Input
Input (Pit Solid)
Input is typically a pit solid. Parameters in the form define the grid size, orientation and the bench levels. Running the function generates indexed mining block solids (wireframes). For an overview, see: Create Mining Blocks
To assign material grade bins to each block, the Grade Tonnage Report has been enhanced to enable multiple grade categories to be written to a wireframe. The feature, used to do this, is called a material set.
To process a single wireframe:
- Select the Single option. Select the type of the wireframe, and then the name of the wireframe.
To process multiple wireframes:
- Select the Stages option.
A check is made that the input wireframes are valid.
Stages
Enter the list of incremental, non-overlapping, closed wireframes (solids) that define the stages. The wireframe for each stage must exclude the material that has been included in any previous stage.
Wireframe
Double-click or click on the List icons to select the wireframes you want to use as inputs.
Output
In the Output column, specify the names that will be assigned to the wireframes created from each input wireframe. Use the buttons on the local toolbar to Manage the rows in the list.
Mining Blocks
Choose how small mining blocks will be handled. There are two options:
-
Discard when block volume less than
Select this option to discard blocks with a volume smaller than the specified volume.
-
Merge when block volume less than
Select this option to merge adjacent blocks with a volume smaller than the specified volume.
Note: These options should be used with caution when the mining blocks are being generated for use with the Scheduling | View | Interactive Dependencies | Vertical by Index tool. The index for each mining block (Block Index) is generated in the format XXXXYYYYZZZZ, where XXXX, YYYY and ZZZZ are the column, row and layer indexes respectively for the mining block based on its position within the 3D cutting grid.
The dependency generation tool relies on these indexes to determine which mining blocks must be removed to access each mining block. If blocks are merged within the grid, the corresponding dependencies may be too constraining. If blocks are discarded from the grid, the dependencies may be incomplete.
