Theory 068/Mining & Minerals
Ventilation Is a Leakage Ratio
The claim
Mine ventilation cost is set by the ratio of leakage to useful airflow rather than by fan power.
01The mechanism
Leakage bypasses the workings, so power spent on it delivers no ventilation; the ratio sets effective cost.
02Predictions
- P1Cost should track the ratio.
- P2More fan power should not fix leakage.
03Refutation
Cost tracking fan power would remove the leakage term.
