Underground mine ventilation Wikipedia

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.

CDC Mining Breaking the Ice on Booster Fan Dilemma

Booster fans are not allowed in the US bituminous and lignite coal mining operations at the present time due to safety concerns. This paper presents the history of booster fan use in coal mines of the United States during the last 90 years. Changes in regulations, as well as advantages and disadvantages of booster fan use, are discussed.

Utilization of booster fans in underground mines

despite increased potential for recirculation, booster fans are used effectively in other major coal-producing countries such as Australia and the United Kingdom. Approaches specific to coal mine ventilation in other countries are compared to help identify practices that reduce risks associated with the use of booster fans.
