Since 1984, Minetek Air has been delivering innovative, modular air ...
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 …
