Payed a visit to the site tonight with my new telescopic infra red night time vision camera and the collapse is definitely a gunnis. The shaft plugs seem to be intact but the stoping could be connected to Dunkin's garden shaft, will know more tomorrow.

Came across the local nutter who was out lamping, he said that a number of rabbits were the main cause of the collapse especially one call Gus Honeybun who couldn't keep away from Dunkin's garden! Wink

Pengegon pixie, has the swing shovel cleared the surface cover?
That Gus Honeybun does have a lot to answer for!

Any sign of old collapsed timbering?
Meanwhile I am still keeping an eye on the slight depressions in the opposite (old sump) field! - Anyone fancy a late night jumping up and down session?

The nutter told me they have some sort of bridge for viewing from.I think they will have to assign a modern day I.K.Brunel to build a new one! IP: 86.129.228.174

If a stull has given way in stopeing then it might be big, but that is just guessing, keen to hear back from Cormac man!

Judging by the interview this morning, its sounds a case of fingers crossed at present, the interesting thing is going to be the strike length of the feature - for everyones sake (Particularly those living on Talveneth, which appears to be on the hanging wall at best) I hope there is quite a plunge on strike.

As far as I could tell, the width of the hole is about 4ft from rock to rock (right hole). This appears to dip about 20 degrees from vertical. The ground itself is a mixture of soil and backfill. The right part of the right hole looks smoothed in places, has timbers on the right in the fill suggesting to me it may have been an early passage through the stoping.

Clearly, main lode was pretty major at the top, perhaps this is a branch. According to my King of Plans chum, it is on the outcrop of main lode.

Somewhere, I have seen a section which shows a very shallow bit of stoping around there, pretty much to surface. I haven't run though it in relation to known shaft positions, but my guess is that it's there. I would have expected that the lode back workings were very ancient indeed, however those timbers, of which there were several in a line must have been newer.

Forget the holes which have opened up, the structure must continue under the adjacent buildings. Were they built with the bank saying "Mine Survey Please" or before?

I don't think there will be any spectacular mega-collapses 1km deep, or anything exciting to get into. I merely think that if they want to assure that all of it is "what happened there" proof, it might be more work than they think.

Keep an eye on it though.

this sounds like a candidate for a down-hole laser survey to properly define the scope of the problem.

Then 3 years of bickering about funding and liability avoidance with the householder(s) a very long way down the queue.....

The actual void sounds like a good candidate for the sort of staged backfill using foam concrete and accelerators that was done at Combe Down. Once you have a few metres of that below grass, what is underneath is a secondary issue.

Fortunately the council haven't got time to bicker, the new road is due to commence in March. Also they have pretty much admitted liability by spending a fortune remediating the site 15 years ago. IP: 90.221.39.42

Now we have a minor earthquake (or not?) to shake it up a bit more!

Allen Buckley and my good self did spend sometime over on the site with Cormac and someone who was involved in the capping back in 1992. Not that much had really changed from my first visit. A little more ground had run in making the surface opening larger and filling the void below.

I will be making more site visits when things are worth viewing.

As for local nutters, I was thinking some of them having been posting on here mentioning no names Laugh

To All,

Sorry for the delay i was not able to upload pictures to the site from my smartphone and have been out of the office!

I have managed to upload to my album but not direct to here? Any pointers as to how this works much appreciated!

From yesterday and todays excercise we can see that the void closet to the houses is an extremely old shaft. Evidence of stone walling can be seen in the pictures and also photo 3 shows where we think a kibble would have been raised?

Stoping is also evident as suggested but fairly narrow at approximately 1m in width. We have now commenced reducing the ground within the area to allow more reach with our excavating equipment.

Have a look in the album and let me know what you think!

Cheers
