Background. The main objective of an underground mine ventilation system is clear: to provide air flows in sufficient quantity and quality to dilute contaminants to safe amounts/concentrations where personnel are required to travel and work. This requirement is integrated into the mining .
The highpressure fans currently used in mines can be unsafe, but booster fans can be used to overcome these adverse conditions. This contract will research the use of booster fans in deep coal mines, where coal seams can have over 3,000 feet of overburden, causing ventilation and ground control problems.
Underground Ventilation (Metalliferrous Mines) INTRODUCTION Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub
