Surface Mine Scheduling - Tactical Planning


Two Courses - 8 days


MINP 301 - Surface Mine Production Scheduling GEOVIA MineSched™ Core

MINP 302: Compliance of Strategic and Tactical Mine Plans - Advanced MineSched and Isight

Who Should Attend

Medium / short-term open pit planning is an eight-day training split over two courses, 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 and SIMULIA Isight. 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. 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
    •  Alignment of short-term plans with strategic plans
    •  Parameters: rates, delays, priorities
    • Quantity and quality targets
    •  Defining mining locations
    • Defining process streams
    • Period polygons: tonnage/grades
    • Reporting: Excel, Access, MS Project
    • Animations & presentation tools

Course Description

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.
