Stockpile Volume

This option computes the volume of a stockpile given a boundary string around the base of the stockpile. The boundary string can in fact be any closed string, it does not need to be actually entered as a BOUNDARY string. Note: the program has a restriction and will only allow one Boundary string to be entered.

The program will first form the lower surface model using the points on the boundary string of the stockpile. It will then form the upper surface model using all the points inside the boundary string and compute the volume of each triangular prism formed.


The results will be displayed on the screen and optionally written to the listing file.

Points to Note
Process
  1. Ensure stockpile bases have a single closed string.
  2. Inspect data, triangulate model, contour at 0.1m and resolve any errors.
  3. Review triangles and ensure there are no ‘holes’ (shade triangles).
  4. Topo>>Stockpile Volume. Click on stockpile base string.
  5. Choose listing file (*.LST) – this is advisable, though not mandatory.
  6. Click “compute”.
  7. Refer to *.LST file or copy/paste report into email or acs file as necessary.
  8. Verify volume report using a common-sense approach such as calculating surface area x average height and via an alternative method such as ‘between surfaces.’
