Data #10: Reserving Software Specifics

Click to Print

Note: This article is a work in progress!

The appropriate method to import/update data in a Table depends on the software used to generate reserves. No matter the method, create your Levels and Fields (through the Setup menus) before using the Import menus described below.

In addition, any time the Import Data menu option is used, you should ensure that each line of your CSV/XLS/XLSX file has a unique identifier (usually a combination of several columns such as Pit, Strip, Block, Seam and Bench) which is how Spry identifies where the other data (qualities and volumes etc.) will be stored in the Table. If nodes are unique based on the Process, you may want to import them as separate sheets in an XLS/XLSX.

Vulcan

As of Vulcan 10, the suggested method to export data from Vulcan is to use the Open Pit Solids menu. For more information about how to use these tools visit Maptek or search for Split Pit Solids.

Once a CSV/XLS/XLSX is created that references solids and required parameters use the Import ► Data menu option.

Deswik

The suggested method for importing Deswik reserves is to import the VCDL or DCF file directly using the Import ► Solids ► From Deswik Database menu option which is a single pass that imports both Solids and related attributes.

Minescape

The Minescape reserves importing process has two components and the second has two different options:

  1. Import “Accumulated” reserves (qualities, volumes etc) using the Import ► Data menu. This will NOT include 3D/Solids.
    1. Use an “Unaccumulated” set of reserves to import detailed Solids. These Solids are usually directly imported into the Table alongside Nodes created in step 1 through the Import ► Solids ► FromMinescape Unaccumulated Reserves menu.
    2. Use roof and/or floor polygons to import lower detailed Solids (faster performance, lower detail) using the Import ► Solids ► From Roof & Floor Polygons menu.

Minex

The Minex reserves importing process has two components and the second has two different options:

  1. Generate a reserves CSV (qualities, volumes etc) from the Minex menu option ReservesDB ► Reporting ► Detailed Report. Import the result using the Import ► Data menu. This will NOT include 3D/Solids.
    1. Import the Solids directly from the dbr.dat file using the menu. This method works well for most source reserves (especially for complex geology) but does not produce a surface that is cut to topography.
    2. Use roof and/or floor polygons to import lower detailed Solids (faster performance, lower detail) using the Import ► Solids ► From Roof & Floor Polygons menu. This works well for dump reserves as well as dig reserves with simple geology. Export the polygons from Minex using the menu option ReservesDB ► Export ► Pit Polygons option.

Roof and Floor Polygons (various sources)

This menu option expects at least one (but potentially several) CSV files that contain ordered lists of X Y Z points. Run by selecting Import ► Solids ► From Roof & Floor Polygons and selecting the CSV file/s.

roof floor polys

If you have only a Roof or Floor file (as opposed to both) you may need a set of Horizons similar to the screenshot above, otherwise a single entry with a way to distinguish between roof and floor is sufficient.
