TS. Trace tab

The Trace Report (Schedule tab > Trace tab) records decisions made when an Agent evaluates a source block. This provides a useful tool for users to understand why a block was mined (or not) at a particular point in time.

Exclusions

Disabled Agents

If an Agent is completely disabled from making decisions (for instance, it has no capacity), then it records nothing in the Trace Report.

If an Agent is completely missing from the Trace Report, check Calendar > Loaders > Direct Utilisation is greater than zero.

Dump Dependencies

In the case where dumps are blocked by dependencies, the Trace Report will show "No Available Destinations" with no further information.

If the Trace Report shows "No Available Destinations" with no other messages, it may be that all dumps are blocked by dependencies.

Example Usage

Resolve an instance where a pit or block is not being mined:

  1. Navigate to the Animation tab.

  2. Drag the animation slider forward to view the mining sequence.

  3. Observe that a block is not mined/drilled at the desired time.

  4. Left click to select the block.

  5. Right click and select "Show Dependencies and Traces".

  6. Check the Dependency list (top) for unsatisfied dependencies.

  7. Check the Traces list (bottom) for schedule messages.

Trace messages for R9400 in period 12

Resolve an instance where a stockpile is not being mined:

  1. Navigate to the Trace tab.

  2. Filter the Full Name column and type "Stockpiles".

  3. Select the stockpile to inspect.

  4. Read the Traces list for scheduling messages.

Trace messages for stockpile ROM1_1 in period 3

Note that stockpiles only appear in the Trace Report when scheduling in Truck Constrained mode.

If a stockpile is not reclaiming in Optimise Products mode, review the TS. Product Specifications.

Dependency

Waiting for mining block to be released by dependencies

Setup > Dependencies > review dependency settings

Dependency

Hit a proximity constraint <PROXIMITY> - so cannot choose block

Drills:

Setup > Dependencies > Drilling > Mining Standoff Distance

Diggers:

Setup > Dependencies > Between Benches > Max Agents on Block

Dependency

Blasting Delay holding up mining of block

Setup > Dependencies > Drilling > Blasting Delay

Setup > Refinements > Custom blast delay inputs (if any)

Agent

Agent cannot operate on the block

Drills:

Setup > Drills > Hole Types > review allowed hole types

Calendar > Drills > check penetration rate greater than zero

Diggers:

Calendar > Agents > check that Agent capacity is greater than zero

Calendar > Incentives > review Maximum/Minimum mining grades

Incentive

Blocked by priority incentive <PRIORITY>

Animation > Priority Incentives > review blockers in the named priority list

Destination Logic

Could not find applicable destination rule

Setup > Destination Logic > review destination logic

Constraint

Constraint <CONSTRAINT> prevented sending to <DESTINATION>

Calendar > Constraints > review constraint limit

Capacity

There is no remaining volume in destination <DESTINATION>

Setup > Waste Dumps > Capacity

Calendar > Dumps > capacity limit

Haul Infinity

Ignored destination due to no travel time available <DESTINATION>

Haul Infinity > Network > invalid cycle time

This may be due to no route available, dynamic haulage stage, and/or rimpull/retard curves on the truck

Equipment

Constraint (Equipment - Step Rule <RULE>) prevented sending to <DESTINATION>

This message indicates that trucks were exhausted in one of the fleets.

  • Setup > Step Logic > review the fleets used in this movement.

  • Setup > Fleets > see what diggers and trucks are assigned.

  • Calendar > Loaders | Trucks | Fleets > find the exhausted equipment.

This message usually results from over-assigning ROM loaders on ex-pit movement, or from exhausting the available rehandle trucks.

Equipment

Blocked due to exhaustion of available equipment

Calendar > Fleets > check number of units available in fleet
