This tutorial has been written so that users learn how to use TALPAC. The intention isthat by following the series of workshops set out in this booklet, you will be able to use

TALPAC, and have an appreciation as to the functionality of the program.

Each of the workshops sets out a number of key TALPAC concepts, what actually needsto be completed for each workshop and what the results should be at various points. As

well, there are questions that should be answered for each workshop. Some of thesequestions are qualitative, so no numerical answer has been provided. The phrases listed asconcepts in each workshop can all be found in the on-line help.

In the answers chapter of this booklet there are some answers to specific questions, andscreen captures at certain points of the process which will enable you to check yourprogress. Often these screen captures contain the numeric answer.

This tutorial does not cover every feature of TALPAC. However upon completion of thistutorial the user will have the skills required to successfully use TALPAC, and to self-learnthe TALPAC facilities not covered here.

Firstly it is recommended that you read through an entire workshop before starting it.

TALPACmay be used to analyse the performance of existing fleets of equipment or toinvestigate the application of new equipment fleets in earthmoving and mining operations.In either case, the performance of a single fleet may be examined, or a comparison made oftwo or more different fleets. TypicalTALPACapplications are listed below.

Calculation of truck travel timeto allow a comparative analysis of haul routealternatives.

Estimation of fleet productivitiesfor use in long and short term planning studies.

Estimation and comparison of productivitiesusing various loadingmethodologies to determine the optimum loading technique or loading unit bucketsize.

Sensitivityanalysis in road design criteria to assess the relative importance of roadmaintenance.


4/52



Calculation of tyre TKPH or TMPH ratings for use in tyre selection.

Estimation of fuel usage.

Determination (using discounted cash flow methods) of haulage contract costsandpricing.

Truck fleet size optimisationto quantify the effect of over and under trucking.

Incremental analyses, in which simulations can be automatically run for a rangeof haulage segment lengths and the results used to generate productivity curves.

Equipment loading analysisto optimise loader bucket size, truck capacity andnumber of passes.

Collation of resultsfrom calculations to examine the relationship betweenvariables in the calculation, eg. haul distance versus productivity, haul distanceversus truck fleet size.

A contractor has been invited to submit a tender for the removal of waste from an open-cut mine, at 2.5 million BCM per year. The contractor utilises the following equipment:

Caterpillar 992G Front End Loaders (13.68 tonne payload); and

Komatsu HD785-5 Rear Dump Trucks (99.0 tonne payload).

In bidding for the waste removal contract, the contractor must determine how many trucks

and loaders are required to meet the production target and the cost of production. Thecontractor is also unsure whether to continue with the same equipment or upgrade tolarger equipment.

In the workshops of this tutorial we will configure the required TALPAC components sothat this analysis can be undertaken.

Key Concepts: Project, Haulage System, Template

Technical Description

This workshop is to generally discuss how TALPAC works and what the key areas of data input andout put are.

The figure below shows how a Haulage System is made up of the unique combination of nominatedtemplates. The templates are where the data is held for the Material, Roster, Loader, Truck and HaulCycle. So, if you change data in one of the templates, then really you are simulating a different haulagesystem. In this way many Haul Systems can be stored in the one project.

2 . T H E M A T E R I A L T Y P E

Key Concepts: Density, Swell, Fill Factor, Production Measurement


In this workshop, the characteristics of the material being hauled by the contractor will be entered intoa template. The characteristics of the waste are described below.

The productivity results are to be reported by volume rather than weight. Since we are working inmetric units, this will mean that productivities are expressed as bcm/op.hour, bcm/shift and bcm/year.

The insitu bank density is the density of the material while it is in the ground. This parameter is used to

convert an insitu bank volume to its equivalent weight, and vice versa.

The material swell factors are used to convert bank volumes to loose volumes in the loader bucket andthe truck tray. Note that both swell factors are based on insitu volume.

The loader bucket fill factor is dependent on both the material type and the class of loader. It is theratio of the loose volume of the material in the loader bucket to the volumetric rated capacity of theloader bucket. The volumetric rated capacity of the loader bucket may be expressed on either a struckor heaped basis.

Similarly, the loader bucket fill factor may be expressed on a struck or a heaped basis. The fill factor is

selected from a scale in the material template.

