Benches
The Benches tab relates to the vertical definition of the pit. The Z value of each bench is defined in a grid list. The radio buttons at the top of the tab determine if these Z values represent the crest, toe or midpoint of the bench. The Bench Name is used to construct the name of each mining block wireframe. It will usually be a whole number, incrementing by the bench height. Both the Z value and/or the name can be written as (“Bench Z” and “Bench Name”) attributes to the wireframes.
Note: There is no need to manually type in this information. The rightmost icon on the grid list toolbar will pop up a dialog with parameters to automatically generate all the bench values and names. The start value and the number of benches have a calculate option that will populate the response field based on the pit wireframe.
Z values
Specify whether the Z values used to define the benches represent the crest (the default), mid bench, or toe of each bench.
Bench Z and Bench Name
Use the grid to enter the z value and the name of each bench. You can use the buttons on the grid list toolbar (or use the right-click menu) to Manage the rows in the list.
