Constraint

Use the tools on the Mining | Pit Design (Dynamic) tab, in the Constraint group: to add and create a base for the design or add the next bench.

• Click New Base to add a new base polygon from which to build the pit design.

• Click New Base | Add Base to add an existing polygon as a base from which to build the pit design.

• Click New Flat Area to create a new flat area (external) constraint polygon.

• Click New Flat Area | Add Flat Area to use a selected polygon to define the flat area.

• Click New Pillar to digitise a polygon to define a pillar (internal) constraint.

  

  Note: This tool will change to New Internal Pit for Down direction mode.

• Click New Pillar | Add Pillar to add a selected polygon to define an internal pillar.

  

  Note: This tool will change to Add Internal Pit for Down direction mode.

• Click Add Pit Limit to apply a selected draped string to constrain the pit by cutting away any area outside the constraint.

  

• Click Add Pit Limit | Add Exclusion Zone to apply a selected draped string to constrain the pit by cutting away any area inside the constraint.

  

• Click Constraint List to open, manage and edit a list of all of the constraints in the design.
