Ventilation rules of thumb – friend or foe? Focusing on design upcast air velocities for shafts and raise bores
By A S. Derrington
There are several long-standing rules of thumb that are often quoted in mine ventilation studies. They include airway ‘carrying velocities’ and the critical upcast air velocity range that must be avoi