Tasks

Create a new material template for the waste that the contractor is to haul. Click in theMaterialTemplatedrop down box and then either right mouse click and chooseAddoff the menu or clickon theAddbutton on the toolbar. Call the new template Tutorial Waste.

The waste has an insitu bank density of 2.2 tonnes/cu.metre.

The swell factors for the waste the contractor is to move are as follows:

Swell Factor - Bank to Loader Bucket 1.20Swell Factor - Bank to Truck Tray 1.25

For the contractor's loader mining waste, set the loader bucket fill factor to average. This shouldequate to a factor of 0.72 on a heaped basis (0.88 on a struck basis) for a Front End Loader.


14/52



Questions

1. What is the Loose Density in the loader bucket?

2. How would you use your own site specific fill factors?

3. What else will affect the filling of the bucket

3 . T H E S H I F T R O S T E R

Key Concepts: Roster, Delay, Scheduled, Unscheduled, Operating, Non-Operating


Working and operating hours for the loader and trucks are defined in the shift roster. The weekly shiftpattern is specified, and then lost shifts per year and delays within each shift are allocated. These lostshifts and delays are divided into the following categories.

Scheduled lost shifts;

Unscheduled lost shifts;

Non-operating shift delays; and Operating shift delays;

The choice of category for a delay depends on mine site work practices. By definition, scheduled delaysare those that may be fixed in time, eg. the public holiday on 25th December. Unscheduled delays aredelays that you expect, but don't know exactly when they will occur, for example clean-up around theloader area and delays due to wet weather. Operating delays are those delays when the equipment'sengine is running. Conversely, non-operating delays are those delays when the equipment's engine isnot running.

Tasks

Set-up a roster template for the shift roster described below. Call it Tutorial Roster.

The contractor operates on two shifts per day, from Monday to Friday. In addition, there is oneover-time shift on Saturdays.

The only rostered days of the year that are not worked are Christmas Day and Good Friday.

The contractor annually allows for ten shifts lost due to industrial action and ten shifts lost as aresult of wet weather.

Each shift is ten hours long. The following delays occur within each shift:

Crib (meal) break 30 minutes operating Delays either side of crib 2 x 5 minutes operating Delay at start of shift 5 minutes non-operating Delay at end of shift 5 minutes operating Delays for blasting 5 minutes non-operating Clean-up around loader 15 minutes operating

Refuelling is carried out outside normal production hours.


16/52



Questions

1. What are the total annual working hours for the loader?

2. What are the total fleet operating shifts for the year?

4 . S E L E C T I N G A L O A D E R

Key Concepts: Loader database, Distribution, Loader methodology


The contractor wants to use Caterpillar 992G front end loaders. The characteristics of the loader havebeen determined from historical data. We need to use this data to correctly define how the loader is tobe simulated.

Tasks

Right click on the list of loaders and chooseAdd. You will now be looking at the loaders sectionof the equipment database.

Choose Caterpillarfrom the Manufacturerdrop down list. Scroll down through the list of loadersuntil you find the 992G. Click on the Selectbutton.

You will now be back in the loader template. Call this template Contract Cat 992G.

The contractor's 992 loaders have an expected mechanical availability of 90% and each loader passtakes 35 seconds. Change the loader pass time in seconds and the minutes will calculate

automatically and vice versa.


18/52



Click on the Bucket Selectionbutton. The buckets available for the 992 are shown in the dropdown list. Examine all the options available, click on theAuto Selectbutton and see what effectit has. When you have finished click on the Restore Defaultsbutton and then click on OK.

Click on the Costing Datatab. The capital cost to the contractor of a 992G loader is $1,200,000.

The contractor bases its cash flow on a 10% salvage value at the end of the loader life of 25,000hours or 5 years (whichever occurs first).

The loaders are depreciated at a rate of 15% on a straight line basis.

The operating cost consists of the following components:

Operating Labour $54.76/op.hrMaintenance Labour $19.52/op.hrLube $3.79/op.hr

Tyre Replacement $11.01/op.hr

5 . S E L E C T I N G A T R U C K

Key Concepts: Truck database, Local Characteristics


Characteristics of the haul trucks in the fleet are stored in the truck template, which is structured in asimilar way to the loader template. Our example contractor uses Komatsu HD785-5 rear dump trucks.

