Tutorial - Automatic Ramp


Use the Automatic Ramp option to construct underground ramps between two locations in space. The two locations are joined by an automatically created line that will preserve specified design constraints. These design constraints include the maximum absolute grade, minimum curvature radius, exclusion zones, maximum number of turns, transition grades, connection angles, and curvature constraints.

The Automatic Ramp option will test several possible solutions in a defined processing time. The resulting solutions can be ranked using a block model. Once completed, the best solution found will be presented for further refining or for manual editing. The resulting ramp can also be reserved using primitives as well as general or advanced reserves.

The dataset for this tutorial is in the AutomaticRamp.zip file. (click the link to download the dataset).

  1. Open Vulcan with the dataset from the Automatic Ramp folder.
  2. Open ugdesign.dgd.isis and load the ZONES layer.
  3. Right-click on one of the points and select Label > Point sequence to display the Label Option panel, then select All Points and click OK. The point labels are displayed.
  4. Select Underground > Development > Automatic amp to display the Automatic Ramp panel.
  5. Click Specification Definition in the menu on the left side of the panel and select ug.ros from the Ramp optimiser specification file (.ros) drop-down list.
  6. Click Apply and Run.
  7. Change the indicate mode to Snap to Points mode by clicking on the Snap to Points icon ( ) on the Digitise toolbar.
  8. Click Point 1 for the start points.
  9. Click Point 5 for the end point.
  10. Click Point 2 for the first fixed point, followed by Point 3 and Point 4.
  11. Right-click to display the Ramp Completed menu and select Retain Current.

Notice that the ramp includes all of the selected fixed points and that the ramp was lengthened to ensure that the maximum grade was not violated.
