A horizontal mine shaft is called an adit. It is a passage or tunnel that connects the surface with underground mine workings for access, ventilation, and transportation of materials.

A deep shaft mine is an underground mining operation where tunnels are dug vertically into the earth to extract minerals and resources. These mines can extend hundreds to thousands of feet below the surface to reach deep deposits. Workers and equipment are lowered into these shafts to access and transport materials to the surface.
A horizontal shaft into a mine is called an adit. Adits are used for access to underground mines and are typically driven into the side of a hill or mountain.
The two parts of a lift that go down in a mine are called cages. These cages are used to transport miners and equipment up and down the shaft.
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.
A shaft is a hole dug in a mine.
Cliffs Shaft Mine Museum was created in 1880.

The mine shaft was over 500 feet deep. The shaft of the wagon was broken.
If you drop a grand piano down a mine shaft you would get a flat minor.
The allusion in "shaft" often refers to a long, narrow passage or tunnel, especially in a mine. It can also allude to a vertical or nearly vertical opening in the earth, like a well or a vent.
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.
Shafts are dug to provide access to deeper layers of the earth where diamonds are found. This allows miners to extract diamonds from underground deposits efficiently and safely. The shaft also provides ventilation, transportation, and a way to bring equipment and workers in and out of the mine.
