Thanks to everyone who came along on Friday to shift the first wave of steel into the mine.
Happy New Year All,
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.
Can all instructors please do their best to pick up any rubbish found on the paths to and from Rhiwbach, avoid toileting in obvious places (and pick up any toilet paper left behind), as well as stick to the main path leading down from the mine to avoid further erosion to the paths.
More info has been passed onto those buying into the scheme.
Following some recent observations and comments about the brow in Rhiwbach the GB team have been up to have another close look at the tell-tale paint marks.
There’s been the suggestion that small bits of the paint has been flaking off as it’s dried, rather than there been any movement in the main body of the brow. To try and resolve this the GB team re-painted the cracks and have provided the following photos.
Users may find it useful to print out a few of these photos so they can check for any changes.
I’ve just picked up a report of possible cracks in the paint marking the suspect rock in the roof of the boating chamber.
If you’re heading in can you let us know your thoughts.
Attached is a photo of the original painting.
