Title: Spar Mine (Hendre)
Post by: Ian A on Apr 27, 2011, 04:01 PM
Location
SJ 188 677

Directions
Locate the Royal Oak Pub at Hendre and park nearby. There is a road behind the pub with a track running off to the right immediately. Take that track until you arrive at a small, derelict building and head up into the woods along a path. The shaft is a couple hundred yards up the hill.

Access
Permission is required from Lloyds Quarries

Suggested Equipment
None

Length
½ to 1 mile along all the passages

Flood risk
The bottom adit is habitually flooded with the water rising almost up to the level above on occasions.

Mine Attributes
Feldspar Mine. Numerous levels all laddered.

Description
A reasonable sized mine with (mostly) big, open passages on multiple levels.

Entering the mine by the main ladder takes you into the main system and you immediately find yourself in a big chamber. There is a level below here (connected by a ladder) leading to a backfilled adit, a waterlogged adit and also a hole to another level below.

Continuing along the first level adit you arrive at a small hole upwards where a fireman’s hose assisted scramble takes you to a shelf within a large, exposed hole (to the surface). Here a ladder can be taken down to another level and, again, another ladder to another level below.

In this level the passageway is it’s biggest with a small exit at the end leading to the base of the large hole which houses the shelf from earlier.

As series of three ladders takes you down to a further level with two parallel adits (one impassable due to a hole) which converge in a chamber with a passage running off to the right (only short) and a bridge directly in front with an upward sloping passage behind it which also goes blind.

There is another level below this level which can be accessed where the two parallel adits converge but the level below is always flooded. If the water depth is not to deep it is possible to swim into the adit but, usually, the level is above the ceiling of the adit below.

The mineral content of this mine is extremely rich with feldspar littering the ground and walls almost everywhere you travel.

Unexplored Passages
There are several passages known to be unexplored including a full exploration of the hole (which must be rigged) near to the base of the first set of ladders after entering the mine, the climb upwards in the chamber to the right of the bridge on the pen-ultimate level and other “holes” at the end of some of the adits which require rigging to pass or descend.

Digs
None Known

This is the main incline if you follow this it takes you to a steeper incline to surface but at the top its all caved in. Note the timbering to the left side to keep falling spar from the tracks.

Although they were found (and created) within a mine, the correct terminology is "cave pearl(s)".

I realise that this may be upsetting for your very sensitive demeanor but may I suggest you take the matter up with the people responsible for the English language (the Anglo-Saxons)- that is, if you can find any left alive :whistle:

Sadly, no, the spider did not come out - my photographic talents are not yet on par with my peers :S

Sorry you had nightmares but, on the positive side, there are far worse things to ponder over :silly:

Several questions....
I am puzzled by some of the pictures above as they seem to be taken in a different mine to the Hendre Spar mine I have now explored on several occasions.  

Is the level of water now falling at a slower rate?  It seems to me that the level dropped at about 10" a week when the water filled the whole lower chamber - a huge volume.  But now the water level just reaches the top of the incline, so in theory the water level should fall more rapidly if the rate of drainage volume is constant.  But the level of water in the incline does not seem to be going down much at all.

Has anyone measured the depth of the mine from the entrance hole down to the floor level of the lowest level now accessible?  Has anyone experimented with an altimeter to measure the depth of mines?

I am intrigued by the thick sticky texture of the clay like mud that now covers the lower level - as shown in one of the pictures above.  This is probably formed by the precipitation of very fine particles in the flood water. Has anyone explored the use of this sort of mud as a modelling pottery clay for firing?

Comments welcome...
Title: Re: Spar Mine (Hendre)
Post by: Ian A on Nov 18, 2011, 05:10 PM
My only comment is with regard to the receding water ....

We do not know why the water is dropping but have "guessed" something may have opened up allowing water to drain.

Assuming that is the case (and it may not be) the water may slow down it's rate of drain as it reaches the escape as the water pressure will fall or, it may become partly plugged with debris slowing it down.

It may not be a "Plug" in any event .....

Additionally, I am not certain the rate is slowing as, from Marty's pictures on facebook, the water has very clearly dropped significantly in the last two weeks (The deepest part where there "party" is stood is only ankle depth and Dylan was wading up to his waist there on my last trip 2/3 weeks ago.

