Horizontal by Index
For open pit mining, vertical and horizontal dependencies are created manually based on the block model, bench and stage attributes you have imported as part of a long-term plan.
Certain application functions, such as the Create Mining Block tool, generate a Block Index attribute. This attribute acts as unique block identifier that delineates the location of each block with respect to other blocks. As a result, this tool can be used to create links between tasks that do not abut.
