Bridging the Gap Between Strategic Plans and Operational Mine Schedules

In mine planning, the transition from strategic objectives to operational execution represents one of the most demanding challenges for planning teams. Long-term optimization tools, designed to maximize NPV, define optimal pit shells, and model life-of-mine scenarios, operate over multi-year horizons and rely on algorithms such as Lerchs-Grossmann, Pseudoflow or DBS. But these tools are not built to address the operational realities that govern day-to-day production: equipment constraints, active bench management, haulage route efficiency, or grade blending requirements at the plant.

GEOVIA MineSched, Dassault Systèmes’ short- and medium-term mine planning and scheduling software, is designed to close this gap. Operating at the tactical planning layer across months, weeks, and days, MineSched transforms validated strategic plans into practical, executable operational schedules within a single, integrated environment.

Important distinction: MineSched does not perform optimization. It focuses on scheduling, applying heuristic algorithms to achieve user-defined targets within configured constraints. The mine planner configures the planning scenario and remains responsible for validating the resulting outputs. MineSched operates within existing mine designs and does not generate them.

From Strategic Optimization to Tactical Execution

Strategic planning tools address long-term objectives such as NPV maximization, pit shell definition, and life-of-mine scheduling. MineSched operates at the next layer, translating those outputs into schedules that reflect operational realities including equipment availability, destination constraints, production targets, and spatial precedence.

The integration between these two layers is critical. A strategic plan that cannot be executed reliably at the tactical level introduces reconciliation risk. MineSched addresses this challenge by using the block model as its single source of truth, ensuring consistency across all planning stages while eliminating the need to re-import or reconcile data across disconnected systems.

The practical outcome is that a mine planner can configure a reliable base scenario in under one hour, with full auditability at every step, without relying on custom scripting or external specialist services.

Core Planning Capabilities

Pit Sequencing with Operational Safety Controls

Tactical pit sequencing in MineSched generates extraction sequences that comply with defined operational safety parameters while reflecting real mining conditions.

It allows planners to control key constraints such as the maximum number of active benches per period, ensuring safe levels of simultaneous bench exposure. Minimum mining widths are enforced to guarantee equipment access and face stability. Mining direction flexibility also supports rapid scenario comparison when ground conditions or priorities change.

Sequencing can be reviewed through configurable animations and dynamic dashboards, providing both visual and analytical confirmation that the sequence is safe and operational before field execution.

Target-Based Sequencing for Grade and Ratio Control

Short-term planning requires balancing plant feed consistency, stripping ratio, and ore blending. MineSched addresses this through its Quality Targets and Ratios module, enabling planners to define operational targets directly within the schedule.

These include blend targets to maintain consistent head grade and maximize plant recovery, a constant stripping ratio to ensure operational continuity, and material proportion targets to control the throughput of high-grade ore.

Because these targets are directly linked to the scheduling engine, the impact of sequencing decisions on plant feed can be evaluated immediately, reducing the risk of grade shortfalls and limiting unexpected processing variability.

Haulage Planning and Fleet Modeling

Short-term schedule reliability depends heavily on accurate haulage assumptions. MineSched integrates haulage planning directly into the scheduling environment.

It enables automatic route definition, generating optimal haul paths based on mine geometry and destination configurations. Explicit road and access modeling allows haul roads and bench access roads to be defined so the plan reflects actual site infrastructure.

Fleet aging simulation adjusts equipment utilization over time to reflect realistic productivity changes, while seasonal weather integration accounts for adverse conditions that impact haulage performance, reducing gaps between scheduled and actual results.

Production Priorities: Sequencing All Mining Activities

Operational schedules must extend beyond material extraction. The Production Priorities workflow in MineSched extends sequencing control to all mining activities, including drilling, blasting, loading, and hauling.

Precedence rules are automatically generated based on bench elevation, reducing manual configuration effort. Additional priority rules can be defined to minimize bottlenecks between activities.

This workflow ensures continuity between short-term and long-term planning horizons, using spatial precedence parameters that maintain consistency as the planning window evolves.

Stockpile and Tailings Dam Management

Material flow management is a key part of operational planning, supported directly within MineSched.

Stockpile capacity rules define maximum constraints for all stockpiles, with overflow management ensuring practical routing under varying production conditions. Integrated tailings modeling covers tonnages, dynamic capacities, and pulp generation, including fixed or variable recovery factors by material, grade, and commodity.

The system also supports flexible grade and metal unit configuration (g/t, oz/t, and others), aligning outputs with plant and corporate reporting requirements. Integrated reporting enables dashboards and extended reports to be generated directly in the tool, removing the need for external data processing before validation and communication.

Why this matters to your team?

The cumulative value of MineSched lies not only in its individual capabilities, but in the overall planning workflow it enables. By consolidating geology, mine design, equipment constraints, material destinations, and production targets within a single environment, MineSched reduces the data fragmentation and manual reconciliation that typically consume planning resources at the tactical level.

Auditability at every configuration step ensures that scheduling decisions can be reviewed, justified, and communicated across planning and operations teams, which is critical for maintaining confidence in the plan as conditions evolve. Rapid scenario generation and visual validation capabilities also allow planners to respond to operational changes without rebuilding the schedule from the ground up.

The result is a planning process that is faster to execute, more transparent in its assumptions, and more closely aligned with the operational realities that determine whether a schedule can be successfully achieved.