[quote="JohnNicholson" post=3566]Has anyone experimented with an altimeter to measure the depth of mines?
[/quote]

yes, - but only the rather crude one thats built into my watch. Obvious potential problem being that in a system where the pressure variations caused by the cooling/warming of areas (i.e. anywhere where you have a draft meaning air moving from a higher pressure area to a lower pressure area) are going to influence the measurement. To add to this humidity changes also play a large part in the equation.

As can be seen from the relationship between p (measured atmospheric pressure) and h (the height in meters above sea level):


p = Po * ( 1- ( (L*h)/To ) ^ ( (g * M)/(R * L) )

Where:
Po = Standard Sea Level atmospheric pressure (101325 Pa)
L  = Temperature Lapse rate (0.0065 K/m)
To = Standard sea level temp (288.15 K)
g  = acceleration due to gravity 9.81 m/s^2
M  = Molar Mass of dry air (0.0289644 kg/mol)
R  = Universal Gas Constant 8.31447 J/(mol.K)


In large open mines - like this one - its much more likely to be accurate though :-) And lets face it, the degree of accuracy may/or might not been deemed good enough depending on what you're doing.

[/quote]

yes, - but only the rather crude one thats built into my watch. Obvious potential problem being that in a system where the pressure variations caused by the cooling/warming of areas (i.e. anywhere where you have a draft meaning air moving from a higher pressure area to a lower pressure area) are going to influence the measurement. To add to this humidity changes also play a large part in the equation.

Obviously all that is required normally is a dP i.e. the difference in absolute pressure measured at point x and point y within the mine, in order to give a height and providing there is no major changes in humidity or thermally induced pressure variations between these points then it should be pretty much bang on.

My reason for asking about the depth of Hendre Spar mine is because it seems to me that the distance we drop down through all the shafts by ropes and ladders is greater than the distance we climb up from the car park. In just want to get an idea of the level at which the mine was operated - and also how far into the mountain it extends.  It would all be answered by mapping.

If the water is draining out then it is probably not draining into the rive - because there is not a river.  It has already disappeared underground.  I assume that the river actually drains to Milwr.  So the water in Hendre Spar mine will also be finding its way to the Milwr.  How far down is that?  Are there known links from this area to Milwr?
Title: Re: Spar Mine (Hendre)
Post by: Ian A on Nov 19, 2011, 08:32 AM
The Milwr Tunnel is approx 440 feet below the road level and there is a link to it from Garreg Boeth which is only a field or two away from the Hendre Spar Mine.

I personally don't know the depth of the Spar mine but we have seen a further flooded incline (decline) with a divers line attached so there is yet more to see.

Someone, somewhere will have a plan of the mine system :)

Yes - there is a map (I assumed was drawn by Ian) at the beginning of this article, but now very out of date.  But it is a diagram in plan for each floor.  It would be interesting to see this mine in longitudinal section.

Post by: John Nicholson on Nov 21, 2011, 09:15 AM
That would be brilliant! It would be useful to have a reading at the car park and also at the place where the sheds are at the bottom of the incline.
There is a lot I still don't understand about this mine.  Why did the miners draw their spoils UP the underground inclines from low levels, instead of driving the levels horizontally to the surface?  Also where is the other part of the mine with an unflooded incline and a big chamber with machinery and a railway on a lower level?  Or is this a different Hendre Spar mine?
Title: Re: Spar Mine (Hendre)
Post by: Frank Hill on Nov 21, 2011, 01:38 PM
I think the incline you are speaking of is down the first ladder to a lower level then you have to go through a small hole and abseil (SRT out).
THis is the incline that I reckon connects somehow to the flooded passage Tim speaks of.
UNfortunately the incline disappears into a huge rockfall that would need a jcb to dig out (or some mad bugger!)
I'm going to try to check the depth at the bottom of the incline and compare it with the new bottom of the mine.
RE driving levels horizontally...IF you think about it they could'nt drive them horizontally as they would be permanently underground!
Title: Re: Spar Mine (Hendre)
Post by: John Nicholson on Nov 21, 2011, 03:23 PM
Permanently underground...
That's why I am so interested in the levels. It just feels to me that when we go down to the new lower unflooded floor, we must be lower than the outside - i.e. lower than the main road and remains of river.  But the incline we see disappearing into water goes even lower.  There is only one railway track so I assume the trolleys were winched up, and then again up to the floor above and then out somewhere.

