#6 Direct Block Scheduling -> EOP Surfaces -> Pit Designs -> Incremental Solids -> Mining Blocks

Summary

  • Run #1: Direct Block Schedule.

  • Create cumulative solids for selected end-of-period (EOP) pit shells.

  • Create pit designs for EOP cumulative solids.

  • Create incremental solids for pit designs.

  • Cut incremental solids into 3D grid of mining blocks split by pit design boundaries.

  • Calculate attributes from block model.

  • Use grid indexes to determine task (mining block) dependencies.

Steps

  1. Run #1: Direct Block Schedule

    • Export end-of-period (EOP) surfaces for which pit designs are required

      • Scheduling | Schedule | Export | End-of-Period Surfaces

        • Set Period attribute = attribute containing period to which scheduled tasks are assigned

        • Press Autofill the grid icon button in top right corner of grid list

        • Set Start period and End period to required range of period numbers

        • Press Delete Row(s) icon button to remove rows for unrequired periods

        • Set Output Wireframe > Type = EOP Surfaces (for example)

    • Create cumulative solids for selected EOP surfaces

      • Mining | Task Preparation | Incremental Solids

        • Set Surfaces > Topography to topographic surface

        • Add Surfaces > DTM/Contour for each surface required from EOP Surfaces wireframe type

        • Set Output > Cumulative Solids to Type = EOP Cumulative Solids (for example)

  1. Create pit designs for each end-of-period (EOP) cumulative solid

    • Set Setup > Topography = topographic surface

    • Set Guides > Adjust to Optimised Shell Boundary = Type and Name of EOP cumulative solid

      • Select Show Contours

    • Complete pit design for EOP cumulative solid

    • Select Export | Export Pit Strings

      • Set File = name of file to contain pit design strings for EOP cumulative solid

  1. Continue from Step 4 in #5 Pit Optimisation -> Nested Pits -> Pit Designs -> Incremental Solids -> Mining Blocks
