Fig. 6.8 Arrangement of main fans in a mine: a series, b parallel, c combination. Modified from
Ramani (1992)
As for the combined arrangement (Fig. 6.8c), it allows each zone of the mine to
be ventilated by a specific fan. This ensures that each fan ventilates a shorter circuit
lenght. However, in this system, the functioning of each fan influences all the others.
