This command calculates the volume of the spoil based on the selected grid surfaces. There are options to select the Top Fill Surface, Bottom Fill Surface and two optional top and bottom of bench grids. This command needs to be run separately for each bench to calculate the volumes for each one. The volumes are automatically stored in the spoil polylines, ready for the timing process. They can be verified and edited with the command Edit Spoil Volumes.
The following example shows how to store volumes for two
benches. The required surfaces are set by picking the top of the
pile elevation of 4850, and the bottom of the pile, stacked onto
the original Surface Topography grid. Bench 1 will be from the top
of pile, also 4850, down to 4825 elevation grid. Bench 2 will then
be from 4825 elevation to the bottom surface, the Surface
Topography grid. The Report Formatter window
displays the available attributes to report, such as Spoil, Site
Name, Bench#, Fill in CF, CY or CM if metric.
The report can be viewed with the
Display button, or taken into Excel with the export to Excel
option.
