TS. On Bench


Overview

Setting up On Bench dependencies allows the user to set dependencies between blocks on a bench/lift (mining direction along the bench). There are options to use automatic dependencies, manually created dependencies, or a combination of the two.

Example ramp point (green) marking the drop-in point on the 750 bench for Reserves planning and Example dependencies arrows (pink) marking the dumping direction on the 820 lift for Dumps planning

Auto Rule Type

Every bench in the project has an Auto Rule Type which determines automatic dependency creation. The following options are available to choose from every tree level dropdown.

Overview

Type

Description

Overview

Type

Description

 

 

None

No automatic dependencies will be created; the blocks may be mined in any order.

It is not recommended to use “None” dependencies type in ATS because without a clear sequence, the optimization will have to handle a multitude of possible scenarios, which will slow down the running time of the schedule.

Bearing

Dependencies will be created pointing the opposite of direction specified, with more than one block available at once. More details see in the section Bearing Rule below.

Bearing Strict

Dependencies will be assigned such that the blocks will be released to honour the direction specified, while only one block will be available at once. More details see in the section Bearing Rule below.

Branching

Dependencies will be created branching out from the start point(s) created by the user, while more than one block will be available at once. Both "AND" and "OR" dependency types are supported (see below).

Branching Strict

Dependencies will be assigned such that only one block is available at once and will be extracted in order of shortest distance from the starting point.

Blasts

Same as "Branching", but the start points include any blocks marked as ramp shots, and dependencies for trim shots are automatically created. Both "AND" and "OR" dependency types are supported (see below).

Blasts Strict

Same as "Blasts", but only one block is available at any one time.

Previous

Uses the dependencies assigned on the flitch above or lift below.

"AND" and "OR" dependencies types

Mining direction and “AND” and “OR” dependencies are shown by pink and blue arrows. See the table below for examples of their use.

 

«AND»

«OR»

 

«AND»

«OR»

View

Shown in pink.

Shown in blue.

Logical Function

Returns TRUE if all of the conditions evaluate to TRUE.

Returns TRUE if any condition evaluates to TRUE.

Explanation

Defines "AND" type dependencies, which means that the block pointed by the arrow will be processed after the block from where the arrow comes (the first arrow AND the second arrow) has been mined.

Define "OR" dependencies, which means that the block pointed by the arrow will be processed after either the first block from where the arrow comes OR the second block has been mined.

Example 1

 

Example 2

Selected and highlighted in yellow Blast 3008 will only be mined after blocks 36 AND 106 have been mined.

Mining on the selected and highlighted in yellow Blast 109 can begin after mining any of the blocks pointing to it with blue arrows (114 OR 107 OR 105 OR 106).

Switching the Dependency Type

  1. Select the applicable dependency type for the record from the dropdown list on the left.

  2. Use the Dependency Type button (the last one in the toolbar).

Navigating and working with dependencies

The basic principles and guidelines for working with dependencies are summarized in the table below.

Description

Tool

Drawing Dependencies

Press the Draw Dependencies icon to drag manual dependencies between blocks.

  • Drag and drop dependency arrows between blocks.

 

 

Dependencies can also be created by clicking the successor, clicking all predecessors, and then clicking back on the successor to finish. 

Select a block to start drawing - it will be shown in yellow.

To continue the dependency from the last block, click the source block so that the block to continue the dependency is highlighted in yellow.

Use the <ESC> key to cancel the last step.

Changing the Dependency Arrow Size

Use the horizontal arrow size slider to customise size of dependencies.

 

Switching the Dependency Type

To toggle between "AND" and "OR" types when drawing a dependency, press (and hold to keep your selection) the <CTRL> key.

Deleting Manual Dependencies

To delete manual dependency arrow:

  1. Click on the dependency arrow (will be shown in yellow after selection).

  2. Click the the red cross icon.

 

 

 

Clearing Manual Dependencies.

To clear manual dependencies:

  1. Right click on the tree level.

  2. Select “Clear Manual Dependencies“ from the dropdown.

 

Time Delay Setting

You can apply a time delay on manually drawn dependencies, for example, to specify that you can’t mine a trim shot until a week after the production one has been completed.

The remaining duration of the delay can be queried by launching the “Dependencies” dialog of the dependant block in the Animation tab.

Resetting currently selected rule

You can reset currently selected rule by pressing the red stop button. Note that this action will reset manual dependencies as well. Press YES in Reset Rule window if you want to proceed.

Clearing Automatic Dependencies

Automatic dependencies can be removed by selecting the block(s) and pressing the Remove Auto Dependencies button. Excluded from AutoDependencies blocks will appear shaded dark grey (as per the Legend).

You may need to use this tool for combining Automatic and Manual dependencies, if there is a particular section on the bench which you want to do manually (for example, if there is a bore in place there) to define a difference sequence to operate on.

To do this, clear the group of automatic dependencies and use the drawing tool to set the manual ones in the required sequence.

Restoring Automatic Dependencies

Automatic dependencies can be restored by selecting the block(s) and pressing the Restore Auto Dependencies button.

 

Restoring automatic dependencies by mine/pit/stage

To restore Automatic dependencies:

  1. Right click on the tree level.

  2. Select “Clear Removal from Automatic Dependencies“ from the dropdown.

 

Starting Point

If you are using Auto Blasts Shapes tools in the Designer tab in Rapid Reserver and you define Ramp and Trim blasts types, on bench dependencies will be set automatically for you in ATS.

Between the Production shots dependencies are not set automatically, so when there is no clear ramp, they need to be defined through a Starting point.

To help visualizing ramp or trim shots when placing Starting points, select "Misc_blockType" shading from the Reserves Shading dropdown (similarly for dumps). For an explanation of the color coding, see the Legend in the bottom right.

Define missing Starting points for all benches without clearly identified ramps. For some benches, you may need to set multiple Starting points.

For instructions on how to work with Starting points, see the table below.

Placing a Starting point

Select the Drawing Starting Point icon from the top toolbar (the last one in the row) and click the blast you want to put it on. The auto dependency arrows will automatically target that point.

 

Deleting a Starting point

To delete, select the defined Starting point (it will be shown in yellow) and click the red cross icon.

Placing multiple Starting points

If a bench is divided into two or more parts, you need to set a Starting point for each of them.

You can also set multiple Starting points for benches with multiple ramps.

Clearing all Starting points

To clear all Starting points from the bench, select the record from the tree structure on the left, right-click on it and select the "Clear All Starter Points / Lines" option.

Replacing Starting point auto tool

When you have a ramp shot defined in the Designer tab of Rapid Reserver, you can use the Auto Starting point tool. It will try to guess where the starting point is based on the currently loaded Haul Infinity Model.

Error message

Circular Dependencies

“The bench <(OpenPit/Mine/Pit1/Stage1/800)> is set to use the Blasts rule, but no ramp blocks or starting points were found.”

You will not be able to proceed with the setup without at least one Starting point set on benches with "Blasts" and "Branching" type dependencies.

If there are no distinct ramp or trim blasts, the Starting point(s) must be set at the bench access location.

Bearing rule

When selecting options "Bearing" or "Bearing Strict" from the tree level element dropdown in the toolbar above viewport two new commands will appear.

Example of setting direction on a Dump lift

  1. Expand the tree hierarchy to the required record.

  2. Double click the Name column to center the data in the viewport.

  3. In the Auto Rule Type column select "Bearing" option from the dropdown.
