The Trace Report 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 > Direction 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.

Navigate to the Animation tab.
Drag the animation slider forward to view the mining sequence.
Observe that a block is not mined/drilled at the desired time.
Left click to select the block.
Right click and select "Dependencies and Traces".
Check the Dependency list (top) for unsatisfied dependencies.
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:

Navigate to the Trace tab.
Filter the 'Full Name' field and type 'Stockpiles'.
Select the stockpile to inspect.
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 Optimised Products mode, review the ATS Product Specifications.

Schedule Messages

Actions

Message	Notes
Block created, and added to ASL.	Dependencies are satisfied; block is available.
Block loaded into ASL at the start of the period.	Dependencies are satisfied; block is available.
Selected block (it was ranked #1)	Block ranking based on incentives.
Removed <AMOUNT> quantity from block.	Block was mined/drilled.
Agent cannot fully complete block, as it is near its production limit.	Block was only partially mined/drilled.
There is no remaining volume in the block.	Specific parcel is completely mined/drilled.
Block is completed, and removed from ASL.	All parcels are completely mined/drilled.

Summaries

Message	Notes
No available destinations for block.	This is a summary message. Read up the list to see the actual issues.
Waiting for mining block to be released.	This is a summary message. Read up the list to see the actual issues.
Unable to completely extract block.	This is a summary message. Read up the list to see the actual issues.

Interruptions

Type	Message	Next Steps
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 Agent capacity 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 > Dumps > dump 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.
