Technically, a tunnel becomes a shaft when it's angle of descent (or ascent) exceeds 45 degrees.

Warren's Shaft is an archaeological feature in Jerusalem found by Charles Warren in the late 19th century.
It runs from within the old city to a spot near the Gihon Spring, and after its 19th century discovery was thought to have been the centrepiece of the city's early water supply system, since it would have enabled the city's occupants to safely reach fresh water (which was otherwise unavailable within the city) even if the city itself was besieged.
The narrow and tall shaft was demonstrated to be traversable when a member of Warren's excavation climbed from top to base.
Since in the Books of Samuel it states that David conquered Jerusalem from its prior inhabitants due to Joab sneaking up a similar water shaft and launching a surprise attack on the city from inside, it was long thought that Warren's shaft was the shaft in question (with Hezekiah's tunnel having too late a date, and there being no other known candidates).
A shaft is composed of four sections in sequence:
1,a stepped tunnel
2, horizontal but curved tunnel
3, a 14 metre high vertical shaft
4,a feeding tunnel
According to a number of archaeologists, the shaft is simply a widening of a natural fissure in the rock.
Or a sloping access shaft which travels downwards towards the coal seam. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively.

Wikipedia definition:
A shaft (AKA John Shaft) is a fictional black detective from the 70's. A tunnel is a thing that goes under the ground.
They are very different indeed. A tunnel becomes a shaft when it goes through the Police acadamy and turns into a Black detective from the 70's played by Richard Roundtree.
Good luck on your travels to Russia and afar.

I believe a Tunnel runs horizonally under the earth and a Shaft runs vertically.
