Creating a Pit Feature

You can create a pit according to the number of benches and the distance between each bench.

Before you begin:
  • Adjust the design range and magnitude preference options. See Customizing Preferences.
  • Adjust the color preferences for the toe and crest contours. See Toe and Crest Colors.
  • Create a product, such as a site that contains a terrain and Earth Engineering data. You can also import existing data, for example Surpac files in a product. For more information, see Creating a Site for Mine 3D Design.

  1. Optional: Insert a surface mine object in the site product.
    1. In the tree, right-click the site product, and select Insert> Extended Product .
    2. Search for surface mine.
    3. In the 3D Part tab, select the Create 3D Representation check box.
  2. Specify the working context by double-clicking the 3d shape under the surface mine in the tree.
    The UI-activated object (3d shape) appears highlighted in blue. You can now work in the context of the 3d shape.
  3. From the Surface Mine section of the action bar, click Pit .
  4. In the tree or in the work area, select the ultimate bottom plane of the pit.
  5. Specify the default value of the bench height.
  6. Determine the number of benches. From the Bench Creation options, select one of the following:
    OptionDescription
    Number of Benches Lets you enter the number of benches manually.

    By default, this option is selected.
    Up to Terrain

    Lets you select a terrain (surface) and fills-out the number of benches automatically.

    The value is associated with the terrain (surface) you selected. When the pit is processed, it will reach the terrain even if the optimized pit shell is not high enough to reach the terrain
  7. From the Naming options, select one of the following:
    OptionDescription
    Elevation

    Applies the bench elevation value, a computed distance that is:

    • For benches, the distance between the last bench support and the crest contour.
    • For bench supports, the distance between the plane of the last bench support and the current plane support.

    By default, this option is selected.
    Standard Applies an incremental value to each bench and bench support name.

The bench support planes are created accordingly. They work as reference planes to represent the contours of the toes and crests of the pit phase you envision.
