The constant air quantity β is mainly dependent on the ore handling system and, to a certain extent, on the overall mine production rate. For mines where rock is transported through a decline using diesel powered truck haulage or there is no crushing of the mined rock, a suitable value of β is 50 m 3 /s. This typically increases to 100 m 3 /s …

That is equivalent to having less than 150 m of 1400 mm (55") standard duct installed on a twin 110 kW (147 hp) fan. This also assumes no holes in the duct. However, in most mines, it is not possible to run 1400 mm duct into an ore drive and therefore it is reduced to 1220 mm (48"). This, combined with leakage, has proven to be a constant ...