The characteristics of the trucks are described below.

Tasks

Right click on the list of Truck Type 1and chooseAdd. You will now be looking at the truckssection of the equipment database.

Choose Komatsufrom the Manufacturerdrop down list. Scroll down through the list of trucksuntil you find the HD785-5. Click on the Selectbutton.

You will now be back at the truck template. Call this template Contract 785-5.

The contractor's trucks are equipped with standard motors and are designed to carry themanufacturer's rated payload. The Komatsu HD785-5 trucks have an availability of 85%.


21/52



Operational studies show a spot time at the loader is 24 seconds, dump spot time is 20 secondsand a dump time of 30 seconds.

Note:changing the seconds will mean the minutes are updated automatically and vice versa.

Click on the Costing Datatab. The truck capital cost is $850,000. A 10% salvage value at theend of the truck life of 30,000 hours or 6 years is assumed. The trucks depreciate at 25% on astraight-line basis.

The operating cost consists of the following components:

Operating Labour $46.37/op.hrMaintenance Labour $18.24/op.hrLube $2.59/op.hr

Tyre Replacement $10.91/op.hr

6 . S E T T I N G - U P A H A U L C Y C L E

Key Concepts: Segment, Rolling Resistance, Speed Restrictions, Forward and ReverseSegments


To perform a simulation, TALPAC needs data regarding the haul route. This workshop describes howthis data can be converted into to a format required.

The loading segments are automatically included at the start of each new haul cycle.

Task

Click on theEdit Haul Cyclebutton to open the Haul Cyclewindow.

The drawing at the end of the workshop shows a typical haul profile on which the waste contractis based. Conditions to be expected in the mine are listed below:

within 50 metres of the shovel and dump point, the truck speed is restricted to 30 km/hr;

around corners, trucks should not exceed 30 km/hr; and

when travelling down ramps, trucks must not exceed 40 km/hr.

Change the name of Haul Cycle 1 toBase Haul Route.

Add a new haul segment by clicking row 4 of the haul cycle and then either click on theAddbutton on the toolbar or by using the right mouse menu.

Call the new haul segmentAround Loader, the distance will be 50.0 metres, the maximum speed is30 km/h and all of the other factors will use the default values.

The haul profile should be divided into the appropriate number of segments. The segments maybe of any length, but should have a constant grade, rolling resistance and load. Don't forget toinclude loading, dumping and fixed time segments in the haul cycle and take into account thespeed restrictions.

Rolling resistance is expressed as a percentage of the component of the gross vehicle weight that isnormal to the ground surface. For guidance on rolling resistance values to use, access the tablefrom the rolling resistance column, right mouse click on one of the cells in the Rolling Resistancecolumn and choose Select. We will be using the average conditions for this tutorial, so click in theaverage column of the row in the table that best describes the current haul segment.


25/52



When you have added all of the haul segments needed, add the dumping segments.

As the haul route for the return journey is the same it is possible to use the Reverse all segmentsoption. Reverse all of the segments

Questions

1. When is a new segment required?

2. How many segments are required?

3. What other methods are available for constructing a haul route in TALPAC?

4. What is the benefit of using real names for segment titles?

5. What is the relationship between final and maximum speeds for segments?

7 . P R O D U C T I O N A N A L Y S I S

Key Concepts: Calculation Type, Full Simulation, Stochastic, Excavation Target


Once the haulage system has been defined it is ready to be analysed. In assessing the productivecapacity of the system you have the choice of using the quick estimate or the full simulation. The othertypes of calculations will be discussed later. Quick estimate assumes there is no variability in the truckand loader parameters, and a deterministic analysis is performed.

Full simulation takes the variability of truck and loader parameters into account using a stochasticanalysis. Parameters that may be varied in the full simulation include loader bucket cycle time, loader

bucket payload, truck travel time, truck dumping time and truck availability.

The Excavation Target feature allows the user to specify a production target. When an excavationtarget is specified the Production Summary Report lists how many days/years that it would take tomove the specified excavation target. The value for the target is independent on the measurement basischosen in the material template.

