eng.mine-ventilation-flow Calculator
Calculates mine ventilation flow requirements and fan sizing from heat load, diesel emissions, and blast fume dilution. Mine ventilation consumes 40–50% of mine electrical energy — optimising fan scheduling and airway resistance is the primary energy saving opportunity.
Inputs
Face Length M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Advance Rate M Day
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Gas Content M3 T
Reference formula or conversion factor shown for context.
Coal Density T M3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Dilution Limit Pct
Reference formula or conversion factor shown for context.
Results
required ventilation flow Q (m³/s)
The value at the specified point or condition.
coal production (t/day)
The result of multiplying all input values together.
gas emission rate (m³/s)
The value at the specified point or condition.
Q = gas_rate / CH4_limit
The value at the specified point or condition.
1% CH4 limit
Reference formula or conversion factor shown for context.
