Ventilation Basic Mining Process/Terminology

mine design relating to mining direction A small quantity of air may flow through mine workings naturally but this would be insufficient and uncontrolled and therefore it is necessary to provide a mechanical means of ventilating the mine. The state of the mine ventilation needs to be monitored to ensure that the quantity of air is
