Odin Mine - loose bolt on entrance pitch
« on: August 29, 2021, 03:59:53 pm »
3 of us SUSS members took a short trip in Odin Mine today.

Of note was a loose bolt on the entrance pitch (after the ab in to the rake) - it's the 4th bolt in, but is easily bypassable if you're happy doing a single hang coming off the traverse. Have notified DCA but just watch it if you're in there any time soon.

Hmm, I think that might be the old DMM we doubled-up.

That's what I said! Good job we backed it up. Another trip to Odin with a drill it'll be then.

It's a shame you missed the rest, although your description of sand and pebbles in the roof does hint at why bolting that floor-collapse was so important. Ironically the cartgate section is easily the most stable part of the trade route! The 'squeeze' under the first stone stemple is only a squeeze because loads of shale grot from the floor-collapse landed there. Dragging the bolting kit through was bad enough, without us resorting to taking in shovels too, so if someone could spend a mere fifteen minutes on a future trip just digging that rubbish out, it would be a great help, and it wouldn't be a squeeze no more - there's plenty of room in the floor-pit you traverse over, as that's where the rest of the collapse is. There used to be as short downward passage there, with digging potential, but it's not there any more. And that stemple weighs about 200kg, so you really don't want it on your shoulders as you pass through!

James Blake went up yesterday and removed the old DMM anchor that had started to move and replaced it with a new BP anchor. This anchor is still to be tested, so don't use it unless the tag has been removed. When this old anchor was tested a few months back it must have cracked the resin a bit and left it to become wobbly with increased use recently. It took a significant effort to remove even though the resin bond was broken. The original placement was drilled out, cleaned and re-used.
