Inspection (Wrysgan and Geironydd) update, March 2017

Inspection (Wrysgan and Geironydd) update, March 2017

Inspections are going well. Today we looked at Wrysgan and the Geironydd trials.
There was very little of concern in both, however our mine engineer has suggested we monitor the brow of the adit that leads outside on floor 5 of the mine (the wet way out) as there looked to be some blocks that look like they may fall at some point, although there’s no evidence of a fall on the floor. This is the exit directly next to the eased block that fell several years ago (photo attached) directly above the solid ladder, and potentially somewhere groups may gather having scrambled up the ladder.
Also within Geironydd the frequently used trial (opposite the waterfall that drops into a short adit) had several bats in the back of the stope. There is a circular route that follows the back of the stope around several timbers and drops down via a short slide/slab. It may be prudent to avoid that section of mine in the Winter as the bats are hibernating.

Rhiwbach Update (and gate code change)

Rhiwbach Update (and gate code change)

Work has continued today to get the steel carried into the mine in place (thanks again to the Go Below staff for the work).

However we could do with some help on Saturday morning (10:30am at the Cwm car park) shifting more stuff into he mine (including a second boat).

Please get in touch if you’re able to help.

Also during the mine inspection week, on Thursday the 30th of March, the gate locks will be replaced with new, and the code changed. Contact whoever you’re working for to get the code.

Thanks!!

Thanks to all who came along this afternoon to help move the steel into place in Rhiwbach. What started as a plan to get the steel partway up to the mine ended with all the materials in the mine within an hour!!

Go Below will get in touch when they plan to instal the steel as users will need to stay clear of the mine that day.

As we were there we also installed an additional anchor on the traverse (floor 1) to try and eliminate the rub point, it will need a stainless steel mailon.

Some updates

There’s been a few updates sent out to users of Rhiwbach, Wrysgan and Bwlch y Plwm. Would be worth checking with whoever you’re working for if you’re heading underground with groups.

We’re also looking to get a working party up to Rhiwbach Friday afternoon. Get in touch if you’re free to help carry some heavy stuff up to the mine! Did I sell that….

Wrysgan Rock fall

Sounds like there’s been a small (but worth taking note of!) rock-fall above the traverse on floor 3 of the mine:

Hi Gethin,

Picture attached of a recent rock fall in Wrysgan. Abseil stance at the end of the L3 traverse, after the island!

Obvious missing bits from the roof but I couldn’t see anything hanging….waiting to drop!!

Couple of pieces managed to make it down to L2 at the bottom of the pitch!!
