It is like the length of a road .. roads twist and turn so the length is
longer than the straight line distance.
The 'depth' of a tunnel is the straight line distance, not the distance
you travel by going along it as it may twist and turn.
I am afraid 'English' words have many meanings! It may have been better
to define vertical depth as a negative height value e.g.
height=-15 would be a 'depth' of 15 metres.. too late now.

Then I would suggest "length" is what you mean here, as it has no
direct relation with the distance from the surface.

B) the distance one would have to travel to reach the end of the adit
This. Any straight-line distance can be determined reasonably easily
from a map, using its scale and a piece of string. A length of a
twisty path, not so much. Granted, adits aren't usually _that_
twisty, but entering a mine is always a potentially hazardous
undertaking and it's important to have as much useful information at
hand as possible.
