Using the layers and blocks as a reference, in the Network tab draw in a road network upon which the truck fleet will run.
Importing Pits and Dumps
To be able to schedule the mining operation, you will need to simulate the transport network as on your mine site. To do this, you need to draw the roads connecting the pits to the waste dumps, stockpiles and other components. When you are doing this from scratch, you need a reference, such as Design Surfaces and Blocks created in Rapid Reserve, or other scheduling software.
Importing Surfaces and Designs
Importing Blocks
Drawing Roads
Draw roads to connect all imported blocks to the road network.
Connections are made when passing through the travel RL.
There are different ways you can do this:
Display the design and trace over the centerlines, or
Use the solids to have a visual feel as to where the connections (autojoins) been made.
Draw Segments tool
Press the pencil icon and left click on the surfaces to draw roads that connect the pit and dump.
The shortcut key <D> can be used to start and stop drawing.
To draw a ramp, display your pit blocks from below. This way you will immediately see how the isolated blocks become connected (painted green in viewport and marked with green tick in the Blocks panel on the left).
Note that in order to proceed to the scheduling, ALL blocks must be connected to the haulage network.
Further details on how to do this can be found in the sections HI. Blocks Exercises and HI. Assign Joins Based on Segment Names.
Show Mouse Text (from the toolbar) and when drawing networks on ramps check a tooltip and make sure the slope is not too big.
Nodes
Once your base network is done, you can add nodes of your site components, such as Stockpiles, Crushers, Entry/Exit of Benches and Lifts and WayPoints.
Adding Nodes
Creating a node is as simple as right clicking a point on the network and selecting "Promote Point to Node".
The corresponding node centroid will appear at the selected point.
Select the added node and in the Properties panel, rename it from the default "New Node" to an appropriate name according to the naming convention, ie “Stockpiles/<StockpileName>”, “Crushers/<CrusherName>”, “Dumps/<DumpName>”, etc.
Nodes must have the same unique name in all projects and documentation.
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.
Defining Sources and Destinations
Nodes are fixed load points (or dump points) that we manually connect to the network.
Typically, these represent Pit centroids, Dump centroids, Stockpiles and Crusher bins.
Node | Type | |||
---|---|---|---|---|
Bench Exit | Exit point from the pit level (bench). Useful when you have no blocks but have a pit design where you can place these exit points at each given elevation. More details see in the section HI. Node Exercises. | Source | - | |
Lift Entry | A point representing the entrance to the dump level (lift). Useful when you have no blocks but have a dump design where you can place these entry points at each given elevation. Use these to add reference point dumps, for example when dump designs are not available for the overflow dumping locations. More details see in the section HI. Node Exercises. | - | Destination | |
Stockpile | Material storage/rehandle point. Stockpile nodes are the only ones that can act both as a Destination (to move material from the pit) and as a Source (from where the material will be sent for further processing (Crusher) or dumping) | Source | Destination | |
Crusher | A node representing a material transformation/crushing point. | - | Destination | |
Waypoint | Waypoints are a way of breaking a long haul into a series of smaller hauls. This is useful for instances where we are interested in the time and distance spent in a particular area, such as in-pit vs. ex-pit haulage. More details see in the section HI. Waypoints. | There are neither a Source nor a Destination |
