MINING SOFTWARE for exciting advances in 2017. New tools in Maptek Evolution improve performance of mine scheduling processes and deliver greater project value. Evolution 4.5 features the stunning new graphics environment which already provides Maptek I-Site, BlastLogic and Eureka software users with a superior visualisation experience.”
Johnson says that the high performance graphics engine can display and manipulate large models of up to millions of blocks, along with the solids and triangulations that make up those blocks.“ Scheduling is about ensuring value of your assets can be maximised at a strategic level. It is also crucial to ensure these plans are practical and can be implemented in a more tactical, shorter time frame. Evolution Strategy and Origin allow the engineer to achieve practical, high value schedules that can be implemented at a production level. Mines are complex environments and scheduling production is just as complex. Planners must consider cut-off grade, route and equipment allocation, cycle times, fuel burn and waste dump locations. Maptek products help present an integrated, holistic 3D view of a minesite by simultaneously displaying multiple models, waste dumps, haul networks and topography.”
Evolution Phase is a new member in the family of Evolution products, allowing the engineer to build practical phases from a series of optimal shells very quickly, and rapidly cycle through this process to ensure value is maximised from pit optimisation through to schedule optimisation.“ Evolution Strategy maximises net present value and generates cut-off grade optimisation policies. New options allow users to build blend constraints and to track and report multiple elements and contaminants per process and / or destination. Existing stockpiles can be modelled with tonnes and grade items.”
A global minimum cutoff can be specified, as well as minimum and maximum accumulation constraints for multiple processes. Users wanting to run Strategy without cutoff grade optimisation can fix their own cutoff grade policy. The optimisation process then determines the best

extraction sequence for that setting. Importantly, this feature can be simply turned on and off on to determine the value adding capability of running with cutoff grade optimisation. Most cases show a significant uplift in value of up to 25 %.
Evolution Origin generates detailed scheduling scenarios from life-of-mine to short term planning horizons and can apply optimisation policies generated by Strategy. Users can set maximum constraints per stage / group / period for manipulating sequences through the model.
