Rhiwbach rockfall at top entrance

nwmines
Update from Miles:
Just letting you know that there has been a fall at the top exit in Rhiwbach (the main exit, not the airshaft). The brow high above the gate has come away and there is a pile of fresh debris on the floor. You have to climb over the fall to get out.
There is still some loose stuff up on the brow, a few rocks are still waiting to come down.
No doubt a result of ice thawing.
Although it’s not massive, I would recommend closing that route until it settles down. If someone could abseil down to the brow from above, I bet a lot of the loose stuff could be knocked out.
Cheers

Rhiwbach update (21st March 2013)

nwmines

Following todays inspection there is still a little concern with the brow above the rafting pool.

Before we use the raft with groups the mine engineer has advised us to paint a crack that he highlighted and monitor it for change for a few weeks before re-instating the raft crossing.

I’ll try and get the crack pained in the next few days

Rhiwbach Lock Damage

nwmines

Hi All,

For those who weren’t in Rhiwbach today, the entrance padlock was smashed off at some point yesterday. We’ll get a replacement put on as soon as possible with the same padlock code, however given some previous incidents its worth double checking any fixed ropes etc before using them.

Wrysgan update (Jan 2013)

nwmines

You may, or may not, be aware of a recent report from some of the Blue Peris staff (via Baggy) about the possibility of rock fall within Wrysgan. The original report (16th Jan) says some of Baggys staff heard what they described as a “large roof collapse” suspected somewhere on floor 1, but heard from the far end of floor 2.

Staff from Dol y Moch have had a look around the mine and found what they suspect to have been recent rock fall on floor 2, just to the left of where the climb up from floor 2 to 3 is, and a flake (60cm sq approx) that looks like its coming away from the roof, as well as evidence of some recent fall. They also noticed some possible movement near the entrance to the man-way from floor 2 to 1.

I’ve been away for the last few months, but plan to pop into Wrysgan in the next week or so to have a look. At the moment I’d suggest groups avoid gathering to the left of the handline from floors 2 to 3, and also avoid the area beyond the manway entrance (which is off the blue route anyway). I’ll inform Dave Carlisle at his next visit unless anyone visiting the mine find more evidence of movement.

Thanks to all those who been reporting and checking the mine, please do remain vigilant and report any changes. 

Rhiwbach Brow

DO NOT USE THE RAFTING POOL UNTIL FURTHER NOTICE

We’ve been monitoring the brow above the rafting pool for several months. In September 2012 a team of us went in to re-peg the brow following the one tell-tail peg being found floating in the water. RhiwbachBrowSept12_LR

A few weeks later a significant amount of the brow fell!

We’ve cleared as much as possible however should not re-use this section of mine until it’s been checked by a qualified mine engineer.
