Mine Ventilation
Mining is the extraction of valuable minerals or other geological materials from the earth. Any material that cannot be grown from agricultural processes or created artificially in a laboratory or factory, is usually mined.
Fans are the most important component of any mine ventilation system as they generate the amount of air flow required to clear toxic fumes while creating enough pressure to do so.
