Rafting Brow

22 MineReports2013 Rhiwbach Boating Brow PictureFollowing this years inspections (reports will follow soon, just waiting on some final content) we where advised to paint a few cracks in the brow above the rafting pool and monitor them for 3 weeks. The cracks where painted on the 6th of April. We’ll need to monitor the marked areas to see if the brow has stabilised before re-installing the boat trip. Please continue to avoid this area with groups.

Top Entrance

22 MineReports2013 Rhiwbach Top Exit PictureLast week Miles pointed out some loose rock above the top entrance to the mine, most likely a result of the freeze/thaw. Over the weekend we also removed some sizeable blocks hanging above the entrance! Click here to watch some film footage.

The bulk of the loose rock has been removed, and the path leading from the entrance cleared of debris. Having confirmed this with Les Riley (mine engineer), we can continue to use that entrance. However I would advise all groups leaders to monitor the quarry roof, and move groups swiftly away from the entrance/exit.

Thanks to both Sharon and Ross for helping out.

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)

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.

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.
