What this project is
Mining machines work hard and fail expensively. A haul truck that breaks down mid-circuit stops production; a loader with a worn component risks a bigger failure if the component is not changed in time. A maintenance system holds the plan for every machine: scheduled servicing by hours or calendar, component life tracking for engines, transmissions and tyres, and breakdown jobs raised from operator reports and inspections. The plan keeps machines available and failures predictable, rather than discovered at the worst moment.
Component life is the key idea. Major components have expected lives in operating hours, and the system tracks hours against those lives, so a component approaching its limit is planned for change during a scheduled stop, not after it fails in the pit. That planning needs accurate hour data and honest component histories: a component moved between machines carries its history with it, or the life calculation is meaningless.
Core features
- Machine registers with service history, hour meters and component histories
- Planned maintenance scheduling by operating hours, calendar or condition
- Component life tracking with change planning before expected failure
- Defect reporting from operators, triaged into jobs with priority and parts needs
- Workshop planning with bay, staff and parts availability
- Availability and downtime reporting by machine, fleet and cause
How it is built
- Record every machine, its components and their histories first, because the plan depends on that history
- Build planned scheduling and defect triage, then workshop planning
- Add component life tracking, starting with the components whose failure costs most
- Connect operator defect reports so a fault found in the pit reaches the workshop the same shift
- Pilot on one fleet type, comparing planned versus unplanned downtime before wider rollout
Technology considerations
Hour meter data must be reliable. If hours are estimated or entered late, component life calculations drift, and the system plans changes either too early, wasting component life, or too late, after failure. Automated hour capture from machine systems helps, but manual entry with checks is workable if it is disciplined. Parts availability is the other constraint: a planned change that lacks parts becomes an unplanned stop, so the system should check parts before scheduling work, not after the machine is already in the workshop.
Workshop capacity needs the same honesty. A plan that assumes every bay and technician is free will fail. The system should model shifts, skills and bay occupancy, and show why a job cannot be fitted in, so the planner can choose: defer the job, move another job, or accept the downtime with eyes open.
For the first version, track one fleet type, such as haul trucks, with service schedules, defect reports and component lives for the components that fail most expensively. Maintenance planners judge the system on whether the next service due list matches what the workshop actually needs to do. A system that does that for haul trucks, with parts checked before scheduling, proves the approach before it is widened to loaders, drills and dozers.
Challenges to plan for
- A component that fails before its planned change, because its history was incomplete
- Planned servicing that cannot proceed because parts are not in stock
- Defect reports that are vague, so the workshop spends the first shift diagnosing
- Several machines falling due for major servicing at once, because they entered service together
Who it is for, and its limits
This suits a mine operator or a mining contractor maintaining a heavy fleet. It fits operations where downtime costs production and where component failures are expensive. It does not fit a small operation with a handful of machines serviced by a local workshop on an ad hoc basis, and it is not a dispatch system: it plans when machines are available, dispatch decides how available machines are used.
A maintenance system does not stop machines failing. It makes failures rarer, planned and cheaper, by replacing components before they fail and servicing on schedule. Costs vary with fleet size and machine types, so confirm with a quote after the fleet is scoped.
Frequently asked questions
What is component life tracking?
Tracking operating hours for major components against their expected lives, so a component is changed during a planned stop before it is likely to fail, rather than after it fails in production.
How do operator defect reports work?
An operator reports a fault against the machine, with what they saw or heard. The report is triaged into a job with priority, and safety-critical defects stop the machine until cleared.
What if parts are not available?
The system flags the shortage before the job is scheduled, so the planner can order parts, reschedule, or accept the risk knowingly, rather than discovering the shortage with the machine already stripped down.
Does the system handle tyres?
Yes, where tyre life matters. Tyres are tracked as components with their own histories, because tyre costs and failures are significant for haul fleets.
Can a component move between machines?
Yes, and its history moves with it. That is essential: a component's remaining life depends on its total hours, not on the hours since it was fitted to its current machine.
