The estimation of grades in complex geological deposits presents challenges to experts in geological modeling. Traditional interpolation methods are based on distance and direction. In folded deposits, grades must be related to distance relative to the deposition time, before deformation. It is known that grade estimation is the foundation for calculating reserves and mine planning. If the geology is not well understood and your construction methods are not adopted correctly, serious financial losses will occur. For the estimation of these types of deposits, Hexagon Mining | MineSight developed the Relative Surface Interpolator (RSI) and MineSight Dynamic Unfolding (MSDU) tools. A case study was carried out in a complex geological deposit of Tenke-Fungurume, in Africa, which requires an interpolation method that best fits the genesis of mineralization. In this study, a…

In today's Tips & Tricks, we will present the best tool for determining routes and sizing fleets within mining sequencing. Dynamic Haulage is a MineSight Scheduler Optimizer (MSSO) tool that provides a more accurate solution for defining the route of cuts based on the assumptions and restrictions imposed by the user. Dynamic Haulage guarantees the best and most efficient route to destinations, taking into account previously plowed areas and economic parameters, in this way, the generated routes are in accordance with the shape of the pit, according to the advances already made. The following image shows an MSHaulage route (yellow line) on a pushback that has already been mined and is therefore unavailable. The definition of cycle time is fundamental for fleet sizing, which represents a significant part of CAPEX and OPEX. When performing the definition of routes within the…

In today's Tips & Tricks we are going to talk about how to perform blending using the MineSight Scheduler Optimizer (MSSO), creating restrictions on mass, grade, materials and even creating a restriction between the ratio of grades. All these parameters can be created in MSSO quickly and easily, generating optimal operational sequencing for your mine to maximize your NPV! MSSO generates long-term and short-term sequences that solve optimization and blending problems. These sequencing represent the most productive mining, obtaining results that reach the objectives within mass, geotechnical, equipment, economic restrictions, among others. The project flowchart is customizable, being determined the pit, the waste and stock piles and the plant in the way the user wants. The MSSO will calculate the amount of material moved at its respective…
