Diesel Airflow — Scissor Lift / Charger
Statutory-style airflow requirement for a scissor lift / charger from engine power and the jurisdiction's rate.
Explosive-charging platforms occupy headings AFTER the blast's airflow demand has been planned — their own diesel demand is small but additive to post-blast clearance needs. Charging crews in marginal headings notice it as the heading that never quite clears its haze.
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 — Scissor Lift / Charger
Diesel Airflow — Scissor Lift / Charger computes the governing relationship Q = P_engine × rate × n_simultaneous live as you type. Explosive-charging platforms occupy headings AFTER the blast's airflow demand has been planned — their own diesel demand is small but additive to post-blast clearance needs. Charging crews in marginal headings notice it as the heading that never quite clears its haze. 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 — Scissor Lift / Charger
- 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 — Scissor Lift / Charger?
- ✓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)
- ✓Explosive-charging platforms occupy headings AFTER the blast's airflow demand has been planned — their own diesel demand is small but additive to post-blast clearance needs.
- ✓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 — scissor lift / charger 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?+
Explosive-charging platforms occupy headings AFTER the blast's airflow demand has been planned — their own diesel demand is small but additive to post-blast clearance needs. 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 scissor lift / charger from engine power and the jurisdiction's rate. A free mine ventilation & air quality tool. Charging crews in marginal headings notice it as the heading that never quite clears its haze. 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.
