Fan Selection For Large-Opening Mines: Vane-Axial ,
axial and propeller fans were investigated and tested at four large-opening mines to assess the effects of fan location on recirculation and entrainment Each fan type has its own airflow, entrainment and penetrating air-
In Chapter 4, mine fans were classified in terms of their location, main fans handling all of the air passing through the system, booster fans assisting the through-flow of air in discrete areas of the
Both axial and centrifugal fans are used to provide air circulation in mine ventilation systems, with fan efficiencies of over 80% being achievable The selection between axial flow or centrifugal for main mine fans depends on cost, size, pressure, robustness, efficiency and any performance variation