Tasks

Clicking on the Type of Calculationlist box may access Quick Estimate. Select Quick Estimateand either press the key or click on the Calculatebutton.

Similarly, selectingFull Simulationfrom the Type of Calculation list box and by using thekey or to click on theCalculate Resultsbutton to accessFull Simulation.

View the simulation results for each option and compare the differences.

View the haul cycle details, the tyres and fuel consumption, and the cash flow screens. View thedefined travel time graphs to identify the key segments of the haul cycle.

Enter a production target of 2,500,000 bcm, run a Full Simulationand then view the results atthe bottom of the Production Summary Report.

Questions

1. Why is it useful to have different calculation types?

2. What is the vertical height difference that the load is being elevated through?

3. Why can you get different results for successive runs?

4. How long does it take to reach the production target?

Key Concepts: Incremental Analysis, Results Table


The haul profile used so far is representative of haul routes at the mid-life of the waste contract. In theearly years the pit is shallower and in the later years it is deeper. The change in RL and the length ofthe ramp out of the pit vary as follows:

Year Length of Pit Ramp

1 200 metres

2 300 metres

3 400 metres

4 500 metres

5 600 metres

The distance and elevation from the surface to the top of the waste dump do not change. In planningwe need to understand how the productivity requirements change for the life of the contract.

Also we are interested in seeing the results tabulated in a different format to the standard results.

Tasks

Based on this information, determine the productivity of the fleet for each year of the contract.

Choose the Incremental Analysisbutton.

In the Incremental Analysiswindow choose theAddbutton.

In the Incremental Item Selectionwindow choose Haul Segment Distancefrom the Itemdropdownlist.ChoosePit Rampsegment from the 4: Forward Segmentdropdown list. Choose 15: Pit Ramp(rev.)from the Reverse Segmentdropdown list.

Set the First Valueto 200 metres, the Last Valueto 600 metres and the Step Valueto 100 metres.Click on OK.


29/52



If the Incremental Analysiswindow looks like this, then click on Calculate.

Examine the information displayed in the Results Table.

Note:That the column headed Row 7: Distance: TT1represents the Pit Ramplength.

Key TALPAC Concepts: Optimisation Analysis, Marginal Economics


The optimum number of trucks in a fleet is a balance between productivity and cost. The fleet sizeoptimisation carries out a series of production analyses for a range of truck fleet sizes. The results aresummarised in a table displaying the fleet size, the fleet production and the discounted average cost.

The results can also be displayed on a graph. The optimum fleet size is that with the lowest unit cost ofproduction. The optimum fleet size will not necessarily have the highest production or provide therequired output.

Tasks

Create a copy of the Base Waste Contract haulage, hit the key and rename it Workshop 10 FleetSize.

Make a copy of the base haul cycle, and call it Workshop 10 Haul.

In Workshop 10 Haul, change the pit ramp distance to 2,000 m. Remember to change both the

forward and reverse segments of the pit ramp.

Configure the rest of this haul system to have the same loader, truck, material and rostertemplates. Make sure you save this haul system after you have selected the appropriate items.

Do a Full Simulation and note the number of trucks.

Now determine the optimum number of trucks for the contractor's fleet. Choose theOptimisationbutton.

Choose the Fleet Sizeradio button and then click on OK.


34/52



Plot a graph of the Fleet size versus the marginal cost.

Compare the optimum with the truck match determined in the full simulation in the previously inthis workshop.

Export the Results Tableby going to File|Export, click on the brows button and choose aname and location for the file. Make sure theExcel 5File (.XLS)radio button is chosen and thenclick on OK. Open up your results file in Excel and examine the data.

Questions

1. What is the marginal cost of assigning one more truck than the optimum?

2. Why are the marginal economics important, and not just the average cost?

3. What is the optimum fleet size?

Key Concepts: Haulage Systems


The contractor wishes to investigate the cost benefits of moving to larger equipment for the wasteremoval contract. A new haulage system is going to be configured for the larger equipment. Newtruck and loader templates will be created.

Tasks

Add a new Haulage System, called Workshop 11 Comparison. This will have the Tutorial roster, thetutorial waste, and the Base Haul Routefrom the Basic Waste Contracthaulage system.

