Differential Solid Volume

Source file: query-differential-solid-volume.htm

The differential solid volume tool measures the volume difference between two solid surfaces and is useful for checking the progress of a stope as it is mined or to check a stope against design.

1. On the Underground ribbon tab, in the Analysis group, select Differential Solid Volume.

   

2. Drag the new surface into the New solid field.

3. Drag the original surface into the Original solid field.

4. If you need the results output as mass, select Calculate mass using density of and enter the material density in the field.

5. Click OK or Apply.

Both surfaces are checked for inconsistencies and the volume of each solid is calculated. Results appear in the Report Window in terms of volume and mass differences, and the areas of overbreak and underbreak. 

The pink shaded areas indicate what's been excavated against the light blue being the design stope.
