UNDERGROUND MINE VENTILATION SURVEY

UNDERGROUND MINE VENTILATION SURVEY

Most underground coal mines in India employ an exhaust (i.e. negative pressure) ventilation system. This project deals with the pressure and air quantity survey of an underground coal mine ventilation system at Nandira colliery, Talcher. The survey work has been carried out with the help of latest instruments at nearly forty stations.
