monitoring is especially critical if the dust contains quartz or other components caus-
ing lung disease.
In planning the ventilation system, engineers should establish mine ventilation net-
work computer models and design airways and fans so that sufficient ventilation can
be achieved in all mine workings at the farthest extent of the mine network. It is impor-
tant to provide adequate airway cross sections to deliver the required airflow while
maintaining acceptable fan pressures and power requirements. If larger cross sections
cannot be mined due to ground control limitations, parallel airways should be consid-
ered to deliver sufficient amounts of air.
Continuous monitoring of air flows, pressures, and air quality is an essential ele-
ment of mine ventilation management. Also, ventilation engineers should maintain an
up-to-date ventilation model of their mines to make accurate ventilation projections as
mine development progresses and new mining sections come on line.
