What is an air shaft?

Air shafts are open spaces that are created to allow ventilation to enclosed space. Some examples of air shafts are simply holes that are bored from underground surgery to the surface, ensuring a stable supply of fresh air to the cave or other underground area. In different types of buildings, the air shaft is usually located in the walls and can be used as a pipeline to distribute heated or chilled air throughout the interior space.

The establishment of an air shaft is extremely important for any type of mining operation that requires people to actually go underground, for example in a coal mine. Usually an air shaft is drilled into the tunnel and creates a vertical connection with the surface. Fresh air from the surface is able to flow into the tunnel, so that the workers make breathing easier. It is not uncommon for several air shafts to be drilled along the length of a single tunnel to ensure a continuous flow of fresh air.

The shaft is often included in the original plans for the building and effectively creates a net that connects to each room through an opening in a floor, ceiling or wall. One end of the shaft is often associated with an oven or some type of heating and cooling equipment, allowing control of the internal temperature and also to make sure that the air is constantly refreshed throughout the space.

While many air shafts have a relatively small design, others are large enough to walk a person with an average size if necessary. This is sometimes the case in large mining operations and serves a practical purpose of providing a type of escape route in the case of the collapse of one part of the Tunnel mine. Assuming that the air shaft is large enough, everyone trapped in this section can climb along the shaft and eventually reach the ground level.

The shaft of air flow increases the chances of survival and can often buy precious time, as rescue operations are launched to free workers imprisoned in the tunnel.
