Dynamic Haulage
Overview
The Dynamic Haulage step uses flags in Haul Infinity to open and close roads when triggered by certain conditions.
To add dynamic haulage to a project, go to the Haul Infinity tab > Network tab > Flags panel (for examples on how to add flags see Flags). Make sure that the flag is ticked in the segment properties of the relevant roads.
Constraint Types
From the Type drop-down you may select the following constraints:
None |
No constraints applicable. |
|---|---|
QuantityConstrained |
Adds rows to the calendar to trigger road closure when material movement is greater than threshold. |
Trigger |
In Configuration column set for either Start On or Start Off initial flag state: AnyMined - The trigger is fired when any ONE of the blocks specified finishes mining, AllMined - The trigger is fired when ALL blocks specified have finished mining. |
OnOnlyWhen |
Keep a road closed except for a particular combination of Periods, Agents, Source Records, Parcels and Destinations. |
OffOnlyWhen |
Keep a road open except for a particular combination of Periods, Agents, Source Records, Parcels and Destinations. |
Note: The OffOnlyWhen and OnOnlyWhen flags apply only to movements of Records that match the selected criteria — they do not affect other Records moving at the same time.
For example, if a ramp is set to OffOnlyWhen with Source selection from Stage 1, the ramp will be closed only when those Source Records are being moved. Other Records — such as those from Stage 2 — will still be able to use the ramp unless they are also covered by the same condition.
If your intent is to block or open a road based on any movement happening during a certain time (not just specific Records), consider using a Trigger instead.