Create a new template for both the truck and loader, the details of the larger equipment items inwhich the contractor is interested are as follows:

Item Shovel Truck Name Dema H 285 S Dresser 510E

With this equipment each loader pass takes 30 seconds. Also for the trucks the spot time at theloader is 30 seconds. The spot time at dump is 30 seconds and the dump time is 30 seconds.

Use the Total Operating Cost checkbox to enter the operating cost


36/52



Compare the discounted average cost for the equipment fleet above with the equipment fleet usedin the workshop 10. In determining the discounted average cost, use the optimum truck fleet sizefor each option.

Questions

1. Which equipment fleet would you recommend the contractor purchase?

2. What factors affect this decision?

Key Concepts: User Defined Equipment


The equipment database contains a large range of trucks and loaders used in surface mining operations.The data supplied in the equipment database represents standard equipment and has been verified bythe appropriate manufacturer. For equipment that is not in the database or that has been modified, theuser is able to set-up their own equipment items.

Tasks

Access the equipment database from eitherView|Equipment Databaseor the EquipmentDatabasebutton on the toolbar.

Use the Type, Manufacturerand Classdrop down list to view a truck and a loader to see thedata that is stored in the database for each equipment type.

Create a user defined equipment item by copying a standard item of equipment to a new name. Tocopy an item from the standard database to a user database go to Edit|Copy Equipment.Rename your copy of the Komatsu HD785-5 toMy Mines785-5.


38/52



Question

1. What role would User Defined equipment have at your operation?

1 2 . I M P O R T I N G A H A U L C Y C L E

Key Concepts: Importing a Haul Cycle From a Text File


In a previous workshop we have created a haul cycle by manually typing in the required details for eachsegment. In TALPAC you can also import this data directly from a text file. In turn this text file canbe automatically generated in another system, such as a design package or a fleet monitoring / dispatchsystem.

The text file import facility in TALPAC can be quite sophisticated, and in this workshop only a smallportion of the functionality will be used. For more advanced requirements please refer to the help

documentation, or contact Runge.

Tasks

In theTalpac8\Tutorialsdirectory there is a flat text file called Test XYZ Space.txt. Open thisfile with a text editor and inspect the layout. This file represents the co-ordinates of a haul route.Close the file after inspection.

In TALPAC add a new Haul System called Workshop 13 Import.

Go to File|Import Haul Cycles From a Text File.

Click on theAddbutton and create a new template called Tutorial.

Click on the Browse button and find the file Test XYZ Space.txt.

Leave the First Import Lineas 1, and also leave the Comment Character as ! Now click twiceon the Next Linebutton, so that line 3 of the file is shown in the viewer.

Set the Import Data Typeradio button to X,Y,Z co-ordinates.

Enter appropriate field numbers for the entities. This is:

X coord 2

Y coord 3

Z coord 4.

All other fields should have a 0 value. This means that you will be accepting the defaults shownfor those fields.


40/52



When complete, check the Reverse all segments setting load to Empty tick box , and thenclick on OK.

Inspect the results in TALPAC. Check that two haul cycles Baso1and Baso2have been imported.

Questions

1. Why is the new haul cycle called Baso1?

2. How can this feature be used in your situation?

3. How else can the import facility be used?

WORKSHOP 1: TALPAC Overview

1. What is in a TP7 file?

The TP7 file is the data file stored in your working directory that contains all of the data andsettings for the current project.

2. What are the 5 components of a haulage system?Material, Roster, Loader, Truck and Haul Cycle.

3. What is a TALPAC project?A TALPAC project is the collection of saved Haulage Systems that are in the same TP7 file.

4. Why would you want to print out the ALL PARAMETERS sheet?For reference and auditing. For example it is useful to print this file to have as a backup of the

important TALPAC configuration settings. This is haulage system specific.

5. What are the options available on the right click of the mouse when a template name is highlighted?

6. What types of Haul Segments can be used?

7. What is the difference between adding to a template list, and editing a template?Editing a template overwrites the data that already existed in the template. Adding a new templateto the list means that a new template is created, and so all the original templates still remain.

WORKSHOP 2: THE MATERIAL TYPE

1. What is the Loose Density in the loader bucket?1.83 t/m3(See the figure below)


45/52



2. How would you use your own site specific fill factors?Change the Global variables table.

3. What else will affect the filling of the bucket?Fragmentation, operator experience, weather conditions, visibility, bucket geometry.

