Mining. High air volume portable skid mounted axial fans operate underground to supply ventilation for mine workers. Fans range from 72″ to 144″ diameter and are capable of producing from 90,000 CFM to 350,000 CFM each. Above ground, double-width double-inlet centrifugal fans pressurize the mine shafts with fresh dilution air.

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. In mines where a fan failure may …

The primary ventilation system provides the necessary paths for air to flow in and out of the mine. This system composes of Primary Fans (also known as Main Fans), which pump fresh air into the mine and remove contaminated air from the mine. Large fans typically mounted on the surface or below ground, suck the air through the mine at 150 cubic ...

Ventilation operating costs are often a significant proportion of the total electrical energy costs on site, and being able to ventilate in the most efficient manner saves significant operating costs. AC drives are well recognized to be the most flexible, energy-efficient, low maintenance method for controlling mine ventilation fans.

Several site visits were conducted to audit the ventilation system in order to both identify possible system improvements and to increase efficiency. A series of time-phased …

Mine ventilation offers numerous opportunities for energy and cost savings. In designing mine ventilation systems, TLT-Turbo aims for the best possible system efficiencies. Through aerodynamic optimization, smart drive technology and blade adjustment we are able to reach fan efficiencies of up to 90% and system efficiencies of up to 85%.
