Underground Mine Ventilation

Underground Mine Ventilation Technical Aspects of

Ventilation of underground mines Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the U/G workings to achieve these purposes, ensuring proper distribution use of the air, and controlling the return to surface of contaminated air.
