Emptied and cleared all the bags that were en route or awaiting emptying and bagged up the old rotting ones for taking out of the cave later. I dug first, quite awkward digging now as having to dig around ankles with limited space around. Mike had a go next and then Mark and Stu – still plenty coming out, still have some sort of draught as the air remained clearer the entire time although really needs another bang.

Stu G turned up at Belfry with idea on breaking rock with air chisel, tested it and it used an entire 7L cylinder in 2 minutes! He hadn’t brought any kit, so didn’t come over. Henry on surface wall building still. Estelle, Mark and Mike to dig, moved bags up to Talus, then moved ones from shelf in dig to Talus leaving Mike filling bags. He filled 12 and we ran out of time. There is a draught, but no air as such, it is still quite hard to breath at times down there. Dig now has an archway going on at the end, floor still needs digging out. Reckon another session should let us know if we need to bang it again.

White Pit - 6/6/12 - back to the dig!

Estelle Sandford & Mark Denning
1.5hrs digging the end.
Mike failed to turn up on time, it was peeing with rain so we decided to give up the idea of cementing in favour for a dig at the end to clear the bang we laid back in Jan. Filled about a dozen bags until we ran out and then moved most of them up ready to haul and Mark carried on digging spoil out. The bang has done a good job and lots of fractured rock/stal, but reckon we’ll need another once we’ve cleared this. Sort of think we can hear space beyond, also at one point there did seem to be a draught, although the air was generally poor! We need to get this air tested for CO2 levels at some point soon… Looked at side opposite to the shoring on way in, we need to look at finding a way of making that safer as it looks like it has the potential to all come in and collapse rather than just slump and because of our new route in, we are caving more to the left now than before. We also need to have a damn good clearout in there as the place is minging with mouldy bags and other rotting vegetation we’ve left behind…

More wallbuilding and cementing. Mostly filled in the incoming side of Klingons, just working on the other side now. Both the left and right hand walls look like they have the potential to slump in without some sort of protection in place. They aren’t as bad as the main bit we’ve blocked off with metalwork and railway sleepers though. Reckon one more cementing session and we can go back to our dig.

Took over more sand and cement and made a mix then Henry arrived so we lowered the railway sleepers into place and put them on the metalwork. Then started wallbuilding on top of them and did quite a lot of cement before retiring to the Hunters.

Took down drill, etc. and generator to bolt some of the bars in place with anchor bolts, also removed a bit more rock to make sure we were back at secure rock. All three of the short lengths bolted into place, now need to bring down some cut down railway sleepers and cement lots or rock in. Mike & Henry brought some cement and Henry started a project to build a shed construction on the surface to house the air pump and generator while we are digging. They made a start on that.

Me and James at bottom loading bags/boulder net and rest at top hauling with winch and emptying said bags and net. All empty now so have moved the winch and a frame to under the trees. Removed a good pile of rocks, all make lovely rockery rocks!

Ivan had repaired the capstan winch (shit in the carburettor!) and back running fine. I had made a new boulder net for smaller stuff and we got to hauling lots out. Ran out of petrol part way but Ivan saved the day with some fuel he had as we’d forgotten and we reckoned at end of session we have about 1/2hr or so left of clearance. Got very cold on the surface hauling stuff out.

White Pit 3/3/12 hauling day

Estelle Sandford, James Begley, Stu Gardiner, Mark Denning, Trevor Hughes, Mike Moxon (fresh back from 6 weeks in New Zealand!). (Jo Hardy (& Amelia) and Hels Warren turned up with cakes and sausage sarnies lunchtime)

Turned up at Belfry and loaded up the capstan winch and scaff bars for A frame and all the other bits and bobs we thought we might need and headed over to the dig. Stu missed the obvious chain over gate post when trying to get into the field, but thankfully I noticed that one! We initially tried to ‘sled’ the winch over but decided to wheel it across as field not that muddy. Set everything up and Trev soon arrived with boulder net and some strops. We set to work with me, James and Stu at the bottom and Mark and Trev at the top who were joined by Mike an hour or so later with his jetlag! We removed roughly a third of the pile of boulders before lunch and I also went down to the dig to see if I could get a suitable skip, but we seem to have only damaged ones. The dig was clear of fumes, although very mouldy and there is plenty to clear at the end now from the last bang we couldn’t get to a couple of months back! Came out at 1ish when Jo turned up for lunch and beers and then Hels turned up with cupcakes. We went back underground/surface haul soon after, but the winch only lasted about 30mins or so before it started stalling on us and we couldn’t keep it running, so forced to give up and go and drink coffee at the Belfry. Hoping Ivan can fix before Wednesday so we can continue clearance and also get on with the shoring work. When I looked from the other side of the collapse, there’s a boulder that looks a bit dodgy, but it may be possible to force it to stay in place with shoring/cement.

Templeton 22/2/12

Mark Denning & Estelle Sandford went over to Templeton to collect some steel for White Pit and have a look at their dig and dig with them. Stu Gardiner came over and took some metalwork, but didn’t go underground as he didn’t have kit.
They have some serious engineering there, including a dumper truck and cctv and lots of winches and pumps! They also had a breakthrough on Monday into a new pitch which is 35ft long and 8-10ft wide and still going. Mark went down to look at that and I went down to their main dig which had just finished being pumped out. Dug about 10 or so buckets and then came up all the fixed ladders to the surface. Very muddy at the bottom.

Using the trusty chisel and ‘feather’ method – lots of holes drilled and used them like plug and feathers to break up the boulders, many fractured easily with just sledge hammer. We have cleared all the boulders now from the top of coffee pot and that is now open, and can get through to Talus, although still looking dodgy – I went through to have a bit of a look and don’t think it’s likely to come in on it’s own again, but we need to shore it properly having started the job! Waist of Thyme is now blocked with the spoil requiring going to the surface. We are planning to sort a weekend job of hauling and clearing with borrowing an A-frame and winch to do the job. Also needing to go over to Templeton to acquire some metalwork as they have all the digging pile of steel donated by Trevor Hughes.

Others came down to assess the damage and give us ideas on way forward with shoring. We removed about 2 tonne of rock from the collapse up to the entrance to Waist of Thyme and nearly blocking the way on there. 20 bags of spoil as well and all this needs to go surface once we’ve sorted out a winch/A-frame. Way on is sort of open, but needs a lot or rebar and shoring up and cementing in order to stop further slumps.

White Pit 1/2/12 - crash... bang... whallop...!

Estelle Sandford, Stu Gardiner, Mark Denning
1hr
Took a longer bar and hammer down, poked the armchair sized boulder and the wedge and didn’t come down immediately, but putting a rope around the little one and prodding the big one brought the lot down – an immense amount crashed down making Stu literally leap up out of the pot and we all exited pretty fast as it felt like the cave was caving in! Went to surface and looked around, it hasn’t collapsed the surface! Went back down and took a closer look, can still hear rocks falling and the way on to Talus is thoroughly blocked now. We need to consider whether to try and access from above or try and clear and cement this in to regain access in coming months.

Went to look at dig at end of talus and still really bad with bang fumes 1.5 weeks later. It had been noticed when they went down on the banging trip that there had been a slip at the dodgy place by top of coffee pot/Talus junction so we took a crow bar and some rope and realigned some boulders – with a little prod and pull, we had serious boulder jenga and loads came down. Coffee Pot is almost blocked now and the way on to Talus is still just about passable, but there is a hanging death armchair sized boulder ‘floating’ above so we won’t be going under there in a hurry. Decided to leave it to self dig if it wanted to and come back for another look later.
