Calculating the Differential Solid Volume

The Differential solid volume option 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 Query ribbon tab navigate to the Surface group and select Differential Solid Volume.

   

2. Drag and drop the new surface into the New solid.

3. Drag and drop the original surface into the Original solid.

4. Specify the density to be used to calculate the mass.

Both surfaces are checked for inconsistencies and the volume of each solid is calculated and reported in the Report Window in terms of volume and mass differences and te area o overbreak and underbreak. 

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

Example of a report displayed in the report window.
