Diagnose equipment defects+
Trace the source of the boom oscillation on the 772 excavator: reproduce the fault under controlled lift, log vibration data, strip down the linkage to inspect pins and bushings, swap suspected components with the spare boom, and update the defect report with findings and recommended repair hours.

Repair damaged or worn parts+
Repair the worn final drive on haul truck 789: remove the wheel assembly, replace the damaged gear and bearings with parts from bay B3, check shaft runout, refill to spec, torque to chart, test under no‑load and light‑load, then close the work order and attach parts used and labour time.

Read operating manuals and technical drawings+
Work through the operator manual and technical drawing set for the new jaw crusher: verify service intervals, note torque specs and hydraulic line routing, mark critical lift points and safety limits, photograph unclear sections, and produce a one‑page safe‑work summary for the crew toolbox talk.

Adjust and maintain industrial machinery, using control and regulating devices.+
Adjust the conveyor drive regulators on the No.3 crusher, set control parameters to maintain 1200 rpm under load, log the changes in the maintenance register, and run a 30-minute load test to confirm stable operation.

Clean parts by spraying them with grease solvent or immersing them in tanks of solvent.+
Degrease the hydraulic pump covers and gearbox housings by spraying solvent, then immerse removable bearings in the solvent tank, inspect for pitting, dry and re-lubricate before returning parts to the No.2 haul truck.

Troubleshoot mechanical issues+
Diagnose the JCB loader vibration by road-testing at idle and full throttle, isolating source to either loose coupling, bent shaft, or bearing wear, document fault codes and recommended repairs for the service planner.

Handle and move objects+
Lift and position the 600 kg gearbox from stock to the service bay with the overhead hoist, secure on the bench, tag orientation and mounting points, then move the old unit to the disposal pallet for return to stores.

Make decisions and solve problems+
Decide whether to repair or replace the worn bearing set on the primary mill by comparing downtime cost for a six-hour repair versus a 24-hour replacement, consult with operations lead Sarah, then record the chosen action and rationale in the maintenance log.

Can AI actually do this job?

the honest answer

It can

where it genuinely helps
  • Explain the theory behind the work
  • Draft, tidy and structure your writing
  • Rehearse a hard conversation before you have it
  • Build a study plan that fits your gaps

It cannot

where it stops, completely
  • Be in the room where a mechanic actually works
  • Carry the responsibility when the call is wrong — that weight stays yours
  • Notice what no one wrote down: the hesitation, the thing left unsaid
  • Live with the outcome

Questions people actually ask

You spend most of your day inspecting, testing, and fixing heavy equipment—haul trucks, loaders, conveyors, or crushers. Expect scheduled checks in the morning, running diagnostic tests, and repairing worn or damaged parts during the day.

You also update maintenance records in the maintenance management or fleet management system, communicate issues to operators by email or Microsoft Outlook, and do inter-shift handovers so the next crew knows what’s been done.

Begin with a trade school or community college program in diesel or heavy equipment mechanics, then get hands-on apprenticeships at a mine or equipment shop. Focus on reading operating manuals and technical drawings—those are used daily.

Practice diagnostics and troubleshooting on real engines and hydraulic systems, and learn to use maintenance management and recordkeeping systems employers use to schedule work and log repairs.

You’ll use common hand tools and shop tools plus diagnostic scanners for engines and control systems. For office-side work you’ll use maintenance management and fleet management software for work orders and Microsoft Word or Outlook for reports and communication.

Recordkeeping is expected—log tests, parts replaced, and inspections in the company system so shifts can track recurring problems and parts inventory.

According to the U.S. Bureau of Labor Statistics (BLS, 2025), mechanics in this occupation group had a median annual wage of $65,510. The lowest tenth earned $46,820 and the top tenth earned $94,460.

BLS also reports about 176,600 employed in the field. Local pay varies by mine, state, and overtime or shift premium, so use these numbers as a national baseline.

Mining mechanics work on much larger, heavier systems—mobile mining machines, crushers, conveyors—so you deal with hydraulic systems, heavy-duty transmissions, and structural parts rather than small car engines.

You also use maintenance management and fleet management systems and must do formal inter-shift communications and testing protocols that most auto shops don’t require.

AI can help suggest diagnostic steps or find technical manual excerpts, but always cross-check against the machine’s operating manual and the manufacturer’s procedures. Never rely solely on AI when safety-critical decisions (brakes, brakes systems, structural repairs) are involved.

Keep records in the maintenance management system of how you reached a diagnosis and what tests you ran. If AI suggests a fix, test it under controlled conditions and follow lockout/tagout and safety rules.

Learn systematic troubleshooting: run tests, read error codes, compare results to the manual, and isolate the failed component. That directly maps to tasks like diagnose equipment defects, test mine equipment, and repair parts.

Also get comfortable with recordkeeping and the maintenance management system—good logs and clear inter-shift communication cut repeat failures and show you understand the full repair cycle.
