Create Mining Phase Solids

To access this task:

Activate the Reserves ribbon and select Phases | Create Solids

Studio OP uses "Phase Solids" within the process of constructing the mining reserve solids. A phase solid is a closed wireframe that represents an individual pit phase (or pushback).

Phase Solids are generated from the intersection of the pit topography with the Phase DTM. To generate a phase solid both the the topography and the Phase DTM must have been defined.

The process for creating phase solids is to select the pit to which the resulting solids will be relevant, then specify the topography surface.

You will then have access to all of the phase DTM definitions as created by the previous task. As with that task you can select one or more definitions and create/recreate the solids for those items, or you can insert an existing solid volume into the list, based on an existing phase DTM definition.

Using the displayed table, you can either select a table row and Create a single phase solid, or elect to Create All phase solids for all pit phases (see below for more guidance).

Phase solids can be (optionally) spliced into phase-strata-solids, using the Strata Solids task, although this does rely on strata volumes being defined up front (Define Strata).

Creating Contiguous Phases - Phase Order

Solids must be created in sequential/mining phase order:the initial phase solid for the pit - the smallest volume - must be created before any subsequent shells can be calculated. This is because the volume created by phase 1, for example, will need to be removed from phase 2 to create a series of pushback solids that replicate the evolution of the pit over time.

As such, the Create button will only be enabled if either a) the phase is the first in sequence or b) the previous phase solids have already been created. The Create All button will generate all phases where a contiguous sequence of phases can be generated.

Field Details:

Pit: select the pit to which your phase solids will belong.

Topography: the topography currently associated with the selected pit (Surface Topo task) is listed here. You can toggle the display of the topography surface using the check box.

Phase Solids Table: the main table shows previously-defined phase solids, showing:

Phase: the automatically assigned index number for each defined phase.
DTM: the name of the phase DTM (as defined in the previous step) that has been/will be used to create a solid volume for that phase.
Solids: if solid volume data has been generated for the phase DTM, the name will appear in this column. Select or disable the check box to show/hide the wireframe data in the 3D window.
Pit DTM: another DTM file, this one describing how the topography would look after the current phase solid has been extracted from it.

Remove solids with volume below: Any individual solid that is generated by the intersection of the Phase DTM with the topography with a volume below the amount specified is automatically removed. This allows insignificant and unmineable volumes to be ignored.

Remove solids with maximum thickness below: Any individual solid that is generated by the intersection of the Phase DTM with the topography with a thickness below the amount specified is automatically removed. This allows very thin and unmineable volumes to be ignored.
