Strategic mine planning is the process of integrating and aligning with the strategic objective(s) of the mining company. It involves continuous adjustment and dynamic changes within and outside the mining environment. It needs to make enough room for all levels of the company, such as the corporate level (vision, mission, feasibility) and the expansion of production, as well as accounting for a medium/long term production strategy. This can be done by varying the input parameters (economic, social, political, environmental etc.) in a flexible mine planning system to achieve the desired balance between financial and physical returns. It focuses on analyzing technical variables that affect the life of a mine and the value of the underneath mineral resources until the mineral of interest is thoroughly exhausted, exploited or abandoned.
In this course, the individual will learn the diverse areas of the GEOVIA Whittle and GEOVIA Surpac in carrying out an open pit optimization coupled with detailed pit design. The individual would learn how to explore the software, considering vital factors such as: the deposit’s geological setting and topography, grade distribution, the cut-off grade, the mineral resource and reserve, the geotechnical constrains holding bench height, berms and slope stability, environmental constraints; mining and processing costs, recovery and metal price.
This course is intended for mine planners, mining engineers, geologists, and technical managers who are responsible for activities that demand them to generate or oversee yearly, monthly and weekly mine plans and designs.
The course seeks to practically and technically walk the individual through validating the required geological parameters in the block model, adding cost and slope information to the model, testing resource model and generating reports for export files validation in surpac, preparing and exporting a mod and par file, having a quick and thorough tour of Whittle interphase through importing and validating the mod and pad files, slopes input, optimizing and producing pit shells, running operational scenarios, performing analyses and scheduling using different graphs types for final pit selection as well as exporting pit files back to Surpac for detailed pit designs, further scheduling and analysis.
