Convex Hull and Development

• Stope Reconciliation

Build convex hull to quantify the geometry of the stope including drives. This is an important measure for common loss of confinement cases e.g. concave faces and drive undercutting.

Steps

1. Adjust the best fit rotation (purple) (if required).

2. Disable boxes if aren't needed or are erroneous.

3. Main clipping box (green) fits stope.

4. Top and bottom boxes (blue and orange in the panel) capture development above/below drives.

5. Adjust controls including, max distance, box scaling, rotation, offset so that only the development closely associated with the stope is contained within these volumes.

dica

The best fit was intended for simple longitudinal stopes. Many stopes will cause the top and bottom clipping volumes to be misfit and change the primary secondary tertiary orientations. Often, it's best to disable these boxes and scale/rotate/offset the main clipping box to fit the stope. The best fit adjustment (purple) is applied before the best fit is found and assists in finding an initial solution that requires minimal adjustments.

cuidado

Jagged edges may occur if only 'Max Distance' is used. It is best to combine with clipping boxes.
