Workflow

WorkflowThe following workflow demonstrates the steps in this tutorial. There are other ways to achieve a

similar result.


Document conventions Typographical conventions

Document conventionsTypographical conventionsSome text in this guide has special formatting to help you identify it as part of a particular element of

information. The following table describes the different text formats and their meanings.

Text format Meaning

<Bold Italic>

Text or data that varies with each input is shown in bold italic font and enclosed in angle brackets.Some examples are installation directories, dates, names, and passwords. When you substitute thetext for the variable, do not include the brackets. For example: <password> requires you tosubstitute a password in place of ‘<password>’.

ItalicA word or phrase to which the author wants to give emphasis. For example: youmust select anitem from the list to continue.

Bold

This font style indicates one of the following:

l A file name, path, or URL.

l Strongly emphasised text. For example, “It is very important to save the data […]”.

l Text that a procedure has instructed you to type.

l A menu option, tab, button, check box, list, option button, text box, or icon.

For example: Save the file as pit1.str.

Keyboard conventionsKey combination Meaning

<key>+<key>Press and hold the first key, then press the second key. For example: CTRL+Z means pressand hold the CTRL key, then press Z.

Menu conventionsWhen you click, or move the pointer over, somemenu commands, a secondary, or subordinate,

menu appears. To indicate that you should select a command on a subordinatemenu, this

documentation uses a greater than (>) sign to separate themain menu command from the

subordinatemenu command. For example, File > Project > Project Managermeans choose the File

menu, move themouse pointer over the Project command, and then select Project Manager on the

subordinatemenu.

Concepts HaulRoad Segments

Concepts

OverviewThe concepts presented in this tutorial are concepts from themining domain or concepts specific to

Minex.

Minex concepts

Haul Road SegmentsHaul road segments are physical locations, with coordinates. They are a way to travel from one point

to another. A haul road segment is represented by a string that has a Data Type of Road Design, and

a String Type of CentLine.

Haul RoadsA haul road is a physical path, from a pit to a dump. Haul roads aremade of one or more haul road

segments, and have coordinates.

RoutesA route is a virtual link, that you can use to move from one location to another. A route can contain

one or more haul roads.


Concepts Haul road speed limits

Route containing one haul road

Route containing more than one haul road

Haul road speed limitsYou can define the speed limits for haul roads when you create the haul road segments. For each

haul road segment and intersection, Minex uses the speed limit that applies to the specific situation.

For example, when the vehicle is travelling from the pit to the dump on along haul road segment 1,

Minex uses:


Concepts Haul road speed limits

l the Entry Speed Outbound for the start of the segment

l the Speed Limit Outbound for the length of the segment

l the Exit Speed Outbound for the end of the segment


Setup for this tutorial Activity: Install the data set

Setup for this tutorial

Tutorial dataWhen you install Minex and accept the default installation settings, the tutorial data is installed on

your machine. If you choose not to install the tutorial data sets when installing Minex, you can install

them separately.

Activity: Install the data set

1. Double-click theMinexInstallation.msi file on the installation CD.2. At theWelcomemessage, click Next.3. SelectModify, and click Next.

Minex displays the Custom Setup options.

4. Click the icon next to the Tutorial Data Sets option and select This feature will be

Windows XP C:\Documents and Settings\All Users\GEOVIA\GEOVIAMinex\6x\shared\tutorialData\Datasets\Dump_Scheduling\

Note: If you changed the default settings when you installed Minex, the files may be in a different

location.

Activity: Back up the data setIt is a good idea to keep a backup copy of the data in case you want to restart the tutorial with a

fresh set of data later.

1. Start Windows Explorer.2. Browse to the data set.3. Right-click theDump_Scheduling folder, and choose Send To > Compressed (zipped)

folder.4. In Windows Explorer, make a new folder for backups, for example C:\minexBackups, and

copy the zip file to that folder.


Setup for this tutorial Activity: Create aMinexproject

Create a Minex projectTo make it easy to work with your data, you will create a Minex project and set the working directory

to the location of the tutorial data (Dump_Scheduling).

Activity: Create a Minex project

1. Start Minex.2. Select File > Project > Project Manager.3. Click New.4. In the Project Name field, typeDumpSchedulingTutorial.5. Browse to theDump_Scheduling folder.

Tip: When you are browsing to this folder you can click the Jump to My Documentsicon to select a folder that is close to the folder of the data set.

When creating a new project, you have the option of using the 'file collection' setting. You

choose a file collection setting when you want to have the data set organised into

subfolders with meaningful names rather than a single folder. For this tutorial you will not

organise the data.

6. Click Finish.


Setup for this tutorial Activity: Create aMinexproject

The project is set up and theMinex Explorer displays theDump_Scheduling folder and

subfolders.

