Mine shaft woes at new Falmouth development
10:50am Wednesday 22nd February 2012 in Falmouth/Penryn

Mine shaft woes at new Falmouth development Experts have been called in at a new housing development in Falmouth after a mineshaft opened up in a garden – leaving one woman too scared to let her granddaughter move in.
The hole, measuring approximately ten feet by ten feet, appeared in the garden of an as yet unfinished property at the lower end of the Tremorvah Heights development off Swanpool Road.
It has already been fenced off and capped with concrete.

But on Monday exploratory digging was underway in search of a possible second shaft – under the watchful gaze of a mining specialist.
With work to assess the scale of the problem still ongoing, the extent of the mine workings remains unclear. It is understood that a number of investigatory trenches will be dug to assess their extent.

Developers Linden Homes say they are working to ensure that the safety of residents has not been “compromised” in any way and to “ensure all warranties are valid”.
A spokesman for the firm said: “A mineshaft has been uncovered in a garden at Tremorvah Heights. The shaft was not identified on the mining plans provided by a local specialist mining company prior to the development commencing. This is on the basis that the site has been investigated through several mining searches spanning the last six years.

“As a result of recent findings, Linden Homes has already engaged the services of another mining specialist to investigate the area and provide the necessary remediation requirements.
“Although all foundations have been inspected by an independent specialist consultant, we are now also working closely with the National Homes Building Council (NHBC) to ensure all warranties are valid and to ensure that the safety of our residents has not been compromised.”

However for one grandmother arranging an affordable home for her granddaughter through Coastline Housing, the reassurances given so far are not enough.
Cynthia Wood said she had been told by her solicitors not to proceed until more is known, despite claiming she had been told it would be fine and that it would still be possible to get a mortgage on the property later.
She said: “I’m terrified to put them in. They say it is at the other end of the site and that it would be put right if there is a problem, but I am not prepared to risk my family’s life.”

A spokesman for Coastline said that as the problem had only come to light in the past two weeks they were working with the developer to keep people informed.
The spokesman added that there was no pressure to complete on purchases until people feel fully reassured by the remediation works taking place on site.

Sara Cynddylan, sales and marketing manager at Coastline Housing, told the Packet: “The mining works discovered are on a separate part of the development site to those properties purchased by Coastline. All of these properties have been reserved and buyers are aware of the current situation.”
She added that Coastline Housing is committed to delivering affordable housing and is working in partnership with Linden Homes to resolve this matter to the satisfaction of everyone involved.

The Packet understands that some of the finished units at Tremorvah Heights are now occupied, but these are at the other end of the site to the suspected mine workings.

I've commented on the Overpopulation thread about the rash of new housing being built in Cornwall, which will no doubt turn up more cases like this. (But unknown mine shaft collapses are common here anyway - see earlier in this thread for examples.)
 
Underground ghost station explorers spook the security services

Legal battle over crackdown on friends found in disused Aldwych tube tunnel days before royal wedding

... Last month TfL (Transport for London) applied to issue anti-social behaviour orders which would not only stop them undertaking further expeditions and blogging about urban exploration but also prohibit them from carrying equipment that could be used for exploring after dark. Extraordinarily, it also stipulates they should not be allowed to speak to each other for the duration of the order – 10 years.
 
10 years? That's unbelievable. :(

They shouldn't have got caught then, should they? I don't think this lot did...

That site will be of interest to people who mentioned Detroit in the other thread around here somewhere. It is a little poncey, just atad pretentious, but you can't take it away from the guys there, they get around a bit.
 
It's only an application at the moment. It hasn't been imposed. Can't see it hsppening, well, that bit of it anyway.

Owners of Wentworth Woodhouse stately home make £100m insurance claim as building sinks into ground (but they only paid £1.5million for it)
By Daniel Miller
Last updated at 10:52 AM on 27th February 2012

The owners of one of the country's grandest stately homes are mounting a claim for more than £100m compensation, saying the building's fabric has been devastated by mining subsidence.
Grade 1-listed Wentworth Woodhouse, near Rotherham, has the longest country house facade in Europe. It boasts 365 rooms and covers an enormous area of over 2.5 acres.
The former seat of the Second Marquess of Rockingham, who was twice Prime Minister, and latterly the Earls Fitzwilliam, stands atop what was once one of Britain's richest coal seams.

Occupied by the military during the Second World War, the mansion - now 'in a sadly dilapidated state' but still surrounded by hundreds of acres of parkland - is currently the property of brothers, Paul, Marcus and Giles Newbold.
The Newbolds paid the relatively small amount £1.5m for the property in 1999.
They have now drawn up a £200 million Conservation Management Plan they say will secure the future of the building for generations.
The trio are seeking compensation 'likely to be in excess of £100m' from the Coal Authority, claiming mining works carried out in the area from the 19th Century until about 30 years ago have caused 'extensive subsidence damage' over the past decade.

