Setup

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.

To install the Hub, see Installation and Setup.
To run the Hub, double click the shortcut icon on your desktop, or search for "Alastri Hub" via the Start menu.

Alastri Hub - license manager and app launcher

Once in the Hub,

Click the Haul Infinity option
Select the latest public version
Click Start to launch the software

Project Setup

Haul Infinity has a series of setup steps that must be followed.

Settings

The first step in creating a project is to review the project settings.

Select what settings to use when starting a new project.

Units

Select the units of measurement which match your site coordinate system and local standards.

Select your preferred units of measurement.

Bench Settings

Bench Settings control the travel parameters between a block and the network.

Configure the travel parameters from a block to the road network

The connection between a block and the road network is known as an "autojoin". These parameters describe how a truck travels along an autojoin.

Bench settings allow tiered speed limits as a truck exits the bench

Bench Setting	Effect
Rolling Resistance	Rolling resistance used for on bench travel.
Active Work Area Speed Limit	Speed limit as the truck pulls away from the digger.
Active Work Area Radius	Distance to maintain the Active Work Area speed limit.
Access Road Speed Limit	Speed limit as the truck exits the Active Work Area.
Access Road Length	Distance to maintain the Access Road speed limit.
Main Road Speed Limit	Speed limit between the Access Road and the Network.
Auto Join Distance	Ramps are only detected within this distance of the bench.
Disable Bench Pathfinding	Disables pathfinding around voids. Trucks travel as the crow flies.
Max Block Pathfinding Grade (%)	Forces the pathfinding to honour a maximum rise/run gradient.

Other Settings

Take a glance over the remaining settings to ensure you are happy with the defaults.

Acceleration
Loaded/Unloaded	Maximum "kilometers per hour per second" that a reasonable operator applies to the truck.
Traction
Coefficient of Traction	Used to calculate the maximum force that can be applied to the road without skidding.
Braking Reliance on Traction	How close a reasonable operator will come to skidding before easing off the brakes.
Retarder
Use Retarder Speed Limit	Stops trucks from exceeding their OEM retard curve.
Max Use of Retarder	How heavily a reasonable operator applies the brakes.
Calculation Precision
Accuracy	Only to be changed by Alastri staff. Controls the number of iterations in numerical integration.
Zero Acceleration Tolerance	Only to be changed by Alastri staff. Controls rounding in acceleration calculations.
Transfer Speeds
Entrance Speed Unloaded	Maximum unloaded entry speed to the network from the ramp (other speed limits also apply).
Entrance Speed Loaded	Maximum loaded entry speed to the network from the ramp (other speed limits also apply).
Exit Speed Unloaded	Maximum unloaded exit speed to the network from the ramp (other speed limits also apply).
Exit Speed Loaded	Maximum loaded exit speed to the network from the ramp (other speed limits also apply).
Terminal Speeds
Arrival Speed Unloaded	Final arrival speed at digger. Usually zero (could be non-zero if cruising into Spot At Loader).
Arrival Speed Loaded	Final arrival speed at dump. Usually zero (could be non-zero if cruising into Spot At Dump).
Departure Speed Unloaded	Starting departure speed from dump. Should always be zero.
Departure Speed Loaded	Starting departure speed from digger. Should always be zero.
Corners
Corner Lookahead Distance	The arc distance used to calculate the angle of deviation for cornering speeds.
Path Finding
Try Return on Same Route	Forces trucks to return the way they came, even if there is a faster alternative route.
Advanced
Various cache settings	Only to be changed by Alastri staff.

Truck Models

Truck models define the work capacity of trucks under different conditions.

Download Trucks

Navigate to the Alastri truck library and download:

Caterpillar 789C
Komatsu 730E
Hitachi EH3500

Import Trucks

Go to Trucks > Models > Add Truck > Import Trucks from Files and import the three trucks from your downloads folder.

Trucks can be imported via Add Truck > Import Trucks from Files

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.

Hold shift or control to select multiple trucks from the list.

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.

Ascent and Descent

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.

Theoretical Calculations

The sections Loader Payload Calculation, Truck Payload Calculation, Loading Calculation are used to calculate cycle times from first principles.

Historical Overrides

The section Overrides is used to calculate productivities from historical inputs.

Loading Times

Haul Infinity distinguishes between Truck Load Time and Loader Load Time.

Loader Load Time = Truck Load Time + Truck Spot Time

This distinction is important to ensuring that loader productivity calculations accurately catch the delays between each load, as well as the loading time itself.

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.
