[QUOTE="Pete E, post: 661036, member: 18110"] I had the chance to go down one of the ultra deep goldmines in South Africa, and like you say very scary stuff. The had some sort of drag system on chains bolted to the roof that would drag the mined gold bearing rock from the face...We were standing about 20 yards from the back of this watching a guy operate it when it brought part of the roof down at the mine face...it was only a small collapse and seemed to be business as usual to the miners but scared the crap out of me!
