Mine ventilation is a significantly important aspect of underground mining Improved ventilation clears methane and other toxic gases found in coal and metal mines removes fumes from blasting and exhausts diesel fumes produced by equipment Ventilation provides fresh air to underground mines and removes noxious gases as well as dusts that Abstract In a single working face in an underground mine a single duct and a booster fan are installed to provide fresh air to the working face for local ventilation Since this local ventilation is provided in conjunction with the entire ventilation network of the mine its performance and resulting environment depend on the conditions of air intake and exhaust the duct leakage
