understanding the ventilation air behavior and in determining the optimum size of brattice sails, which provide a highly effective contaminant removal from the unventilated mine areas. This, in turn, helps the mine ventilation designers to meet the mine safety requirements. 1 Introduction In underground mining, it is often necessary to provide
Without ventilation, the air in a mine is filled with dangerous contaminants. Miners may work at depths of a mile or more underground where contaminants such as carbon monoxide, as well as the dust created from the mining cycle exist. Worker safety is essential to any mine's operation and success, but also presents challenges.

Mine ventilation fans : Mine ventilation is defined as a combined system of shafting, ducting and a welldesigned combination of fans, mine ventilation is a basic need of mining industries, It is required for providing adequate oxygen for the work force and to dilute and exhaust dangerous gasses in the underground mine, it is also required to take smoke of machine equipment out because many of ...
Ventilation of any underground mine is a process of identifying the potential hazards from a mining system and implementing a ventilation system that ensures the health and safety of the mine worker. To this end, a number of new advances have been made to benefit the engineer in achieving this goal. ... Being complacent in the practice of mine ...
Underground mine ventilation: how to improve safety and half energy costs. In underground mines, air is polluted by diesel vehicles and blasting activity. Mine ventilation is an energy consuming and complicated business, which means there is a large potential to save energy and cost in this area.
Ventilation controls are now recognised as one of the core risk activities in mines requiring the appointment of statutory ventilation officers in both coal and metalliferous mining sectors. With reemergence of pneumoconiosis in mine workers, it is important for all underground operations to contribute to this conference.
