Longest UK dig?

Pie Muncher said:
OK, my omission, should maybe have said longest continuous dig. If you no longer have to dig to get on, it's not a dig anymore :shrug: If the way on is blocked or you can't get through, it's a dig, yes?

I'd agree with that.... A dig needs a face, or a bottom. I suppose you could work by project in a complex system. I reckon open passage between dig faces in the same project constitute part of the dig

Digging the opposite way from the breakthrough window continued horizontally a short way and then down (in the hope of finding the other side of the Western passage choke). This is the 35m vertical that Dave Webb mentions in my link (I'd need this distance confirming though).
I think this can be considered a continuously dug vertical range.

Hmm, "vertical"??

This is hard work, has anyone got a sketch or survey of the internal shaft dig at Titan please?

...continued horizontally a short way and then down

Down for a vertical range of 35m I believe.

Next time you do Titan:
1) go down the entrance shaft (concrete/fibre glass rings etc.)
2) Identify the passage to the breakthrough window into the main natural Titan shaft.
3) Turn around and go the opposite way from this
4) If your eyes are closed, you will shortly fall down a dug and shored shaft.
 
The current dig in Perforation Choke in Bone Hole (Mendip) has been dug for something over 100m length (40m vertical range) in a single boulder choke.  We have had the odd small void in that distance, but it is shored and dug for the entire length of the dig.  It currently takes about 30 minutes of caving in the choke to reach the dig face, and it has taken very nearly 4 years fo effort so far...
 
Grace's Lane always seemed like the 'finders' had dug a long way down - but I guess it's only 30m before breaking into the first chamber. More digging then to get into the rest.

How much of hte Pollnagollum - PoulElva connection was dug? I know some of it was. That's quite a long tube.

Not much. The original explorers could see each other through the impassable bit. According to Tratman* only about 10 ft was actually dug out.


*The Caves of North-West Clare p 22.
 
I've no access to figures at present, but guess Wind Tunnel/Colostomy and/or Trenches in Peak/Speedwell might be a contender.
How big was "big dig" in Nickergrove?
 
N.W. Inlet dig in Craig A Ffynnon. 70 metres of railway here. One of the most impressive efforts at least.

You have to sneak past the dragon too.
