MINE VENTILATION SYSTEMS Ventilation is the control of air movement, its amount, and direction. Although it contributes noth - ing directly to the production phase of an operation, the lack of proper ventilation often will cause lower worker efficiency and decreased productivity, increased accident rates, and absenteeism.

This is no exception in mining. One major concern for safety in mining is proper ventilation in the mine. Improper ventilation techniques can lead to reduced air quality underground, reduced oxygen levels, and even a build up of toxic gases. This is why it is vital to monitor and measure airflow in mine shafts, to properly control ventilation ...
