The ventilation system at Geevor was crucial in maintaining a safe working environment underground.
The main purpose of the circulating air was to provide breathable air, reduce or control the working temperature and to remove smoke and gases produced from blasting.
The ventilation system consisted of fans situated on top of a number of old shafts to draw foul air out of the mine while the fresh air was drawn down Victory and other shafts and directed to where people were working. This was achieved by a series of ventilation doors, and the use of booster fans in dead end development tunnels. The Victory shaft is an upcast shaft, you can feel warm air coming up in the winter.
