TS. Phase Adjacencies
- iarmstrong
Overview
Phase Adjacencies prevent underground mining and underground dumping. For example, you can mine Cutback1 and Cutback2 simultaneously, but Cutback2 cannot under-cut Cutback1. Similarly you can backfill a pit while it is being mined, but you can't dump underneath an unmined block.
Example: If two blocks are adjacent to each other in Pit1, the Stage 1 block always need to go before Stage 2, to honour 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 A is set to be an above stage of B, in order to mine a block in B, you would need to mine a block in A 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 A as an inner stage for B. In order to mine a block in B, you would need to mine a block in A 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.
