Airway Resistance — Conveyor Drift
Atkinson resistance and frictional pressure loss for a conveyor drift at its design airflow.
A belt structure eats both area and smoothness, and regulations often cap conveyor-drift velocity near 4 m/s to keep coal dust asleep on the structure. The resistance here assumes clean structure; spillage piles act as orifice plates the survey will find before the calculator does.

About Airway Resistance — Conveyor Drift
Airway Resistance — Conveyor Drift computes the governing relationship R = k·P·L/A³ · p = R·Q² [Atkinson] live as you type. A belt structure eats both area and smoothness, and regulations often cap conveyor-drift velocity near 4 m/s to keep coal dust asleep on the structure. The resistance here assumes clean structure; spillage piles act as orifice plates the survey will find before the calculator does. 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 Airway Resistance — Conveyor Drift
- 1Enter your values — Friction factor k, Airway length, Cross-section area, Perimeter and more (sensible defaults are pre-filled).
- 2Read the live results: Resistance R, Pressure loss, Air velocity.
- 3Check the "with your numbers" line to see R = k·P·L/A³ · p = R·Q² [Atkinson] substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Airway Resistance — Conveyor Drift?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula R = k·P·L/A³ · p = R·Q² [Atkinson] with authoritative sources cited on the page (McPherson, M.J., Subsurface Ventilation and Environmental Engineering; Hartman et al., Mine Ventilation and Air Conditioning, 3rd ed.)
- ✓A belt structure eats both area and smoothness, and regulations often cap conveyor-drift velocity near 4 m/s to keep coal dust asleep on the structure.
- ✓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 airway resistance — conveyor drift use?+
It evaluates R = k·P·L/A³ · p = R·Q² [Atkinson], exactly as published. Sources: McPherson, M.J., Subsurface Ventilation and Environmental Engineering; Hartman et al., Mine Ventilation and Air Conditioning, 3rd ed.. 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?+
A belt structure eats both area and smoothness, and regulations often cap conveyor-drift velocity near 4 m/s to keep coal dust asleep on the structure. 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?+
Atkinson resistance and frictional pressure loss for a conveyor drift at its design airflow. A free mine ventilation & air quality tool. The resistance here assumes clean structure; spillage piles act as orifice plates the survey will find before the calculator does. 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.
