Prerequisites

The procedure for assigning a Hybrid Road using Virtual Accesses, is similar to the procedure outlined in the previous topic for assigning Roads on Terrain. Basic procedures detailed in the previous topic are not repeated here and the knowledge of these is assumed.

Assigning Hybrid Road Systems

The two procedures differ only in the setup of Excavation and Dump accesses.

The figure below shows the Simulation Settings dialog, Roads page and the settings for Virtual Access are indicated:

Simulation Settings Dialog, Roads Page,Virtual Access Roads Settings

When using Hybrid Roads the first task is to select the first group of Subsequences, then select the Main Haul Route from the Haul Route pulldown list.

Next the Use Virtual Road radio button is first checked. The figure above shows this radio button set in the Excavation Access group. Once this radio button is checked the Use Main Haul Access Point checkbox is enabled and this box is checked. The Use Main All Access Point field is then enabled. In this field the Access point on the Main All Route, for the currently selected Subsequences is keyed in.

Next the Use Virtual Road radio button is the Set Travel Time Parameters button. Clicking this button opens dialog box allow in the Virtual Road parameters for the particular Access to be set.

Once the Main Haul Route and the Accesses are specified be assign button is clicked which completes the road assignment for the selected Subsequences.

The example pit used in the previous topic is shown below set up for a Hybrid Road system using Virtual Accesses:

Hybrid Roads Example, Main Haul and Accesses for Upper Passes.

Hybrid Roads Example, Main Haul and Accesses for Lower Passes

The following table details the waste passes, roads and access points and dumps. All coal Subsequences are mined without dumping and material reports to Material Log.

Pass	Dump	Excavation Access Point	Main Haul Road	Dump Access Road
Ate waste	South Pit St2 Low Wall top	South Pit Main Haul 50m	South Pit Main Haul	South Pit Main Haul 550m

Ate waste	Out of Pit Dump 1	South Pit Main Haul 50m	South Pit Main Haul	South Pit Main Haul 550m

Boreas waste	South Pit St2 Low Wall top	South Pit Main Haul 50m	South Pit Main Haul	South Pit Main Haul 550m

Boreas waste	Out of Pit Dump 1	South Pit Main Haul 50m	South Pit Main Haul	South Pit Main Haul 550m

Chione waste	Strip 3 low wall dump base	Main Haul Pit Floor 200 m	Main Haul Pit Floor	Main Haul Pit Floor 275 m

The figure below shows the Simulation Settings Dialog, Roads Page set up for the assignment of the Hybrid Road system for the first group of Subsequences:

The following topic, Procedure for Assigning Roads Example, includes two Road Assignment examples one four Roads on Terrain and one for a Hybrid Road assignment.
