Overview
To generate conformance solids, the software calculates the intersection of a production solid and a schedule solid, then cookie-cuts the results by the boundary polygon of each solid. The resulting volumes are referred to as conformance domains.
Any intersecting volume is "mined in plan".
Any production volume outside the schedule boundary is "mined not planned".
Any schedule volume outside the production boundary is "planned not mined".
Any production volume above or below a schedule solid is "mined late" or "over dig".
Any schedule volume above or below a production solid is "mined early" or "under dig".
Different organisations may choose to report these volumes in different buckets, or with different names. The Domain Mappings step allows any conformance domain to be given a reporting name and colour to match company standards.
Domain Mappings are displayed on the cross-section diagram.
Note: If material is neither mined or scheduled to be mined in the current (or future) period it will not be reported
Conformance Surfaces
Start surfaces and end surfaces are input by the user in Setup > Polygons > Properties per polygon.
Start and end surfaces are specified for each polygon.
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.
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.
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.
Schedule Future Surface
A fifth "schedule future" surface 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.
