Rhiwbach Footpaths

Hi all,

Just a quick heads up that there’s some work going on on the footpaths around Rhiwbach over the next 3 weeks (so into early Sept). Access along the footpaths will remain, however there will be heavy(ish) machinery moving up and down the paths so please be aware and considerate!


Rhiwbach BAs

Hi All,

We really need to make a decision on the BAs in Rhiwbach if we want to purchase a batch with this years inspection reports fees to those who use Rhiwbach.
There are several options within the mine, and have been for a few months. We also need to decide how many to purchase. Its been suggested we retain at least 20 BAs in the mine. We could either purchase 10 this year and 10 next year (to stagger the cost and wear), or go all out for 20 this year.
We also need to decide on type. To help folk out I’ve added the options to the section on the Rhiwbach BAs to the mine inspection website. You can see the options at the bottom of the page here: https://northwalesmines.wordpress.com/rhiwbach-buoyancy-aids/
Could you ask staff to have a look and let us know by Friday this week?

Rhiwbach Steel works, part 2

Thanks to everyone who came along on Friday to shift the first wave of steel into the mine.

Around 2/3rds of the steel has been stacked by the bore-hole on floor 3, with the rest just within the entrance. We also removed one of the previously installed uprights (all will need to come out for the new structure to go in, although the plan is to re-use some of the steel from the earlier structure). It’d be worth passing this on to staff as if groups within the mine drop any of these stacked pieces of steel onto their toes it’ll certainly ruin their day!
The rest of the steel is due to be delivered on Thursday (18th Jan), again 10:30am at the Cwm carpark. We could really do with as many hands as possible that day to shift the steel into the mine. If anyone is available please do come along and lend a hand! 
Once the steel is in place the fun begins. The structure should be relatively easy to erect with it being bolted into place. Once up we’re going to need to pack stone above the structure to the meet the current roof, as well as along the sides. This is likely to be a lengthy process and we could do with a fair bit of help getting this sorted. At the moment we’re looking to make a start on Friday the 19th, so again if anyone is free please get in touch.

Rhiwbach Buoyancy Aids

We’ve introduced a periodic inspection regime for the BAs in Rhiwbach, with a log of the inspections held on a red clipboard in the mine.

Illustrations of the cover sheet, log pages (blank and following first entries) and numbered/marked BAs are here


Could staff using the mine please make sure any defective BAs are removed from the mine given there’s no secure “isolation” bin for any found to be damaged. Please also let us know if you do remove any BAs so we can make sure we keep enough in stock either through the contact us part of this site or through the email group. 

Here’s a video outlining the method used to float test a sample of the BAs. 2 older BAs were tested, both exceeded standard rated on the BA.

This system may well evolve based on feedback from users so feel free to get in touch if you think the system is not robust enough.
