Command Overview

Calculate a blast volume based on input top, bottom and pit surfaces, using the Calculate Blast Volume dialog.

Command Steps:

  1. Run the command.

    The Calculate Blast Volume screen displays.

  2. Select a Current Pit and Current Area using. These represent top-level folders in your Studio Survey database.

  3. Enter or select a Blast ID. This is a unique identifier for a blast and typically follows a standard naming convention.

  4. Select both the Survey Date and Date Fired.

  5. Specify the name of the Surveyor from whom data used in the volume calculation was received.

  6. Select a name using the Calculated By drop-down list. This is typically you.

  7. Specify the Blast Outline configuration:

    1. Pick a Blast Outline object. This data was added to the database with specific meta data using the Add to Database (Open Pit) screen previously.

    2. Choose the attribute in the string file that denotes individual blast outlines.

    3. Choose the blast outline value.

    4. Click Get to retrieve the blast outline from the database and populate the remaining blast outline screen items.

      Note: Alternatively, click the browse (...) button to locate any Datamine string file to use as a blast outline. This can be within or external to your Survey database.

    5. If you need to, edit the outline in the 3D window using the tools provided (or, in fact, any of the digitizing tools in your product).

    6. Pick the Designed Pit Strings for a visual reference. These aren't actually used to calculate the volume of the planned blast. Once picked, load these into the 3D window using the arrow button.

  8. Specify a Top Surface, either a collars or points file.

  9. Choose the Minimum distance inside perimeter; this is the distance between the blast outline and the peripheral blast holes. Click Clean to apply the constraint.

  10. Specify a Bottom Surface:

    • Define the bottom of the blast using a reference level (Blast RL).

    • (Optionally) choose a Pit blast bottom surface that exists in your database.

    • (Optionally) choose a Designed pit surface that exists in your database.

  11. (Optionally) as a visual reference, select a Surveyed Pit Surface. Whilst this data doesn't affect the calculation of a blast volume, it can be useful to give the blast outline useful context.

  12. Click Calculate.

    Output volumes are created, and an Excel and PDF (or .emf if no PDF write exists) file is generated in your Survey database.

  13. If you wish, you can Use a fixed plot scale. If checked, all plotted items will honour the scale set.

    Tip: This can be useful if projections on your report relate to the same data in different views.

  14. To generate evaluation results as part of your report (it's optional), you'll need to specify a suitable block model:

    1. Enable Use block model for reporting.

    2. Use the "..." button to display the Block Model Options pop up.

    3. Fill out the fields on the Block Model Options screen and click OK.

      See EOM Report Block Model Options.
