Underground Mine Ventilation Technical Aspects of Mining

Ventilation of underground mines Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the U/G workings to achieve these purposes, ensuring proper distribution & use of the air, and controlling the return to

Mining Industrial Fans Ventilators and Blowers Aerovent

High air volume portable skid mounted propeller 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.

Mine Fans and Tunnel Ventilation Radial and Axial Fans.

Mines, tunnels and quarries require fans and blowers for ventilation or exhaust gas systems. High pressure axial fans blow air into ducts, tunnels and underground passages. In mining ventilation systems axial fans may be applied to exhaust or in discharge configuration and proper technology may be used to satisfy required specifications.
