As outlined in SC. Domain Mappings, Spatial Conformetrics looks at the intersection of a Production solid and a Schedule solid.

To generate these solids, a set of Start and End Surfaces needs to be defined for each solid type. These surfaces can be specified inside a Surface Set.

Multiple Surface Sets can be created, which is useful when different pits have different production surfaces.

Creating Surface Set

  1. Press the blue plus button located in the toolbar of the Surface Sets panel.

  2. Give the surface set a meaningful name, i.e., "Pit1/Stage1".

  3. Provide the relevant surfaces by dragging the surface from the Layers panel or loading it in via file by clicking on the black downwards pointing arrow at the end of the cell.

Adding surfaces to the Surface Set

Production and Schedule Surfaces

A description of the surfaces that can be loaded is shown in the table below.

The conformance domains used downstream are generated from the intersection of the resulting Production and Schedule solids, so it is important to use the correct Start and End surfaces.

Production Surfaces

A production volume is defined by a start surface and an end surface.

  • If the start surface is higher than the end surface, it is a cut volume.

  • If the end surface is higher than the start surface, it is a fill volume.

  • If neither surface is higher or lower (because they are equal, or because one is missing), then there is no production volume at this location.

Production Surfaces

A production volume is defined by a start surface and an end surface.

  • If the start surface is higher than the end surface, it is a cut volume.

  • If the end surface is higher than the start surface, it is a fill volume.

  • If neither surface is higher or lower (because they are equal, or because one is missing), then there is no production volume at this location.

Production Start

Survey surface from the opening date:

Production End

Survey surface from the closing date:

Schedule Surfaces

A scheduled volume is defined by a start surface and an end surface.

  • If the start surface is higher than the end surface, it is a cut volume.

  • If the end surface is higher than the start surface, it is a fill volume.

  • If neither surface is higher or lower (because they are equal, or because one is missing), then there is no scheduled volume at this location.

Schedule Start

Plan depletion surface from the opening date:

Schedule End

Plan depletion surface from the closing date:

Schedule Future

(Optional) Plan depletion surface for the next period.

May be used to distinguish between over-dig and out of plan movement. This is used to generate two schedule solids: a "planned now" and a "planned later" solid. 

  • Production volumes inside the "planned now" solid are classified as cut in plan.

  • Production volumes inside the "planned later" solid are classified as over dig.

  • Production volumes outside both solids are classified as out of plan.

The Schedule Future surface may be used to differentiate between "Over Dig" and "Out of Plan" material. See SC. Domain Mappings for more information.

Shared Surfaces

Sometimes it is assumed that the Schedule Start and the Production Start are the same surface.

If this is the case, leaving the schedule start as blank will automatically set Schedule Start = Production Start.
