Title: Old Holloway Vein
Post by: Robin Jones on Nov 14, 2020, 11:07 AM
Here is some info on the Old Holloway Vein:

The Western workings of the vein were drained by the Gorsedd Level which, travelling North becomes The Tre Eden Owen Day Level.  The connection with the Gorsedd level is via a branch vein 37 yards north of the Old Holloway Vein (Which I assume is directly North from the Coetia Eithin Shaft (now lost due to modern house with extensive grounds)

The vein travelled West and terminates appoximately below Lloc Chapel and travels East as far as Pant.

Here is an overlay I've done detailing the features:

I don't think so, when digging in the shaft Thursday evening John had to come out when water started gushing out from the mine faster than we could pump it away, I think this could mean we are close to the end of the silt.

If you funnel a 2 mile mine's worth of water into a 1/4" hose pipe and put your thumb over the end (your thumb being the restriction / silt in the mine),  When you release your thumb, you will see a full bore of water coming out of the hose due to the 'head' of water that has built up   Eventually, the head of water will reduce and the local water table will find it's 'organic' level.  Let's see what happens.  I'm cautiously opomistic about this dig to be honest. There is no reason to suggest we won't enter into 'walk in' passage any day soon  :)

I wouldn't waste my Thursday nights if I didn't think it was a goer. I abandoned my Bryn Celyn dig for this one.  ;)

This is true of every dig in th ewhole UK. There is no greater optimism than that of cave diggers, however, sometimes* thay are right...

*although not that often

great we could do with it as we intend to install the 6 inch pipe and try to flush the silt out of the northern end which will allow the silt to flow down from the southern end. :woohoo:

I have some good news Doug your level has a rise of 1 ft per every 100 yrds so if you have a 6 in headroom above the gravel at the dig it will get bigger as you go further if its not silted to the roof at the dig it cannot be silted further on. Mick

There were several reasons, but there is no point going into them and picking scabs all over again  :lol:

No in a word. If you're running early for a milwr trip, it's worth poking your head in though. Plenty of hanging death in there though so make sure you make a will before going  :sick:
