Edit Manual Dependencies

To access this panel:

  • The Manual Dependency Editing group of controls is found on the Dependencies panel.

This section of the Dependency Editing screen is used to interactively generate rules that will govern calculation of a sequence of mining activities.

Note: You can also set up automatic dependencies.

Important: Design data must be loaded in order to define manual dependencies.

Manual dependencies are created by linking activity points interactively, selecting the predecessor and the successor of the dependency in that order. See Manual Dependencies for more background information.

The general procedure for manually creating dependencies is:

  1. Load design data and rotate and zoom the view to show the area of interest (activity points and string directions will automatically be shown).

    Tip: Orient the view so that all areas of interest are visible (particularly, the activity points representing the predecessor and successor of each dependency you wish to define).

  2. Define a Layer on which to add the dependency (if it doesn't already exist). These layers are predefined. See Dependency Layers. Select the layer on which to apply the new dependency, using the drop-down list.

    Note: Dependencies layers can be created using the button at the top right of the screen.

  3. Scroll down to the Manual dependency editing section of the screen. This contains the following Dependency Defaults controls:

    1. Select the dependency Layer containing the dependency to create or edit.

    2. Select the activity relationship, using the Link Type list. See "Manual Dependency Editing Methods", above, for more information on different activity relationships.
    3. If required select the amount of Delay (and unit) between the two activities to be selected. This could be useful, say, to plan a shift change contingency, for example.
    4. Select the Time unit to which the Delay corresponds.

  4. Either draw one or more Discrete dependency strings, or a Continuous dependency string to accommodate a chain of activities. See "Manual Dependency Editing Methods", above, for more information on the different dependency assignment methods.

    Tip: Use the quick keys "ddd" to enter discrete dependency drawing mode, or "ddc" to enter continuous dependency drawing mode.

  5. Cancel the editing mode when all dependencies are defined.

  6. Select Apply Defaults if you need to reset the current dependency layer to default settings. This will remove previously applied customizations.

    Tip: Use the quick keys "ddf" to enter dependency defaults application mode.

  7. If required, modify existing dependencies:

    • Reverse the direction of a dependency. After clicking the button, select the dependency to affect.

      Tip: You can also use the quick keys "dre" to launch dependency reversal mode.

    • Move From Point or Move To Point and select a dependency. Next, select the activity that will become the new start or end position of the selected dependency. Alternatively, you can preselect dependency data in the 3D view, then this option, to update multiple dependencies at once.

      Tip: Use the quick keys "dmf" to enter dependency start editing mode, or "dmt" for end editing.

  8. If required, select Delete and remove any manual dependencies you no longer need.

    Tip: You can also use the quick keys "ddt" to launch dependency deletion mode.

  9. Once dependency creation is complete, update your project using Save.
