Mining Vehicle & Underground Equipment calculator

Underground Duty Cycle Calculator

Estimate underground duty cycle for mining vehicle and underground equipment using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time. Compare two scenarios in seconds before you commit a slot on the schedule.

What this calculator does

  • Estimate underground duty cycle for mining vehicle and underground equipment using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
  • Use it when underground duty cycle in mining vehicle and underground equipment is changing rate or allowance and you want to see the impact.
  • Turns underground duty cycle workload, underground duty cycle completion rate, setup, handling, and delay allowance into a adjusted run time for underground duty cycle in mining vehicle and underground equipment.

Formula used

  • Base underground duty cycle time = underground duty cycle workload ÷ underground duty cycle completion rate
  • Required underground duty cycle time = base underground duty cycle time × allowance factor

Inputs explained

  • Underground duty cycle workload: Enter the required workload from the work order, build plan, test queue, or maintenance job plan.
  • Underground duty cycle completion rate: Use a measured completion rate from a recent production report, time study, test log, or line observation.
  • Setup, handling, and delay allowance: Add the normal allowance for setup, checks, staging, breaks, minor stops, or retest time.

How to use the result

  • Reach for it when a customer asks for a lead time and you need a number you can defend in 30 seconds.
  • Setup, changeover, and major stoppages are not in the formula. Add them on top for mining vehicle and underground equipment jobs that include them.

Common questions

  • Why use this underground duty cycle tool for mining vehicle and underground equipment? Estimate underground duty cycle for mining vehicle and underground equipment using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time. You get a adjusted run time you can defend before quoting, scheduling, or sign-off.
  • What numbers should I focus on first? underground duty cycle workload, underground duty cycle completion rate, setup, handling, and delay allowance usually move the adjusted run time most. Pull from measured mining vehicle and underground equipment runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Run a fast what-if before you change rate, allowance, or crew size on the next mining vehicle and underground equipment job.
  • What can throw the result off? Validate your allowance against actual mining vehicle and underground equipment downtime; an outdated allowance is the most common reason this misses.
