Gantt Intro

The Gantt contains the planned Drilling, Charging, Blasting, and Mining sequences.


Gantt tab overview

Gantt items

The Gantt tab consists of the following items:

Panels Purpose

Toolbox

List of schedule actions, such as:

  1. Sequence – A sequence of blocks/blasts planned for an agent.

  2. Delay Sequence – Similar to a Sequence but delays can be added between blocks/blasts and after the Delay Sequence is complete.

    3. Note: In order to honour delays, Delay Sequences ignore Gantt priorities.

  3. Stockpile – A list of stockpiles with priorities which are allowed to be reclaimed.

  4. Follow – Assign one agent to follow another.

  5. Delay – Assign a delay to the agent.

  6. Blast – Blast window for when loaded patterns can be fired.

Timeline

Horizontal time axis above the canvas

Canvas

The workspace below the timeline

Lanes panel

Lists all the lanes for each activity and agent.

  • Select a dashboard to display from the Dashboard field drop-down, or

  • Click the gear icon to configure it as described in Calendar Dashboards.

  • Select lanes to display in the Canvas.

  • Multi-selection option is available, for this hold <CTRL> key and select lanes required.

  • Click on Root to display all.

Lanes

Schedule data aligned to the timeline

Task Bar

A bar in a sequence lane that contains a start time, an end time, as well as a series of tasks to work on in that duration.

Tracks

If two task bars overlap in time, they are separated into tracks. The higher track has priority.

Task Bar State

Colour that shows above a task bar when it is active (work is being performed). If two task bars overlap in time, only one will be active.

Task

An assignment to be drilled, charged, blasted, or mined

Properties

Information about the currently selected item, where you can:

  • change a name,

  • set start and end dates,

  • add notes,

  • assign a color to a bar,

  • review the information on duration of a selected task,

  • tick different display options.

More details about the Properties tab see Properties Panel.

How to use

Agents may be given instructions by dragging a task bar from the Toolbox and into the Gantt.

  • Each task bar has a start and end time.

  • Agents commence work at the task bar start time.

  • Agents work until either (a) all tasks are complete, or (b) the end time is reached.

  • Completed tasks are shown in the Sources lane and Destinations lane, in conventional Gantt chart format.

Blast 12 mining task is finished before the task bar end time

Overlapping tasks are resolved in top-to-bottom priority order. Agents will try to execute the top task bar, then the next down, and so on. If a new task bar starts on a higher track than the current task bar, then the agent will stop the current bar and move up to the higher track.

Note: Delay sequences will remain active until they are completed or they reach the end of the sequence bar. They do not follow the normal Gantt chart lane priorities. This is because any delay placed at the end of the sequence needs to be honoured.

Overlapping tasks are resolved in top-to-bottom priority order

What makes task bars interesting is that you can queue up a series of tasks (like dig blocks on a bench), that automatically reschedule around other delays like shutdowns or tramming.

Low priority tasks are automatically resumed after high priority tasks are complete

Shared Agents

If the Shared Agents function is enabled in the Final Configuration step (see Final Configuration), in the Gantt chart there is a new row called Other User, and in the Scenarios window on the left, there is also a new Shared Agents panel. Every time the other user runs the schedule, it will copy a snapshot of the sequences and scheduling breadcrumbs to the shared directory, which you can see in the other user row. If more than one user is scheduling, you can use the Shared Agents panel on the left to choose which one you want to view.