However, the authority is disputing the brothers' claims and, at the Upper Tribunal, attempted to deliver a knock-out blow by arguing that 'damage notices' issued against it in February 2007 and August 2009 were invalid.
Nicholas Baatz QC, for the Coal Authority, claimed the notices were not worth the paper they were written on because they were issued in the name of Paul Newbold alone, rather than by all three brothers as freehold owners of the stately home since 2005.
The barrister also claimed the notices failed to give 'prescribed particulars' demanded by the strict terms of the Coal Mining Subsidence Act 1991.

However, ruling in favour of the Newbold brothers, tribunal judge, George Bartlett QC, said: "I conclude that the Authority's contention that the notices were invalid must fail...that is sufficient to dispose of the Authority's case".

The case will now go ahead for a full hearing, at which it will be up to the brothers to prove that the £100m-plus bill for 'remedial works' needed to restore Wentworth Woodhouse to its former glory can be laid at the door of the Coal Authority.

The Fitwilliam family owed much of its fortune to the coal beneath Wentworth Woodhouse. The area is honeycombed with deep mine shafts and, during the post-War period, much of the estate was used for open-cast mining, which came right up to the edge of the main lawn.

Some of these abandoned underground places look big enough that they could be converted into low cost housing. I'm a little surprised that the government doesn't consider this as a possible (partial) solution to the country's housing shortage...
 
I've always thought that about empty office space. I worked for several years in a building that have at least 7 floors totally empty, I always wondered why the company who owned the building didn't put in a few cheap little flats to get money back from the space?!
 
Some buildings can't be used for housing because of the original planning permission.
 
But properties can be re-purposed...there are plenty of factory lofts, churches, pubs etc. that get converted into living space.
 
I guess a building - like an office block which is still partly being used for work - can't be also used for housing. Shame tho...

Well...In my first job, I worked in a high street office block that also had a small flat at the back of the building. It was used by one of the long-term employees.
Then of course there are plenty of shops with flats above them.

It seems to me that where there's a will, there's a way - but unfortunately, the government doesn't seem to have much 'will'.
 
Oh yes, I didn't think of shops with flats.

Yeh I agree, I'm sure a lot of places could be made into half decent housing, it's such a waste when you see aboarded up place, let to rot.

Back OT, we lost a dog down a collapsed mine shaft in Cornwall many years ago. She managed to get out after a long, cold night down the open shaft. It's quite scarey to think that the ground could open up and swallow you!
 
There is a narrow gaugee railroad deep under London, it was used to carry mail. So it was called the Mailrail system.

It's been 'mothballed'(abandoned) for decades, there's a site on Wikipedia. It also appears in Charles Stross' novel of occult espionage "The Fuller Memorandum" wherein ;Bob Howard is transported across the city on the zombie operated Mailrail in pursuit of the errant document.

Chicago has a similar system used to deliver coal.

The mail system greatly resembled the small trains in amusement parks ans carnivals.

I just happened to be reading that article earlier, and it actually noted the mail rail was in use until May 2003, so it's been mothballed less than 10 years :) Also, some urbex people snuck in recently and observed that it's generally in pretty good condition just now.

It's also interesting that the London government and most people recommended continued use - only for the Royal Mail to shut it down anyway, siting it being cheaper to use theroad network. The evidence of this included them only using the railway at 1/3 capacity, implying they just wanted to make it look bad and wanted to shut it down in a more conspiratorial way :D
 
New Kinver Rock Houses addition to be revealed

A new rock house built within caves is to be unveiled later at a National Trust property in Staffordshire.
The Martindale Caves, an attraction at the Kinver Rock Houses, have been restored to show what life was like there during the 1930s.

Rock houses at the site were occupied from the 1770s to the 1960s and the new house will tell the story of the Reeves family who lived there until 1937.
The restoration took place following a National Trust consultation.
More visitors and members of public said they wanted to see the 1930s reflected in the caves, compared to other options of around the start of the 20th Century and the 1770s.
A family fun day will be held on Saturday from 11:00 to 16:00 GMT to celebrate the new attraction.

Last year, the Rock Houses had a record number of visitors, exceeding the 12,000 figure for the first time.
Custodian Mike Parker said: "The new house gives us a chance to tell more stories about the people who lived here and add another dimension to the visitor experience."

There's been a big pro-road transport position in the Royal Mail for 15 years or so. It takes no account of the knock-on costs to the community of increasing road transport when there are perfectly viable alternatives. No doubt its to do with eventual total privatisation of the service.
 
I was in error. The various rail systems I've looked into got a little mixed up in my mind.

I was astonished by the London Necropolis Line, a railroad built to service a cemetery. They had a skull and bones logo.

Read "The Ghost Map" city underground secrets are good morbid fun.
 
There was a big feature in the FT about the London Necropolis Line a few years back. Wonderful reading! :D
 
That might have been where Charlie Stross got the idea to use it in his novel, "The Fuller Memorandum".

Stross is very good at the Cthulhu/espionage genre-new, but a lot of fun-and he can write space opera, too.

Read his 'The Laundry' series! :imo:
 
An illustrated piece in the Guardian

All about the abandoned 70s project for an underground railway in the city centre. I had heard of the Arndale Void but this is the first picture I have seen.