How accurate is your meter?
Title: Hendre Spa mine. THE measurements
Post by: Frank Hill on Nov 23, 2011, 07:10 AM
Went to spa mine last night and took my altimeter.
Using the car park as a reference (altitude 0') here are the readings.

Sheds on path +40'
Entrance +130'
Bottom of firemans hose +130'!
Top of multi ladders & chain/rope section +120
Bottom of the latter +10
Bottom of mine where water has gone -40'

If you now move to the area that was originally permenently rigged for SRT.
At the small hole (leading to lower incline) +70'
Bottom of that abseil 0'
Bottom of steep incline -40'
Top of steep incline +40'

Conclusion.
I reckon that the bottom of the steep incline is the same track as we see in the section that has dried out (but still has some water in it). Although the bottom of this incline seems to carry on at a steep angle this does suggest that there may also be a lower level as suggested by the divers line.
THe blocked exit at  the top of the steep incline would actually come out at the same level as the sheds on the path.

RE: Water level.I also sopke to a chap who told me that the quarry behind the mine was pumping a considerable amount of water into the mine. THey have now stopped the pumping (he guessed about 8 months ago)so it could be that the mine has always been draining but at the same time being topped up by the quarry!

FInally he is convinced that there is a second entrance to the mine from the Cilcain end, he remembers mining going on there and said he reckons there may still be an entrance. If that is so where does it go as the lower tunnel certainly ends at the working face.
There seems to be some further working along that tunnel and through a small hole in the roof. I saw a ladder there and a bit of pipe as if someone had attempted to climb up.
Anyone know where it goes?
Meant to pace out the tunnel to get an idea how long but lost count!
Phew thats it!!!!!!!!!:)

Fantastic work! And a really interesting read.

I can't believe that I hadn't considered the possibility of the quarry pumping water into the mine. We had a similar situation in Oakley a few years back, but in reverse. They were pumping water out of their pit, having the effect of draining the lower levels of the abandoned mine.

There is another spar mine in Cilcain, but as far as I know it doesn't connect.

There are 4 Spar mines that I know of, three of which are in or very near Cilcain and they do not connect. :huh:

The length of the tunnel was paced out by Crazy John and I "think" he reckoned it to be 700m

Post by: John Nicholson on Nov 30, 2011, 02:15 PM
OOHH...  has Marty got a nice new face?

Hi Frank,
I am a bit puzzled by your measurement...

Sheds on path +40'  - OK
Entrance +130'   -  OK (but feels a lot more when you climb the slope)
Bottom of firemans hose +130'!  

I note the exclamation mark.  Does this mean that the route creeps slowly up hill and I did not notice this is happening?  So the top of the firemans hose could be higher than the entrance?

I assume the access to the other part of the mine is via the hole that I have always crossed with the railway tracks.  If anyone fell down that hole how far is the drop?  

How difficult would it be to fit new ladders to enable non-SRT people to get into this section?  If I could get a ladder, then how difficult would it be to get it into place?  Obviously a long ladder will not go through the doorway at the bottom of the first shaft,  but I seem to recall seeing another vertical hole with trees and daylight showing.  Is there a picture of Marty in this hole somewhere?

Another thought, if the water level is dropping because the operator of the quarry nearby has stopped pumping water into the mine, then is it known whether they hold a valid discharge licence to do so?  If they were to start pumping again then would this pose any danger to people standing in the lower chambers?  Is it known how the quarry connects to the mine?

THe exclamation mark is there as an exclamation mark and yes the firemans hose is higher that the entrance

Far enough to hurt yerself so be careful!

No chance of getting a solid ladder into it, probably get 2 electrons attached together but it would be awkward as they would be against a wall all the way.

Another thought, if the water level is dropping because the operator of the quarry nearby has stopped pumping water into the mine, then is it known whether they hold a valid discharge licence to do so?
Suggestion...don't get involved, questioning this in my opinion is dangerous. Its easy to stop access to the mine if you piss them off.
 If they were to start pumping again then would this pose any danger to people standing in the lower chambers?  Is it known how the quarry connects to the mine?[/quote]
I would assume that if they started puming whilst someone was in the mine then it would take a while to fill up. THe information i had was from a local person and the deduction about the stopping of the pumping and dropping water level is purely speculative.

