underground trackless mining equipment small ends 2.2 mx2 2m

model an underground mining entry, which is 5m (16.5ft) wide by 2.2m (7ft) high. The 1.2m (3.5ft) wide by 12.2m (40ft) long box was built along the right side of the entry to simulate an uncut slab of coal. The resulting entry simulated a 4m (13ft) wide box cut. The exhaust fan draws approximately 5.9m. 3 /s (12,500cfm) of air through the gallery
