These exercises illustrate the best practices for using nodes in a project.

Creating Nodes at Elevation

Use this tool to create entry points for each bench in the pit or dump. 

To create nodes by elevation: 

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Centre the pit in the Network tab.

  4. Hover the mouse over the pit floor and read the RL from the status bar in the bottom left of the screen. This should be 1030.

  5. Hover the mouse over the ramp crest and read the RL from the status bar. This should be 1120.

  6. Double-click the pit ramp to select the entire length.

  7. Right click > "Create Nodes at Defined Elevations" > "As Bench Exits".

Select Range window

  1. Enter the range as <floor>,<crest>,<bench height>

  2. Press OK to continue.

This will create nodes on the pit ramp at six meters intervals between the 1030 and 1120 elevations

Node Naming

Nodes must have the unique names in HI and names must be the same as other systems in some cases.

  • If you are processing a schedule, the nodes must have the same name as the schedule sources and destinations.

  • If you are interfacing with dispatch, the nodes must have the same name as they are called in the fleet management system.

This means that nodes must be renamed from their default names.

To rename nodes in the Properties panel:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Centre the pit in the Network tab.

  4. Drag a box over the pit to select all pit nodes.

  5. Open the Properties tab below the viewport.

  6. Change the selection type to "Node".

  7. Edit node names in the Name row.

Dumping Time at Nodes

Set spot time at the crusher:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Open the Nodes panel in the bottom left of the screen.

  4. Select "Crusher" in the list.

  5. Go to the Properties panel at the bottom of the screen.

  6. Change the SpotAtDumpSeconds from 30 to 50 seconds.

Using the Nodes Panel

Organizing nodes by property:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Open the Nodes panel in the bottom left of the screen.

  4. Clear the Grouped Fields by dragging each row into the Available Fields list.

  5. To organize the Nodes by their type, drag "NodeType" from the Available Fields list into the Grouped Fields list.

  6. To organize nodes by their ramp, drag "Ramp" from the Available Fields list into the Grouped Fields list.

Creating custom properties:

  1. Go to Tools > Project Settings > Custom Properties.

  2. Press the green plus icon  to add a new property.

  3. Rename the new property to "Region" and set the default to "ExPit".

  4. Press ОК to accept.

  1. Drag a box over the pit to select all in-pit nodes.

  2. In the Properties panel change the selection the "Nodes".

  3. In the Properties panel change the "Region" to "InPit".

  4. Go to the Nodes panel and drag "Region" to the top of the Grouped Fields.
