Haul Infinity allows you to design haul routes in 3D using intuitive CAD tools. View and edit your network in the 3D viewport and customize all of the critical settings which affect haulage calculations. Make extensive changes and rerun immediately so you can export to your mine scheduling software of choice.

Haul Infinity is organized into two tabs:
Setup tab - contains an ordered task list to prepare the project.
Network tab - contains 3D workspace for analyzing the transport network and its elements.

Haul Infinity calculates mine haulage from first principles using the truck specifications, loading parameters and pathfinding across a road network.
Accessing Haul Infinity
Haul Infinity is launched from the Alastri Hub, which manages all Alastri licenses and applications on your computer.
...
Once in Haul Infinity, click File > New to open a new project.
...
Setup
Haul Infinity has a series of setup steps that must be followed to create a valid project.
These steps are listed below. Read through them in the section below or navigate to the HI. Setup tab page to get full information.
Note, that you can't open Network tab until all the setup steps are completed.

Truck Models
Truck models define the work capacity of trucks under different conditions.
...
Each truck is defined by its axle weights, rimpull, retard, fuel and trolley assist curves (if applicable).
Truck Limits
Truck limits define how a truck interacts with the road network under different conditions.

 TKPH Limits For this tutorial, leave the TKPH limits at default values. Engine Loads For this tutorial, leave engine loads at default values. Cornering Limits For angles of deflection greater than ninety degrees (a right angle turn), reducing the cornering speed to 15 km/hr. Speed limits For loaded downhill gradients of -9.5% or steeper, reduce the loaded downhill speed limit to 20 km/hr. For loaded uphill gradients of 9.5% or steeper, reduce the loaded uphill speed limit to 10 km/hr. |
Materials
Material properties are used to calculate payload volumes, dry tonnes and wet tonnes for productivity calculations.
Add "Ore" with a density of 2.7
Add "Waste" with a density of 2.5
...
Loaders
Loader types define the dig rates for cycle time and trucking calculations.
Add "EX2500"
Add "R9250"
...
Parameters
The parameters table holds cycle time inputs for every combination of loader, truck, and material.
...
| Note |
|---|
If entering historical overrides, double check the source data and confirm which "Load Time" you are referencing. Make sure to override both the Loader Load Time and Truck Load Time, adding or subtracting the Truck Spot Time as applicable, |
Operating Conditions
When querying a specific haul, the operating conditions can be used to quickly toggle one or more input parameters to different values.
...
Run Setup steps
When you have completed all the Setup steps of the Setup Task list, click the blue play button to run the last step or all steps to confirm and move to the Network tab.

Network
The Network tab is the main workspace in Haul Infinity, where you can draw a 3D road network over of existing pits and topos, and interact with it to create nodes and routes for haulage.
Below listed only brief instructions for setting up a sample model. Full description of the Network tab, see here.
Import Surfaces
Road networks can be drawn directly onto survey surfaces and mine designs. Surfaces are imported through the Overlays panel (full description of this panel features see /wiki/spaces/212AD/pages/30940563).
...
Importing a surface
Go to the Network tab.
Find the Overlays panel in the right of the screen.
Press the blue plus icon to import surfaces.
Navigate to the sample data folder and import .
"clippedcontours.dtm",
"pit.dtm",
"wd1.dtm",
"wd2.dtm".
The Decimation Results dialog will appear, where you can see the triangle count and specify the decimation required (in this demo project, decimation is not required). Make the necessary changes and click OK.
...
Zooming
Press the Zoom All button 
in the /wiki/spaces/212AD/pages/30938427to center the data. The topography, pit design and dump design should now be centered in the viewport. These are the surfaces on top of which the network will lie.
Overlays panel
The Overlays panel is used to work with the displayed layers. This is a /wiki/spaces/212AD/pages/30941576 present in all Alastri applications.
...
You can show or hide any of the surfaces by clicking the eye icon
. The closed lock icon
prevents the drawing tool from snapping to that surface (drawing a pit road beneath a topo, for instance). Tick the edges icon
to toggle visibility of the underlying strings.
...
Changing surface colors
Expand out the folders in the Overlays panel (manually or using Tools button > “Expand All” option).
Open the dropdown in the far right column.
Select a new color.
Press OK.
...
| Info |
|---|
When the lock icon is closed, the draw tool will not snap to that surface. Use this setting to draw through surfaces to the data underneath. |
Draw a Network
Using our overlays as reference, we are going to draw in a road network upon which the truck fleet will run.
...
Pan: |  | or middle click and drag |
|---|---|---|
Zoom: |  | or mouse scroll |
Rotate: |  | or right click and drag |
Snap Mode
The snap mode dictates what we can connect segments to while drawing. The shortcut keys <Q>, <W>, <E> can be used to switch between the three modes.
 | Snap to points on the network |
|---|---|
 | Snap to surface model |
 | Snap to constant elevation |
Draw 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.
 | Tip 1: 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). Tip 2: Show Mouse Text (from the toolbar) and when drawing networks on ramps check a tooltip and make sure the slope is not too big.
|
Draw Assistance
These features may be used to draw roads when there is no existing design.
 | Adds a vertical offset to the drawn segments. |
|---|---|
 | Adds a gradient to the drawn segments. |
Draw+Ctrl+Left click | Open a coordinate menu for absolute and relative coordinates. |
Define 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.
Types of Nodes
...
Node | Source | Destination |
|---|---|---|
Bench Exit | Yes | - |
Lift Entry | - | Yes |
Stockpile | Yes | Yes |
Crusher | - | Yes |
Waypoint | - | - |
Promoting a Node
Creating a node is as simple as right clicking a point on the network and selecting "Promote Point to Node".
...
Creating nodes example
Find the toe of the pit ramp and promote to a "Bench Exit". The corresponding node centroid will appear at the selected point.
Find the crest of the dump ramp and promote to a "Lift Entry". The corresponding node centroid will appear at the selected point.
...
Speed Limits and Traffic Rules
Road signs can be dragged and dropped onto the network to reproduce the site road rules.
...
No Entry signs have a speed limit of zero, which prevents trucks travelling along that segment.
Set Road Rules
Drag and drop some signs onto the network to create safe intersections and appropriate speeds.
Select some segments > Right click > "Set Speed Limits on Selected Segments".
...
Select some points > Right click > "Set Final Speed on Selected Points".
...
Remove Road Rules
Stop signs and slow points can be removed from segments via the right click menu.
...
| Info |
|---|
Segments have forward and backward speed properties. Enable them in Tools > Project Settings > General > Segment Direction Indicator. |
Query a Haul
In order to make cycle time calculations, Haul Infinity needs to know the material type, loader and truck type.
...
Hauls can be reactivated by selecting them from the History menu in the Route Selection panel.
Animations
Haulage animations can be turned on or off from the animations button 
. Animations can slow down some calculations times. If you are using an older computer, turning animations off may help conserve performance.
