Bench Offsets may be used to force a delay and minimum or maximum vertical lag between phases.
Setup > Bench Offsets
To add a Bench Offset:
Press the blue plus icon to add a new rule group.
Rename the rule group (i.e. mining rules, backfill rules, land-bridge rules).
Using the tree hierarchy on the right, select the successor record and double click on the predecessor.
Set the delay in hours.
Set the Vertical Offset in metres:
Negative to keep the successor elevated over the predecessor
Positive to keep the predecessor elevated over the successor
Verify the dependencies in the Preview panel.
Every bench at elevation (E) in the Successor stage is made dependent on the bench at elevation (E+Offset) in the Predecessor stage. Offsets may be positive or negative.
