This feature enables users to assign specific blocks to be mined within designated periods. It maps end-of-period surfaces to blocks, determining which blocks fall within each period.
Enabling Spatial Guidance
The Spatial Guidance feature is optional and can be enabled or disabled via the Use Spatial Guidance flag in Configuration Options. When enabled, a Spatial Guidance setup step appears in the Setup Task list. By default, this feature is disabled.
Settings -> Configuration Options -> Use Spatial Guidance
Configuration Guidance Sets
Guidance Sets are collections of End-of-Period (EOP) surfaces primarily used for organizational purposes. When assigning target periods to blocks, all EOP surfaces are combined into a single collection.
Creating Guidance Sets:
- New Guidance Set: Create a new, empty set to fill with EOP surfaces from layers or imported non-solid surfaces.
- Import from Micromine Beyond: Import EOP surfaces from a “.tridb” file and assign periods.
- Import from ATS End of Period Export: Import EOP surfaces from a “*.guidesnaps” file and assign periods.
Guidance Set Options
EOP Surface Setup
EOP (End of Period) surfaces represent the planned state of the pit at a specific date. Each EOP surface is assigned a period, ensuring that all blocks above it must be mined by that time.
When multiple guidance sets exist, they are merged into a single set for calculations, with each block assigned the earliest period from all sets.
Period Selection:
- Click the Period column to open a drop-down menu and choose a period.
- Scroll up to select a period Before Plan or down to pick a period outside the planning horizon.
Multi-Selection:
- Use CTRL or SHIFT to select multiple surfaces.
- Assign a single period to all selected surfaces in the lower panel.
- If multiple periods are selected, the upper field will display “(multiple values).”

Calendar Inputs
Calendar inputs allow users to control how much influence End of Period (EOP) surfaces have on the schedule.
Configuring Guidance:
Navigate to Schedule > Calendar > Guidance to adjust the impact of EOP surfaces on scheduling.
Key Parameters:
- Period Matching Incentive: Prioritizes blocks scheduled to be mined within their assigned period. Higher values increase the priority, provided the target period hasn’t been reached.
- Period Match Lookahead: Determines how many future periods affect the schedule. A default value of 1 means only the current period is considered. A value of 2 looks ahead one month. Zero is not allowed.
- Delayed Block Incentive: Increases priority for overdue blocks. The longer a block is delayed, the stronger the incentive to mine it.
Schedule -> Calendar Tab -> Guidance
Agents & Strategic Guidance Weight
In the Agents section, users can set the Strategic Guidance Weight for each agent, determining how strictly they follow the guidance.
Schedule -> Calendar Tab -> Agents
Scenarios
Users can create multiple Scenarios within the same project to compare different input outcomes, such as varying incentives and weights. For more details, refer to Schedule > Scenarios panel.
Scenarios with Varying Incentives and Weightings
Animation & Reserves Shading
In the Animation tab, users can review how scheduled mining aligns with strategic guidance.
- Reserves Shading: The default <Strategic Guidance> shading displays the target period assigned to each block.
