Diesel Airflow — 14 t LHD Loader
Statutory-style airflow requirement for a 14 t lhd loader from engine power and the jurisdiction's rate.
The LHD is usually the thirstiest single machine in a development heading. At the common 0.06+ m³/s-per-kW rule a 250 kW loader wants ~16 m³/s — more than many auxiliary duct legs deliver, which is why loaders idling in dead headings set off DPM alarms first.
Formula
Note: Mine ventilation is statutory and life-safety territory: airflow quantities, gas limits and re-entry times must be set by the registered ventilation engineer/manager under your jurisdiction's mining regulations — this calculator is a planning and training aid.

About Diesel Airflow — 14 t LHD Loader
Diesel Airflow — 14 t LHD Loader computes the governing relationship Q = P_engine × rate × n_simultaneous live as you type. The LHD is usually the thirstiest single machine in a development heading. At the common 0.06+ m³/s-per-kW rule a 250 kW loader wants ~16 m³/s — more than many auxiliary duct legs deliver, which is why loaders idling in dead headings set off DPM alarms first. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Diesel Airflow — 14 t LHD Loader
- 1Enter your values — Engine rated power, Airflow rate per kW, Machines operating simultaneously (sensible defaults are pre-filled).
- 2Read the live results: Required airflow.
- 3Check the "with your numbers" line to see Q = P_engine × rate × n_simultaneous substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Diesel Airflow — 14 t LHD Loader?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula Q = P_engine × rate × n_simultaneous with authoritative sources cited on the page (MSHA 30 CFR Parts 57/75 — Ventilation standards; McPherson, M.J., Subsurface Ventilation and Environmental Engineering)
- ✓The LHD is usually the thirstiest single machine in a development heading.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the diesel airflow — 14 t lhd loader use?+
It evaluates Q = P_engine × rate × n_simultaneous, exactly as published. Sources: MSHA 30 CFR Parts 57/75 — Ventilation standards; McPherson, M.J., Subsurface Ventilation and Environmental Engineering. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
The LHD is usually the thirstiest single machine in a development heading. Mine ventilation is statutory and life-safety territory: airflow quantities, gas limits and re-entry times must be set by the registered ventilation engineer/manager under your jurisdiction's mining regulations — this calculator is a planning and training aid.
When is this calculator the right tool for the job?+
Statutory-style airflow requirement for a 14 t lhd loader from engine power and the jurisdiction's rate. A free mine ventilation & air quality tool. At the common 0.06+ m³/s-per-kW rule a 250 kW loader wants ~16 m³/s — more than many auxiliary duct legs deliver, which is why loaders idling in dead headings set off DPM alarms first. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
