Schauenburg Mining Ventilation

Schauenbug Flexadux Corporation is providing this handy guide for designing an auxiliary mine ventilation system. We would be happy to discuss your own personal needs – and answer your questions – just by contacting us. We can also provide you copies of all of our brochures that include other useful reference guides and materials. These pages have detailed information, charts and calculations and may be slow to download.

You can learn more about mine ventilation standards by visiting the United States Mine Safety and Administration’s web site and their specific regulations (www.msha.gov).

Auxiliary ventilation is designed to provide adequate ventilation to a dead-end entry or tunnel, to remove or dilute hazardous gasses or dust and to provide sufficient and clean air for individuals and equipment to work efficiently.

Considerations:
Quantity of air required	Velocity of air in the entry or tunnel Air quantity for diesel equipment Air quantity for people Air required to dilute or remove gasses and dust Air required for cooling or other needs
Physical constraints	Head room over haulage or material transport equipment Length of ducting Handling and hanging problems Potential for damage from blasting and other activities
Other considerations	Ducting and fans must be sized to ensure that the fans are not working in a stall (i.e., the fan attempting to move more air that the duct will allow) A larger duct allows a more efficient and lower horsepower system Legal and contract requirements for fans and ducting Preferred direction of airflow – suction and blowing Most leakage occurs at the joints and longer lengths have significantly less leakage
Evaluate the different types of ducting – Steel, Fiberglass, Flexible Suction, or Flexible Forced – and determine which Schauenburg product is best for your application.