Note: If you use Hub to manage your files, Hub status icons are displayed beside the

files in theMinex Explorer. For this tutorial, Hub status icons are not shown. For more

information on Hub, refer to the Help, or the Hub training guide available with theMinex

tutorials.

Tip: In theMinex Explorer you can select the top level folder, which is Dump_Scheduling for this project, look at the Properties pane, and see the full path of the

project. This is useful if you forget, or want to verify, where the data is.


Create a dump schedule database Activity: Create a dump schedule database

Create a dump schedule databaseYou create a dump schedule database (.accdb) so you can save the dump schedules you create.

Activity: Create a dump schedule databaseTo create a dump schedule database (.accdb):

1. Choose File > New.

TheNew Wizard opens.

2. Select theDumpDB.accdb template, and click Next.


Create a dump schedule database Activity: Create a dump schedule database

3. In theName field, typeDump.

Note: If you do not provide a name for the dump schedule database, the default name

DumpDB is used.4. Click Finish.

The dump schedule database (.accdb) is created and is visible in theMinex Explorer.

The tick icon beside the database indicates that it is open.


Create a scenario Activity: Create a scenario

Create a scenarioYou create a scenario to hold all of the information about the relationships between pits and dumps.

You configure your scenario in the Scenario Manager, which is used to manage dump scheduling

data. The Scenario Manager can contain one or more scenarios. Each scenario contains routes

between pits and dumps, and the constraints for each dump, including where and when material can

be dumped, and how the dump is filled. You can also use the Scenario Manager to define truck and

loader parameters for your fleet.

Note: Before you create a scenario, all the pits and dumps you want to use in the scenario must

exist.

Activity: Create a scenarioTo create a scenario:

1. In theMinex Explorer, right-click the reservesDB PIT_DUMP.dbr, and chooseOpen.

A tick icon appears beside the database, indicating that it is open.2. ChooseOP Dump Schedule > Scenario Manager.

The Scenario Manager appears.3. Click the Load Scenario tab.4. In the Load Scenario File section, click Create New.

The Save... dialog opens.5. In the File name field, type dumpScenario, and click Save.

You can now create a scenario.6. In theMake Scenario Current section, click Create New.

A new scenario is visible in the Scenario panel.


Create a scenario Activity: Define routes

7. In the Scenario panel, select the scenario and clickMake Current.

The tick icon beside the scenario indicates that it is current. The Status panel at the bot-

tom of the Scenario Manager lists the current scenario.8. At the bottom of the Scenario Manager, click Save.

You can now define the links, or routes, between the pits and dumps in your scenario.

Define routes between pits and dumpsYou define routes between pits and dumps to specify wherematerial from each pit can be dumped.

First you will add the pits and dumps to the scenario, and then you will define the routes.

Activity: Define routesTo add pits and dumps to a scenario:



1. In the Scenario Manager, click theDefinition tab.2. Add a pit to the scenario:

a. In the Palette to the right, click the Pit icon , and drag it into theDefin-ition panel in the centre.

The Select Pit/Dump dialog appears.

b. From the Pit/Dump number list, select 91.

Note: The pits available in the list are those in the current reservesDB.c. Click Ok.

Pit 91 is added to theDefinition panel.3. Add dumps to the scenario:

a. In the Palette, click theDump icon , and drag it into theDefinition panelin the centre.

The Select Pit/Dump dialog appears.

b. From the Pit/Dump number list, select 902.

Note: The dumps available in the list are those in the current reservesDB.c. Click Ok.

Dump 902 is added to theDefinition panel.

Note: The Status panel shows an error for dump 902: The sequence file of

this dump is not set. You will set the sequence file later in the process.



d. Repeat the process to add Dump 903.

Note: The Status panel shows an error for dump 903: The sequence file of

this dump is not set. You will set the sequence file later in the process.4. Add an infinite dump to the scenario:

Note: You do not necessarily need to add an infinite dump at this stage. You could

begin scheduling without an infinite dump, however, you are adding the infinite dump

here to accommodate overflow from the other dumps. An infinite dump has no geo-

metry, so cannot be displayed. However, it is a location wherematerial may be dumped,

and can be reported on. When you create an infinite dump, it is created in the

reservesDB.

a. In the Palette, click the Infinite Dump icon , and drag it into theDefin-ition panel in the centre.

The Select/Add New Infinite Dump dialog appears.

b. In theNew Dump No field, type 905.c. Click Ok.

The infinite dump is added to the scenario, and to the reservesDB.5. Link the pit and dumps with routes:

a. In the Palette tab, click the Route icon .The Route icon is highlighted.

b. In theDefinition panel, click pit 91, and then dump 902.

