Ladders and staircases in shafts, still popular:
Ellington Colliery had a spiral staircase down a staple shaft between two levels. The staple was also shared with a chute for coal from a conveyor at the top to one at the bottom.
That Polish salt mine above has a exquisite timber staircase down one shaft for entering the mine, and the usual cage and winder in the 2nd shaft for exit.
I did some work in the cable shafts of an underground hydro power station that had ladders and platforms not unlike the 1901 image above, but vertical steel ladders and steel platforms: here is an image of one those very shafts under construction back in the 60s:

I used to zip up and down those cable shafts many times in a day's work. I'm gasping just looking at them now.
