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

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.

Redefining mine ventilation efficiency and cost savings

Nov 27, 2020· The A&B fan range solutions are designed to replace the traditional, large primary ventilation fans with a simple, “plug and play”, modular design, using the same fans which are also designed to be used underground. This concept allows a mine to keep standardised spares, therefore improving reliability and availability of the fans.