You have created a route between pit 91 and dump 902.c. Repeat the process to create routes between pit 91 and dump 903 and pit 91

and dump 905.



Your finished definition should resemble the following:

6. On the bottom of the Scenario Manager, click Save.


Create a dump sequence Activity: Create a dump sequence

Create a dump sequenceYou can use theDump Sequence Generator to create a practical sequence for dumping material in a

dump. You can specify rules for dumping material, and you can use the Replay tab to preview the

dump sequence in Graphics.

Activity: Create a dump sequenceTo create a dump sequence:

1. ChooseOP Dump Schedule > Initialize > Dump Sequence Generator.

TheDump Sequence Generator form appears.

2. In theDump Display section, from theDump Pit list, select 902.3. In the File Selection section, in the File field, typeDump902_sequence.4. In the Sequence Generator section of the Automatic Sequence Generator tab, click Auto-

Generator.5. The Sequence Generator table is populated.6. Click Save File.

The sequence file is saved, and is visible in theMinex Explorer.


Create a dump sequence Activity: Configure dumps

7. Repeat the process to create a dump sequence file, called Dump903_sequence, for dump

903.

Tip: Ensure that the Sequence Generator table shows three benches for dump 903.Note: You do not need to create a dump sequence for dump 905. Dump 905 is an infin-

ite dump, and has no geometry, and therefore no strips, blocks, or layers to fill in any par-

ticular order.8. Close theDump Sequence Generator form.

Configure the dumps in a scenarioYou can specify the parameters of dumps to control when and wherematerial can be placed in

dumps. You can:

l specify when dumps are available

l choose which sequence file is used for each dump

l define any lag associated with dumping material near blocks that have not been com-

pletely mined

For this guide, you will only use a sequence file.

Activity: Configure dumpsTo configure dumps:

1. In the Scenario Manager, click theDumps tab.2. Within theDumps tab, click the Sequence tab.3. In theDump Selection panel, select Dump 902.

4. Use the ellipsis button to locate dump902_sequence.DPSQ, and click Select.5. In the Sequence tab, click Load.

The error message for Dump 902 is removed from the Status panel.6. Repeat steps 3 to 5 to load the sequence file dump903_sequence.DPSQ for dump 903.

Note: You do not need to load a sequence file for the infinite dump 905.7. To save the changes to the scenario file, on the Scenario Manager click Save.

Rank the dumps associated with each pitYou can rank the dumps associated with each pit. Minex uses the ranking to determine the order in

which dumps are filled with waste from a pit. The dump with the highest ranking (for example 1) is

filled completely, then the dump with the next highest ranking (for example 2). All dumps with the

same ranking are filled at the same time based on the sequence of each dump.

Note: Infinite dumps do not contain blocks, so the dump cannot be filled completely. If you

indicate that an infinite dump should be filled before normal dumps, material is dumped only in the

infinite dump. Because the infinite dump is never filled completely, Minex cannot start to dump

material in the next dump. If the infinite dump has a higher priority than the other dumps, the other

dumps will never be filled.


Create a dump sequence Activity: Rankdumps

Activity: Rank dumpsTo rank dumps:

1. In the Scenario Manager, click the Pits tab.

The pit in the current scenario, pit 91, is visible in the Pit Selection panel.2. Select Pit 91.

The dumps associated with pit 91 are displayed in theDump table.

3. Click the Ranking field for dump 905, and change the value to 2.

With these rankings, dump 902 and dump 903 are filled at the same time. When both 902

and 903 are filled, material can be deposited in the infinite dump, 905.4. Click Save.5. Close the Scenario Manager.


Create and run a dump schedule Activity: Open prerequisites

Create and run a dump scheduleAfter you have created and defined an appropriate scenario, you can create a dump schedule, and

then run the schedule.

You can:

l create a new open pit schedule and a new dump schedule and schedule both together

l replay an existing open pit schedule and watch the dump fill as the pit is mined


Open prerequisitesThere are several prerequisites you will need while working with your dump schedule, you will open

them now.

Activity: Open prerequisitesTo open the prerequisites:

1. In theMinex Explorer, open the following files:

l the calendar file 10x2x7.BCAL

Create haul roads Activity: Create haul road segments between pit 91 and dump 902

Create haul roadsIn theDefinition tab of the Scenario Manager, you created routes to specify wherematerial from

each pit could be dumped. Now, you will create haul roads to define the physical path, from a pit to a

dump. Haul roads aremade of one or more haul road segments.

Activity: Create haul road segments between pit 91 and dump 902To create haul road segments:

1. Clear Graphics.2. Click the 3D Design tab.3. Make sure the geometry file PIT_DUMP_HAULROADS.GM3 is open.4. Press Ctrl + D, to open theGeometry Display form.5. Fill in the form as shown.