Links on the page to other material about the relatively well-known Guardian Exchange (nothing to do with the paper!). Enjoy. :)

'Metal moles' begin work below London

Tunnelling work is about to begin on an grand scale in London as the £16bn Crossrail project gets set to build 26 miles (42km) of tunnels beneath the capital.

The first of eight highly-specialised Tunnel Boring Machines (TBM), which each weigh nearly 1,000 tonnes, is being positioned at Royal Oak in west London. From here it will begin its slow journey east, as it carves out a new east-west underground link. The scheme is currently the largest civil engineering project in Europe.
Described by Boris Johnson as "voracious worms nibbling their way under London", the 150-metre long machines will take three years to build a network of tunnels beneath the city's streets.

While tunnelling the TBMs will operate 24 hours a day and move through the earth at a rate of about 100m per week.
Each one is staffed by a 20-strong "tunnel gang" and comes with its own kitchen and toilet.
The machines are monitored from a surface control room which tracks their positions using GPS.
Hydraulic rams at the front keep the 980 tonne machines within milimetres of their designated routes.

A TBM will set you back about £10m. :shock:
Once their work is finished, the machines will be sold back to their German manufacturer Herrenknecht and refurbished for further use.

The TBMs will have to navigate London's existing subterranean infrastructure, including sewers, some 10 Tube lines and the Blackwall and Limehouse link road tunnels.
At the deepest point the machines will be travelling about 40m below ground.

The Crossrail scheme was first proposed in the mid 1970s, although plans to build full-size railways through central London were also drawn up after World War II.

When complete by 2018, the line will pass through 37 stations and run 73 miles (118km) from Maidenhead and Heathrow in the west, to Shenfield and Abbey Wood in the east.
The line is expected to carry about 200 million passengers per year and expand London's rail capacity by about 10%.

Unlike the Tube, the line's rolling stock will be the same size as mainline trains and some 1,500 passengers can be carried in each train at peak periods.

http://www.dailymail.co.uk/news/article ... uarry.html

A sprawling military bunker containing a treasure trove of vehicles and weaponry spanning more than two world wars has been discovered at a secret location deep within a French forest.
Like a giant time capsule, the huge installation, carved out of solid rock, is said to contain wartime relics from a German 77mm Model-1896 World War One cannon to military vehicles dating from the 1960s and 1970s.
It was discovered by a team which normally specialises in exploring urban areas. Although they will not reveal the exact location, it is believed the bunker once formed part of the Maginot line - the array of fortifications and defences constructed along France's borders with Italy and Germany after World War One.

Very peculiar that it is all in decent condition. Also odd that one of the investigators' face is pictured. Not usual of these type of things.
 
Thank you! A very interesting topic, and good information.

Mapping Britain's Underworld


Four million holes are dug every year in the UK. Five billion pounds are lost through the economic effects of disruption and traffic hold ups, while hitting a utility pipe or cable can prove fatal for those working on the road. Adam Hart- Davis reports on a major research project which is trying to solve the problems.

He takes us underground from his ancient ice house at the bottom of his Devon garden to report on Mapping the Underworld, the £3.5m programme involving universities throughout Britain. The aim is to improve how we locate the increasingly confusing and complex array of pipes, cables and sewers beneath our streets, and assess their condition - as well as ultimately providing a better map of what is beneath our cities to improve planning both above and below ground.

At the moment it's often difficult to know where such utilities are - an estimated one in four of all holes are dug in the wrong place. Maps may not be accurate because original records of where the pipes and cables are located often use reference points on the surface which have long since gone.

Existing sensors may have problems finding what is underground because of soil or weather conditions, while modern materials such as plastic or fibre optics pose a challenge to existing technologies.

Adam Hart-Davis tries out the prototype of a multi-sensor cart where four different sensors operate together to produce an all-in-one solution, so if one technology doesn't work well in certain conditions and with particular materials, another one will.

It is not an easy undertaking for the research teams or, as it turns out, for Adam testing the multi-sensor cart.

Can't see a Listen Again or podcast link, unfortunately.

I was watching them burying some utilities at the Hayle bridge works earlier today. Plastic tape is buried a few inches above each cable or waterpipe to warn future hole-diggers of what they're approaching.

The tapes obviously last some time, because there was some above the electric cable in the mystery hole I mentioned here
http://www.forteantimes.com/forum/viewt ... 963#925963
and AFAIK it's at least 19 years since there was any digging there.

As for positions of cables, etc, much of that is now linked to GPS rather than physical reference points. All well and good, until the apocalypse comes and we can't maintain the satellites any longer! :twisted:

Sometimes the excitement's more than I can bear...

But today the strangeness didn't happen till I got home and put the pics on the computer. I wanted to add keywords to an image of some workers burying an orange cable, marked by green tape, but on that image I couldn't read the writing on the tape. No problem, as I'd taken another, closer picture of the tape.

...but this other picture wasn't on the computer! :shock: I got a horrible feeling that I must have accidentally deleted it from the camera when I did my first check-through.

But I looked on the camera again, and there the pic was, with two others that had also not made it to the computer! That's never happened before, and I've taken over 1800 pics with this camera!

Anyhow, the green tape says (as I'm sure you're all gagging to know)
