This command will assign key thickness, non-key thickness and
key tonnage grid files to a series of pits or timing blocks. This
is an alternate manual way of assigning grids instead of through
the Output Thickness Grids option in the Surface Mine Reserves.
These grids are associated with a bench number and stored in the
pit polylines. This data is used by the Surface Equipment Timing
routine, and these three values are required. Optionally attribute
quality grids can be assigned here for each bench. You can use the
Pit Report or Edit Pit routines to verify which grids are assigned
for each bench. The key tonnage grid is tons/square foot or meter.
It is easily made with the thickness grid and a density grid in
Grid File Utilities. For example: Thickness Grid (feet) x Density
(tons/cubic foot) = tons/square ft. The following dialog box allows
for interactive entry so all benches can be entered and viewed
together as one step. The blue colored text represents required
attributes and the black colored text represents optional, user
added attributes.
