Cut Reporting

Use Cut Reporting to reconcile planned mining polygons with end-of-period polygons and create a map of planned shapes inside a polygon.

This option does two primary things:

1. Boolean a set of mining polygons against another polygon.
2. Calculate and/or report on values from data stored with the polygon (standard object attributes like Value, Name, Description, Group as well as extended data (metadata)) - with the ability to select whether the object information is simply a display value (name) or a sum value (tonnage) or an average variable (grade in the Value field). The sum variables would be a proportional value based on the end-of period.

Instructions

On the Grade Control menu, click Cut Reporting to display the Select By panel.

INPUT:

Input (with those items required for the first version of this option marked with circle bullet point vs. a square bullet point for secondary functionality):

Mining Polygons (usually an output from, for example, Grade Control)

Pick from the screen; or select (browse) for a dgd and layer with the ability to use a wildcard for layer

End-of-Period Polygons (a digitized representation of the mining for the end of a period)

Pick from the screen; or select (browse) for a dgd and layer with the ability to use a wildcard for layer

Bench Definition

Mining Polygon elevation defines the bench; or - End-of-Period Polygon elevation defines the bench; or define the 'Bench definition' as it is done in the option for Open Pit > Bench Volumes on the Bench Definition tab.

Note For the first two options you  would need to define where the mining polygon sits on the bench (Toe, Mid-bench, Crest) and the bench height.

Variables to Report

Tonnage calculation based on Tonnage Variable (selected attribute field by the user; or Tonnage calculation based on a density (user entered or attribute of the mining polygon).

Variables to sum

Variables to weight average

Display variables (e.g. text variables)

OUTPUT:

The results would include:

Polygons

Overlap/boolean of the mining polygon(s) with the end-of-period polygon(s) on a bench-by-bench basis with the attributes from the mining polygons carried over to the resulting polygons.  Note that this is the intersection of the mining polygon(s) and end-of-period polygon(s).

Saving of polygons

To a dgd and layer specified by the user (no dgd entry = stored to current dgd); or to a dgd specified by the user and layer(s) with the name specified by fields with the ability to use multiple fields to make up pieces of the layer name.