reply to john think about were the road and river are, they are in a valley full of glacial drift it would not be cost effective also ludicrous to drive an incline here as you are 90 ft from the solid and flooding from a downpour would be a danger to the men and the pit props etc.
the main incline dips at the foot of the solid and is only at road level when you descend the entrance shaft followed by the next then asiel down the hole and down the icline for 30 ft total approx is 150 ft. the level before the absiel came out approx 15 ft up from the main incline which starts down at the top of the track there were 5 levels
in 1984 the furthest into the mountain was level 4 level 5 was driven in about 300 yards when the price of spar plunged  and there for the mine closed the last cars left in level 5 were the same as the one s in the limestone workings  miniture shovels
driven by air, i recall 2 at the face if they are still there the trucks were hauled up by winch was driven by electric motors when the loaded 1 came up the empty went down, ie as the top one got emptied the bottom one got filled, does that help.

We spotted what I believe to be the wormhole Morrisey went down in his report, I had a quick peek, but without SRT gear it'd be certain death on a stick so I thought I'd leave ith for now.

All in all we spent a good six hours underground, Walsh and CunningCorgi are great guys and the time flew. Had a great BBQ afterwards and now I'm feeling those six hours :D

Took a few photos on sub level 4 that I think are cool

Thanks Tim, I have been wondering about that. I'll read up now!

Yes, sorry - certain items of info are kept in a private area for members only where sensitive issues are being dealt with etc. We try to keep secrecy to a minimum but i know you'll understand what it means to go openly public with certain things.

I know about the need to keep certain things out of the public view all too well. I've got access to the private forums on a few sites, but I understand it takes time and contribution to build up the trust

It's worth mentioning that subs are £20 per year (non-profit making). You also need insurance (BCA) which you may already have. If you haven't we can sort it out for you and it is £17 per year (about double if you do it yourself). In both cases, it runs 1st Jan to 31st Dec. :)

Hi John,

I would love a lift to UCET meetings; unfortunately I'm the Birkenhead based lad of the four you bumped into yesterday before Poachers. :)

I'm study nursing BTW!
Title: Re: Spar Mine (Hendre)
Post by: John Nicholson on Nov 19, 2012, 10:50 AM
I am so glad you have managed to make contact with us through the UCET forum.
We had an amazing day yesterday meeting so many new cavers. Yourselves before and after our Poachers trip, and then in side Poachers main Boss Chamber we met three others who had filled the place with candles.

I think we may sometimes adopt your route to Poachers avoiding the steep hill walk.  But it does a lot to keep us fit and trimm.

Sorry I can't help with lifts from Birkenhead, as we come from Bangor.  I suggest you ask Ian or Mike Lehey if there are UCET members who come that way.  It may be that you could get a train towards Chester and Alison could meet you at Capenhurst or Shotton.

Post by: Andrew on Nov 19, 2012, 12:17 PM
Another of the motley crew you met the other day here.

I'm the one with short hair! :D

The other two will no doubt be along soon, we've been over to Wales before in the past splitting the costs of LPG as we go, no doubt we'll be back in the future for more mud related fun.

We had a mooch in Hendre after we left, although i'm not a huge fan of ladders so didn't spend an awful lot of time in there.

Hi Hawkeye - and others!
Very glad you have been able to post on the UCET site, and you are very welcome to join us for a weekend frolic underground.  I normally post a weekend trip most weekends, but next weekend I am doing a surveying course in South Wales, and the weekend after we have the UCET Christmas Bash.

I am sure we can sort out some way to accommodate overnight if necessary.  I can help if you are doing stuf near Bangor.

Did we also meet in Moel Fferna Slate Mine?

Hi John,

I've never been to Moel Fferna so it wouldn't have been me, one of the other three may have though - Xan?

Thought I'd add some Hendre pics, from another visit:

[quote="JohnNicholson" post=3764]

How difficult would it be to fit new ladders to enable non-SRT people to get into this section?  If I could get a ladder, then how difficult would it be to get it into place?  Obviously a long ladder will not go through the doorway at the bottom of the first shaft,  but I seem to recall seeing another vertical hole with trees and daylight showing.  
[/quote]

in my opinion - it would be easiest to rig the pitch with electron ladders and life line on a " per visit " basis

however if people REALLY  wanted a fixed ladder to enable anyone to access the lower level at any time - with no assistance the instalation is IMHO  the easy part

my first question is : i want to know who is going to pay for the materials

the next - the legal and liability issues of fitting such a ladder

i am going there tommorrow - and can take some measurements and think about the problem



the four opitions would be :

