mine, but Location 1 saw the most increase in both cases.
The airflow quantity increase at Location 1 was from zero
to around 22 m3/s (46,600 cfm) when the truck was going
in the mine, and while coming out of the mine the maxi-
mum airflow reached was around 11 m3/s (23,300 cfm).
Scenario 4: Modeling with Truck Movement in the
Mine with Fan
In this scenario, a combination of the above two scenarios
were modeled: the truck’s movement and a 3.66- m diam-
eter fan running near the Main Return (Figure 13). Again,
