Assign Timing Grids

Function

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. 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.
