winze

Round the next bend I found a narrow winze going off to the right.

A narrow winze took me down into a broader gallery.

I went down the winze and turned left into a narrower gallery, following the air.

I came to a winze and peered down it.

"There's one winze that would take the lot."

The winze sloped down to a drift, which narrowed till it was no wider than my body.

Such techniques may also be used inside a mine to explore a winze, shaft, or steep incline.

He waited for an hour after full darkness, then made his way through the narrow winze that had eroded past the end of the steel wall.

The top of a winze is located underground, in contrast to a shaft where the top of the excavation is located on surface.

Water can also cover up a winze, which is a shaft within the mine, or entrap dangerous gases in which are released upon disturbing of the surface tension.

A winze is an opening in an underground mine that is sunk downward (as opposed to a raise, which is mined upward) from inside to connect lower levels.

When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft.
