The purpose of face ventilation is? to clear away smoke, steam and dust, to dilute gases that are inflammable or noxious so as to render them harmless, to provide air containing sufficient oxygen and to prevent excessive rise of temperature or humidity which may be harmful to the health of persons working in face.?
The  face ventilation i.e ventilation of headings, ventilation of ventilation districts, mine including old workings etc.. This is applicable 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. 

Course Objective

The objective is to reduce the likelihood of getting injury & occupational health problem 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.