Because you are creating haul road segments between pit 91 and dump 902, you only

need to display the geometry for that pit and that dump.6. Click Ok.

Pit 91 and dump 902 are displayed in Graphics.



Next, you will display the topography.7. In theMinex Explorer, expandMerged.grd.8. Select TOPS.grd, right-click, and chooseDisplay and Open.

The grid is displayed in Graphics.



9. Choose String > Create.

The String - Create form appears.10. Fill in the form as shown.

Each haul road segmentmust have a unique combination ofGroup,Map, Ident, and



Class.

It is strongly recommended that you use the following naming convention for haul road

segments:Field ValueGroup The number of the pit.

Map The number of the dump.

IdentHx_SyWhere x is the number of the haul road, and y is the number of the segment within that haulroad.

11. Click Ok.

The default Digitisemode is Snap to Solid, so when you digitise the haul road, it adheres

to the topography represented by the TOPS grid.12. Digitise a haul road segment from Pit 90 towards Dump 902, similar to the image below.

Tip: When you have finished digitising the segment, right-click in Graphics, and chooseAccept.

13. Reopen the String-Create form.



14. Fill in the form as shown.

Tip: If you create the second segment using a differentWeight than the previous seg-ment, it is easier to tell them apart.

15. Click Ok.16. From theDigitise list, select Snap to Point.

The segments in a haul road cannot have gaps between them, so you need to ensure the

new segment connects to the previous segment.17. When Minex indicates the end of the previous segment with a square, digitise the start of

the new segment.

18. From theDigitise list, select Snap to Solid.

Now the rest of the haul road segment will adhere to the topography.

Now you can calculate truck cycle times.


Calculate truck cycle times Activity: Calculate truck cycle times

Calculate truck cycle timesYou can calculate the amount of time it takes for a truck to carry a load of waste from a pit to a

dump, and then return to the pit. You can calculate truck cycle times for all truck-loader-haul road

combinations for all routes in a selected schedule.

The calculated truck cycle time includes:

l Spot Time at Loader: The time the truck takes to park at the loader.

l Load Time: The time it takes for the loader to fill the truck with waste.

l Travel Time: The time the full or empty truck spends travelling on haul roads and

ramps.

l Unload Time: The time it takes the truck to unload at the dump.

l Wait Time: The time the truck spends waiting. For example, waiting to be loaded, wait-

ing to enter the dump.

Tip: For more information on calculating truck cycle times, refer to the Help.

Activity: Calculate truck cycle timesTo calculate truck cycle times:

1. Make sure the following files are open:

l PIT_DUMP_HAULROADS.GM3

l PIT_DUMP.dbr

l Dump.accdb

l DumpEquip.accdb2. ChooseOP Dump Schedule > Build > Calculate Truck Cycle Time.

The Calculate Truck Cycle Time form appears.


Calculate truck cycle times Activity: Calculate truck cycle times

3. From theDump Schedule list, select 2.4. In theUse simple road length/speed algorithm section, make sure theNever option is

selected.

You can choose to use the simple road length/speed algorithm instead of the default com-

plex algorithm. Both algorithms use the spot time at loader, load time, travel time,

unload time, and wait time. However, unlike the complex algorithm, the simple algorithm

does not use truck performance or road parameter data when calculating travel time. The

simple algorithm can be useful if you do not have truck performance data.

You can choose to use the simple algorithm:

l Never: Minex uses the complex algorithm to calculate all truck cycle times.

Any anomalies are reported to theOutput Window.

Note: Minex identifies anomalies when you have not provided truck per-

formance data, or the truck is incapable of performing the work.

l On calculation anomaly: Minex uses the complex algorithm to calculate

truck cycle times. If a truck cycle time cannot be computed, Minex recal-

culates that truck cycle time using the simple road length/speed algorithm.

The anomaly is reported in theOutput Window as Corrected.

l Always: Minex uses the simple road length/speed algorithm to calculate all

truck cycle times.5. Click Populate From Schedule.

The Pit/Dump table is populated. You can adjust the Traction and Resistance values if

necessary. For this activity, leave the default values in place.6. Click Ok.

Minex calculates the truck cycle times for the selected schedule.

There should be no anomalies when you calculate the truck cycle times in this tutorial.

However, when an anomaly does exist, a message appears in theOutput Window. For

example, Travel time compute anomaly - truck DPR1_HITACHI exceeds speed limit

along Haul road HR1_HR3 for Pit 904, Bench 1, Strip 5, Block 4.

Tip: You could investigate the error by checking:

l the equipment parameters on the Fleet tab of the Scenario Manager

l the haul road segment gradient and properties

l themax gradient of the ramp
