The purpose of face ventilation is? to clear away smoke, steam, and dust, to dilute gases that are inflammable or noxious to render them harmless, to provide air containing sufficient oxygen, and to prevent the excessive rise of temperature or humidity which may be harmful to the health of persons working in the face. The face ventilation i.e ventilation of headings, ventilation of ventilation districts, mine including old workings, etc. This applies to all parts of belowground mines. The major difference between main ventilation and face ventilation is the number and nature of the ventilation control devices (fans, stoppings, doors, regulators, and air-crossings). The Air circulation is achieved by creating a pressure difference between the mine workings and the surface through the use of fans.
The objective is to reduce the likelihood of getting injury & occupational health problems to all persons working belowground mines due to failure in identifying the hazards of ventilation- Gas-Inflammable & poisonous etc., dust, temperature & humidity, etc., during installation operation and maintenance of fans (Main Mechanical Ventilator, Booster fan, Auxiliary fan) and ventilation appliances (Brattice, Stoppings, Doors, Air Crossing, etc.) and coal getting process.
