20 tasks, each one witnessed by the sources that watched the job — and behind every one, a prompt you can use tonight.
You usually start by checking the maintenance schedule in the fleet management system and looking at overnight reports in Microsoft Outlook. Then you inspect heavy equipment — brakes, hydraulics, tires, and control devices — and run diagnostic tests on anything that failed.
Afternoons are for repairs: removing worn parts, overhauling hydraulic or pneumatic systems, and cleaning parts in solvent tanks. You log all work in recordkeeping or maintenance management software and write short repair reports in Microsoft Word or Excel before the next shift handoff.
Fleet management and maintenance management systems track vehicle availability, service intervals, and open work orders. You’ll use them to schedule inspections, assign jobs, and pull equipment histories. Recordkeeping stores inspection and repair records required by the mine.
Microsoft Excel is for parts lists and cost sheets; Word for detailed repair reports and manuals; Outlook for shift communication and parts orders. The systems feed each other: a repair you record in the maintenance system becomes the document you attach in Word or Excel.
Start with the operator’s fault report and the machine’s maintenance history in the recordkeeping system. Run on-board diagnostics and compare symptoms to the technical drawings and manuals. Check the usual failure points: hydraulics, control valves, hoses, and wear items.
If the fault isn’t obvious, isolate systems (electrical, hydraulic, mechanical) and use test equipment. Record test results and the decision path in the maintenance management system so the next mechanic knows what you tried.
Yes, but cautiously. Use AI to summarize manuals, find troubleshooting steps, or pull up common faults for a specific model. Always verify any AI suggestion against the original mechanical mine machinery manuals, manufacturer specs, and your own inspections.
Never let AI replace physical tests. Don’t follow AI wiring or hydraulic layouts unless you confirm them with the machine’s technical drawing or a supervisor. Log any AI-assisted decision in your recordkeeping for safety and accountability.
According to the U.S. Bureau of Labor Statistics (BLS) 2025 data: 176,600 employed. Median pay is $65,510 per year. The lowest 10% earn about $46,820, and the top 10% about $94,460. These are national figures and vary by mine, remote location, shift premium, and union status.
Use BLS numbers as a starting point. Ask your employer how they handle shift differentials, overtime, tool allowances, and hazardous-location pay when you interview.
Get a technical diploma or certificate in diesel or heavy equipment technology and apprenticeships that include hands-on time with hydraulics and pneumatics. Learn to read technical drawings and operating manuals, and get basic computer skills: Excel, Word, and an Outlook email account.
Experience with maintenance management or fleet software is a huge plus. Try to log real hours replacing pumps, overhauling brakes, and cleaning parts in solvent tanks — those tasks map directly to what employers list.
Great mechanics not only fix parts but diagnose root causes quickly and document them clearly. That means using troubleshooting methods, testing equipment, and the maintenance management system to avoid repeat failures.
They also communicate during inter-shift handoffs and train operators on correct machine use, reducing misuse. Practical skills (hydraulics overhaul, pneumatic systems, control adjustments) plus accurate recordkeeping in Excel/Word make you much more valuable.
