While Grade Engineering provides new value based options for manipulating insitu grade and delivering improved productivity, it can also be perceived as creating increased complexity. A high level of user defined options and dynamic scenarios challenges current practice.
The disruptive and dynamic opportunities that coarse separation delivers through Grade Engineering® requires a more effective approach to whole of system control and execution.
The disruptive nature of having new options to applying coarse separation early in the mining and extraction cycle can appear to introduce ‘complexity’ compared to current practice. Coarse separation can be used to address a range of bottlenecks or financial targets which depend on the operating mode and maturity of individual operations (including pre-feasibility). Introduction of on-line information from coarse feed streams also introduces new data flows into control systems.
The objective is to integrate outcomes from the other Programs into management execution systems (MES) that can be used by operational decision makers to maximise efficiency and value. The dynamic nature of coarse separation as an optional process makes it especially suitable for scenario planning and options analysis.
The ultimate aim is to generate tools and knowledge that can be used to capture and manage the disruptive outcomes of Grade Engineering® as part of an overall business solution approach. This includes working with centres of expertise in organisational design and change management to ensure the benefits of disruptive new technologies can be sustained in what are often entrenched operating cultures.
