Re Alternative names for shafts (by which I assume
vertical or near vertical mine entries, What a can of worms Philip has been
opened..
In reply to David Hardwick the answer is Yes,
a level can be a wholly underground roadway or it can run in from the
surface.
For instance in the Nth Mt Lyell Mine (copper)
in Tasmania In references to the 1912 disaster, it was stated that
the mine had some 15 or so levels of which the top three (ie Nos 1 , 2 and
3) were accessed directly through portals in the mountainside, the lower
ones by an internal shaft with the electric winding engine and associated
headgear in an underground chamber so that the men walked in along No
3 level to the cage.
By the way, "soughs" , "adits" and the like
were certainly mine entries but could never be described as "shafts"