WORKSHOP 3: THE SHIFT ROSTER

1. What are the total annual working hours for the loader?4099 (See the figure below)

2. What are the total fleet operating shifts for the year?464 (See the figure below)


46/52



WORKSHOP 4: SELECTING A LOADER

1. What is the total Operating cost per hour?The total operating cost for each loader is $183.34/operating hour.

2. Why can the template name be different to the database equipment name?

You may want to model variations of the same basic equipment.

3. What does the default bucket payload represent?The amount of material that is actually in the bucket, not the bucket capacity.


47/52



WORKSHOP 5: SELECTING A TRUCK

1. What is the total operating cost per hour for the truck?The total operating cost for each truck is $134.48/operating hour.

2. When would you use the different truck types in the same simulation?If you were simulating a fleet that had more than one type of truck.

WORKSHOP 6: SETTING-UP A HAUL CYCLE

1. When is a new segment required?Whenever there is a change to the conditions which control velocity. Thus gradient, rollingresistance and Speed restrictions.

2. How many segments are required?See the figure below.

3. What other methods are available for constructing a haul route in TALPAC?Importing data from a text file.

4. What is the benefit of using real names for segment titles?So the user can visualise, and hence validate, the haul cycle data.

5. What is the relationship between final and maximum speeds for segments?If a certain segment has a maximum speed, then the preceding segment should have the same speedset as the final speed for it. Otherwise the truck may enter the next segment at an excessive speed.

WORKSHOP 7: PRODUCTION ANALYSIS

1. Why is it useful to have different calculation types?Mine planning requires different scenarios and options to be investigated. This means thatdifferent functionality is required. As well this is useful to calibrate the model in Quick estimate(deterministic) mode first.

2. What is the vertical height difference that the load is being elevated through?60m.

3. Why can you get different results in successive runs?Due to the stochastic distributions used in simulation.

4. How long does it take to reach the production target?approx. 1.06 Years

WORKSHOP 8: INCREMENTAL ANALYSIS AND RESULTS TABLE

1. What is the key information?Key Information is what you need to see, and so depends on the purpose of the simulation. In this

instance, cost, time, productivity, fleet size and length of haul would be key.


49/52



2. How many variables are available for inclusion in the results table?250.

3. When should you consider purchasing another truck?

In year 3. But what else should be considered?

WORKSHOP 9: FLEET SIZE OPTIMIZATION

1. What is the marginal cost of assigning one more truck than the optimum?$2.97 / bcm.

2. Why are the marginal economics important, and not just the average cost?Average costs disguise the impact of individual truck assignment.

3. What is the optimum fleet size?The run with the lowest fleet discount cost.

WORKSHOP 10: FLEET COMPARISON

1. Which equipment fleet would you recommend the contractor purchase?The larger fleet is the pure cost choice, but is this correct?

2. What factors affect this decision?Cost of capital, changes to working hours, flexibility of contract.

WORKSHOP 11: THE EQUIPMENT DATABASE

1. What role would User Defined equipment have at your operation?You can set up the specifications for the Truck and Loader which exactly match your configuration,rather than relying on the standard data.

WORKSHOP 12: IMPORTING A HAUL CYCLE

1. Why is the new haul cycle called Baso1?Set by the variable on line 2 of the import file. Otherwise it will be imported and called the same asthe import file name.


50/52



2. How can this feature be used in your situation?Eg From the mine design package a string can be digitised which represents the haul route. Thisstring can then be exported to a text file as a series of X,Y, Z points. From there it can beimported directly into TALPAC.

3. How else can the import facility be used?To import complete Haul Systems.

WORKSHOP 13: TALPAC OPTIONS

1. When should you change the options settings?Only after consideration of what they are doing. It is also suggested that if these are changed, thenmake sure that changes are properly recorded. The ALL PARAMETRS print outs, and user

defined reports in the Results Tables are two good ways of doing this.

2. How can the project manager interact with mine planning?Can make the analysis of multiple simulations easier and more straight forward.

3. How can you tell the location of the current user database?Under View | Project Propertiesthe location and name of the current user database is shown.
