Strategic Mine Planning & Optimization

Software: Geovia Whittle and Excel Solver

The Strategic Mine Planning and Optimization course is a comprehensive five-day course designed for mining and resource industry professionals including directors, project managers, mine planners, mining engineers, geoscientists, geologists, managers, metallurgists, financial analyst, and decision makers from exploration to operations. It is ideally suited to those from industry who wish to gain a more in depth and hands-on knowledge of modern strategic mine planning and optimization software tools and theory. Strategic mine planning optimization process is the backbone of mining operations. In mining projects, deviations from optimal mine plans will result in significant financial losses, future financial liabilities, delayed reclamation, and resource sterilization. The lifeof-mine production schedule determines the order of extraction of materials and their destination over the mine-life. In this course, principles and fundamental concepts involved in strategic mine planning and optimization are presented. Subjects covered are block value calculations; mining revenues and costs; open pit limit optimization using manual method, floating cone, and 2D & 3D Lerchs and Grossmann algorithms; Pseudo Flow algorithm, life-of mine production planning; mine-life estimation; cut-off grade optimization and Lane’s theory; simultaneous optimization; multi-mine multi-process production scheduling, and an approach to managing grade uncertainty. Mathematical optimization models and case studies for long-term open pit mine planning will be presented. Blending problem formulations are setup and solved in Excel Solver. The course complements theory with comprehensive instructions and hands-on experience completing a project using GEOVIA Whittle strategic mine planning software. Comparative analysis of different production scenarios, stockpiling, cutoff optimization, SIMO, multi-mine and their impacts on the bottom line of the mining business is illustrated.

Open Pit Mine & Dump Design

Software: Geovia Gems

Open Pit Mine Design is a two-day course designed for mine planners, mining engineers, geologist, and people who are responsible for activities that require them to design and manage pits, ramps, switchbacks, slots, and waste dumps. The participants will complete a pit-design project during the course. The course covers open pit design terminology, selection of loading and hauling equipment based on targeted annual production, working and safety bench geometry calculations, haul road parameters and geometric design. Prior to engaging in pit design, the course reviews principles and fundamental concepts in creating points, polylines, and triangulations; generations of plans and sections; also surface and solid modeling for the purpose of open pit design. The course includes a step-by-step project for top-down and bottom-up pit design. The project starts from the final optimal pit shell, intermediate pits shells, and the long-term schedule generated in Whittle. It covers topics on how to choose the required parameters such as berm width, variable pit slope angle, and batter angle to achieve a desired pit and dump design. The project continues with creating surface triangulations from the pit design, obtaining volumes, tonnages and grades reported by bench, rock type and grade range from the designed pit.

Outcomes of the course include:

• Understand pit design parameters & components

• Understand pit design theory

• Use optimal pit shells in pit design

• Select loading and hauling equipment

• Define Bench geometry as a function of equipment specs

• Understand haul road design

• Design of toes, crests, ramps, switchbacks and slots

• Define berm width, pit slope angle and batter angle

• Create final pit designs and surfaces from the designs

• Obtain volumes, tonnages and grades reported by bench

• Design variable pit slopes

• Handle multi-benching

• Manage single-pit splitting to multi-pits

• Design variable pit slopes based on rock-types

Medium/Short-term Open Pit Mine Planning

Software: Geovia MineSched

Medium / short-term open pit planning is a three-day course designed for the mine planners, mining engineers, geologists, and technical managers who are responsible for activities that require them to generate or oversee monthly and weekly mine production schedules. The course is designed to provide theory through lectures, complemented by a hands-on real-world mine planning project using GEOVIA MineSched. The project covers all the required steps from a long-term yearly schedule generated within a designed pit to a monthly production schedule taking into account mining and processing capacities, truck-shovel hours, drilling and blasting, blending, and stockpiles management constraints. Mining constraints can be applied to ensure that practical schedules are generated. Learn how to model and manage stockpiles and processes, block modeled waste dumps followed by automated filling strategies and waste scheduling. Also, reporting and 3D visualization of a spatial database of the materials within the waste-dump, which is critical for both long-term waste dump management and reclamation. The course covers the following topics:

• Medium/ short-term planning concepts

• Data preparation

• Parameters: rates, delays, priorities

• Quantity and quality targets

• Defining mining locations

• Defining process streams

• Period polygons: tonnage/grades

• Reporting: Excel, Access, MS Project

Simulation of Mining Systems using Arena

Fundamentals of Discrete Event Simulation (DES) modeling and its industrial applications to mining and processing systems are presented. Theoretical and statistical aspects of simulation, including input and output analysis, experimental design, and variance reduction techniques are presented. Arena Simulation Environment (by Rockwell Automation) is used as the primary modeling simulation tool for explaining simulation concepts. The course focuses (three days) on modeling detail truck-shovel simulation models that uses the historical dispatching data, road profiles, and short term mine plans as input into the simulation model. The simulation models need to be calibrated, and verified to link the short-term mining schedules to the operational plans in presence of uncertainties of cycle times, scheduled and unscheduled down times, shift changes, etc. The rest of the course will focus on combined continuous and discrete-event simulation of processing systems. Size classifications including sieves and hydrocyclones; comminution operations including crushing machines, grinding, and semi-autogenous mills; solid-liquid separation including thickeners and filtration; and also gravity and magnetic separation modeling will be covered by examples. The course is intended for mining and processing engineering disciplines and participants who would like to use simulation to design and optimize real-world mining systems. On completion of this course, successful attendees will have an in depth understanding of principles and methodologies, of discrete event simulation. Also, they will be able to use Arena Simulation Software (Rockwell Automation) as the simulation modeling tool for simulating and optimizing real world systems.
