TS. Phase Adjacencies
- iarmstrong
Phase Adjacencies prevent underground mining and underground dumping. For example, you can mine Stage1 and Stage2 simultaneously, but Stage2 cannot under-cut Stage1.
Similarly, you can backfill a pit while it is being mined, but you can't dump underneath an unmined block.
Overview
Example: If two blocks are adjacent to each other in Pit1, the Stage 1 block always need to go before Stage 2, to honor the cutback design.
Phase Adjacencies only set vertical dependencies between blocks. To finish an entire stage before another, see Custom Dependencies.
Adding Phase Adjacencies
Name | Above Stages | Inner Stages | Dump → Pit Standoff |
|---|---|---|---|
Expand tree structure to the level required. | “Above Stages” should be used where there is a stage, and above it, there is another stage, but it is not nested inside. So, if StageA is set to be an above stage of StageB, in order to mine a block in StageB, you would need to mine a block in StageA on the bench above. | “Inner Stages” should be used where if there are nested pits A and B, where A is inside B, you would set StageA as an inner stage for StageB. In order to mine a block in StageB, you would need to mine a block in StageA that is at the same RL. | Set standoff distance between a dump and a pit. |
Illustration
Note, that this setup step is not for the Phases in their entirety, we don’t need to mine entire Stage 1 before proceeding to the Stage 2, it’s for two blocks adjacent to one another.