1 - a roy fellows template - cave exploration ladder [ 2 wooden drilled sides - with steel rungs ]

2 - a commercial pree-made alloy or steel ladder

3 a maypole ladder - as seen in the top ent of nagdolin

4 a all steel ladder - either pre built or assembled in situ

as john correctly opinies - the open shaft adjacent to the fire hose scramble does actually give access to the lower level - it slumps with mud / grit - but could be dug to increase access

but like i say at the top - who is going to pay ? - i will glady provide time effort and equipment - but cannot afford to pay for materials

its not just the ladder - it has to be secured [ brakets and anchors ] - and if an unsupervised ladder is fitted - the mousehole will require some protection too - like via ferrata foot holds ? to enable safe descent to the ladder itself


once a plan is approved - if the materials are transported to the site - getting them installed is the easy part

but there is the legal aspect - that must be addressed - and like i say - someone must pay for the shoppoing list

like i say - putting a fixed ladder in - opens up the lower level for anyone - but has a price tag - and legal implications

on trips featuring non SRT  capable folk - rigging electron ladder and lifeline is very simple - but adds to trip time

Post by: John Nicholson on Dec 28, 2012, 08:22 PM
Thanks for digging up this old topic Andy.
I have not been down the hole in question (down under the railway treacks), and it may well be that people do not want to see this section opened up to all and sundry.  For now it is an SRT only zone.  It will be very good to read your appraisal.

Also, we do not know whether this section is now also flooded, and not worth spending much extra effort on.

My, what wind we have to-night!

Post by: mike leahy on Dec 28, 2012, 08:41 PM
it would be quite simple to put a smal  platforf and a maypole in.
i will try and sort it out early in the new year

Are we talking about the route that people have refered to as 'The worm hole'?
Title: Hendre Spa mine. THE measurements
Post by: Danny Sutton on Dec 28, 2012, 08:48 PM
the area does not flood john, it is the next level down from here that floods, i've been down a few times.

as said, an electron and lifeline is the answer if people want to see down here, a couple of hangers bolting in would assist in the rigging.

i dont think it would be worth spending time putting in fixed ladders just to see the small area it would add to the mine, as unless the water level is going to drop again, it doesnt add much to the mine.

Post by: Andrew Farrow on Dec 29, 2012, 06:51 PM
please see the latest trip report from dan - the level was found to be flooded to a depth today -

instead of a fixed latter - maybe an inflatable boat should be put below the worm hole - so people can abseil into it - like at CRRT

Just been in tonight with the AN Thurdsday Nighters, and the water level is about as low as I've seen it, short of the level being explorable. It's pretty much ceiling level on the formerly accessible lower level. if it carries on dropping like last year, it may be accessible again soon.

I'll see if any of the pictures came out (Hand-held on the loose stuff, probably not).

No swimming last night as water level has risen quite a lot over the past few weeks.

Took a few pics of the ladders. Bit of a difference from my 1st ever underground photo when I first joined UCET 2 years ago.  :woohoo:

Post by: John Nicholson on Mar 06, 2015, 04:11 PM
Is that the current water level - just below the bottom ladder?
Has anyone checked the level of the water in the quarry above to see if it is also high when the Sparmine is most flooded?  Tim had a vision to by-pass the drainage from the quarry through Susan Shaft to a much lower stream way which could have the most desirable effect of lowering the Sparmine flooding so we can again reach the long bottom passage.

I thought that was the incline down to the water that we swam through to get to the bottom level
Title: Spar Mine (Hendre)
Post by: Ian A on Apr 29, 2019, 08:30 AM
Yes .... But .... it "IS" the bottom level. When you "swim" (around past where the camera man is stood) you are walking in the mine again. It's all on that level.

There is another incline underwater (decline?) which has a divers line attached. That goes to depth's untrodden.

 :dry:
Title: Spar Mine (Hendre)
Post by: Ian A on Apr 29, 2019, 12:28 PM
Erm,

It has been pointed out to me that the metal pipe does not go all the way to the bottom of the incline. Having thought about this (took a full second) I realised that to be correct. The photo is therefore taken half way down (giving the impression it is at the bottom!!!) meaning that the water is extremely high.

A visit to the lower workings cannot be undertaken unless you are a fish.

Sorry about that.
