## Mine Ventilation Airflow Calc Description
Planning underground ventilation and need to know the required CFM for your crew size, diesel equipment, and airway dimensions? This calculator gives you MSHA-compliant airflow requirements in seconds.

Select mine type (coal, metal/non-metal, or tunnel), enter airway shape and dimensions, and specify personnel and diesel HP underground. Get required airflow, air velocity, and resistance calculations instantly.

WHAT YOU GET:
- Required CFM based on personnel count (MSHA minimums)
- Diesel dilution airflow requirement
- Airway cross-section area for rectangular, arch, or circular openings
- Air velocity at the calculated flow rate
- Airway resistance using Atkinson friction factors
- Fan pressure requirements

MINE TYPES:
Coal (30 CFR 75.325), Metal/Non-Metal (30 CFR 57.8520), and Tunnel — each with correct minimum CFM per person and velocity requirements.

AIRWAY SHAPES:
Rectangular, arch (horseshoe), and circular — with proper area and perimeter calculations for each.

RESISTANCE:
Atkinson friction factor input with typical ranges for smooth (40-60) and rough (80-120) airways.

Works completely offline. No account required. Built for mining engineers, ventilation planners, and safety officers who need fast, MSHA-referenced airflow calculations underground.
