ‘Many iterations are run to analyse the most relevant solution for a particular set of data inputs and operating 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,’ continued Craig. ‘This optimisation accounts for the complex geo-metallurgical environment, 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 engineers 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 landforms. 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’, he 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.’
Recent sales in South America represent a significant milestone for Evolution, affirming its place among Maptek mining solutions.
