OneThe operation
A captive coal mine supplying an integrated steel group.
Tippers, excavators and wheel loaders working the same faces.
Material moved by truck from the face to stockpile and despatch.
The problem
Haul cycles were recorded on instrumented trucks, but a trip loaded by an uninstrumented machine had no loading event, so its tonnes and the loader’s output could not be attributed.
How the work is phased
MeasureTrips without a loading event reported as a coverage gap rather than estimated.
SpecifyPayload sensing chosen per machine type.
ExpandRFID load identification across the fleet, pairing each truck with its loader at every pass.

What changes on site
Today: Loading events missing for some trips
Missing events reported per trip, with the loader
Today: Tonnes from trip count and capacity
Payload measured on fitted machines
Today: Loader output estimated
Passes and load per loader, per shift
Today: One sensing method for all machines
Method chosen per machine type
