Looks like a success that ended well - no life threatening injuries. What I noticed was the statement that a carabiner "broke" causing a fall of 40 to 50 feet.

Carabiners don't break; at least biners rated for climbing and used in anything like normal usage. I wonder if an ersatz biner not rated for climbing was employed; some are the same size as real biners and superficially look the same.

Mine rescues are extremely complex, especially when dealing with vertical shafts. They are much more unstable than cave passages.
