Auxiliary Equipment Ventilation. Should fire be a concern at the installation, a thermal or carbon monoxide sensor could be installed and provisions made to automatically stop the fan and open a regulator at the back end should it be activated. This would prevent fumes from entering the intake airway or escapeway. What about the heat being put back into the mine intake system? In some

Ventilation. Good quality air has to be provided for personnel to breath, to dilute both natural and introduced ( diesel exhaust) gases, to dilute or carry away dust and to provide cooling for personnel and machinery. 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
