an airshaft.
Shaft mining is the earnest form of underground mining. Underground mining is selected when the rock or mineral is so far to reach using surface mining. Shaft mining is the kind of mine that you normally see in movies where the miner travels straight down into a profound, dark tunnel until he reaches the base. The shaft mine has a vertical man shaft, a tunnel where the men travel up and down in an elevator. Equipment is taken into the mine using this shaft, too. Short tunnels to the ore are dug from that man shaft. When the ore is dynamited and broken into chunks, it is taken to the top and loaded into trucks through a second shaft. There is usually an air shaft that gives the mine ventilation. When we visited a coal mine, it was amazing how much air moved around in the tunnels. Moving air removes the gases that occur naturally underground.
My research concluded that, thanks to the knowledge of the Eagle Air Shaft by mine surveyor Joe Stella, 33 miners were able to escape through it.
They have a turbine that acts as motor, and when air pressure turns it they rotate. Air nailers use air pressure on a diaphragm to fire a small shaft that does the action.

Density and air pressure will increase, while altitude decreases.
whenever the bus or train starts moving, there will be a shaft connected to the wheel mechanism which will be rotated. By rotating the shaft the power will be generated which is stored in the batteries. this stored power will be utilised for running the air conditioner.
Miners light a fire beneath a shaft to create an updraft that helps circulate fresh air into the mine. This improves ventilation for the miners working underground by pulling out stale air and harmful gases.
A senior flex shaft is a very flexible lightweight golf shaft which is ideal for senior golfers. They usually have a low kick point which is ideal to get the ball in the air with the slower swing speeds of a senior golfer.
There might be mold inside the air shaft or there is something smelly near it and it's scent is being blown
