The process of creating an Excavation Access Road is similar to that described above for a Main Haul Road. The following example focuses on the particular requirements of Excavation Access Road. The example road used is the same as that in the section above. This example assumes that a Pit Shell exists which incorporates a ramp on which the Excavation Access Road will be located.

The steps in setting up for and creating an Excavation Access Road are as follows:

•Ensure that a Surface Feature exists on the terrain which runs along the centreline of the proposed Excavation Access. The Excavation Access Road will have a vertical alignment located on the design high wall ramp for the strip being modelled. The Horizontal Alignment must run along this line so that the Access Road is correctly located.

•Ensure that the Pit Shell surface in which the design ramp exists has a distinctive Trace Colour. The Vertical Alignment for the access will be located along the level of the design ramp in the Pit Shell surface. It is important therefore that this Inner Surface has a distinctive trace colour so can clearly be identified when drawing the Vertical Alignment.

•Create a new Road and Horizontal Alignment. A new road is created and a Horizontal Alignment is placed running along the centreline of the design ramp and extending to the Main Road.

•Set Vertical Alignment. This involves editing the Seed Vertical Alignment to follow the design alignment which tracks down the high wall ramp.

 

The steps are illustrated in the following video clip:
