Hidden Mineshafts on the hills

- In this video we investigate some hidden mineshaft's in the hills. These old mineshafts belong to the former Mine Tunshill colliery in Rochdale on the outskirts of Manchester and at the foot of the Pennine hills. The mine is now disused. But the old shafts are still in place. In this urbex we lower a camera into the old mineshaft. We used a go pro mounted onto a homemade device. Looking into the shaft we got a wonderful glimpse into the history of mining. The former Lancashire coal field was once a busy and productive coalfield in the Victorian era but now stands silent. As a bonus in this video we take a look at some old victorian architecture in the form of some underground hidden bunkers.
The miners son 'sounded' the roof when they noticed the trickle of water. They used to tap the rock/coal and could tell from the resonance of the tapping whether the rock/coal was sound. They had to listen carefully. There is an old geordie miners song which says, ' rap the bank me bonnie lads, hear that coal face working. there's many a marrer(mate) missin' lads because he woldn't listen.'
Similar to what the water board do when checking pipes with a stick ,not sure what its proper name is though .it checks for leaks by the sound .
Yeah I guessed it may have been that Tom
@@geoffdecorator1701 I think they call it "sounding". You can do it with big machinery, hear internal noises by using a long screwdriver, tip on the equipment (gearbox case for example) and handle of screwdriver to your cheekboneor near your ear. Carefull - it can be bloody loud. You can hear different noises like bearing whine, grinding, tapping etc all can indicate different faults if you know what you are listening to.
I've done it on diesel engine injectors to find the faulty one.
In mines, a dull sound, instead of an echoing sound, as you progress through an area indicates the sound is being absorbed by movement in the rockface - basically, loose rock, so a "dull" area is a dangerous area. You can make regular checks by clapping as you walk along.
Similar to 'wheel-tapping' on railway rolling stock I suppose?
@@stationsixtyseven67 Wheel tapping works on the resonance principle - a good wheel will ring like a bell, but a wheel with a crack in it sounds dull. So it's just like tapping the roof of a mine drift (tunnel) to see if has cracks/voids in it by the dull sound it makes
The straight face and info-graphic "I call it COC ROVER',,, priceless....
I believe something like 150,000 men women and children have lost their lives down coal mines in this country !. The wife and I have been down the Big Pit in Wales a couple of times, which gave us a tiny hint of the horrible conditions of the miners. Take my hat off to all of them ....Good video again. Happy and healthy new year to all.
Thanks Roger, Happy new year
I didn't know that place existed, I'll be booking my next holiday when this covid is over
Don't worry about having problems with your COC shaft. It's just one of the things you have to deal with as you get older.
😂😂😂
Seeing you 3 walking along the lane makes me think of. The last of the summer wine 😂
Lol or the Vic and Bob parody sketch 3 men in a bath lol....
Precisely what I thought; a few bars of the theme tune would have been perfect but, probably, very costly.
Which one is Compo eh?
100 years from now some urban explorer will be posting a video on TH-cam's successor showing how he discovered an ancient lighting device at the bottom of the shaft! 🙂
That will probably happen Ian
you always have to be careful dropping loose things down mineshafts in case Frank from the Exploring Abandoned Mines channel is down there.
@@gordslater spot on dude
Hi Martin. You should use Para cord or Mower pull start cord instead of rope. They are both braided, not twisted like rope and so won't spin. You would be able to make the whole contraption much smaller.
Happy New Year.
Thats interesting thanks
how about a string from both sides 2 lowering,no need to chuck it in,would need to practice.
@@lawrenceflanagan5037 Yes, I was going to suggest the same idea.
Victorians never gave old shafts much thought still collapsing in Stoke with 270 years of mining history. Try two ropes walk over from either side. Loved it when Fred Dibnah dug one in his back garden!!!
Yup they start with a ring the diameter of the shaft they want to sink and just dig it out and lay bricks around the ring and it sinks as the hole gets deeper. Simple yet ingenious!
Whereabouts in Stoke?

Absolutely fascinated by this, so much interesting stuff up north from our industrial past. Stay safe mate from essex
Thanks very much Paul
I'm proud to be British when it comes to discovering these long forgotten gems. Great find the storage cellar the walls were so flush and arch ceiling were perfectly rounded off. The scenery is beautiful also. Yeah great find 👍
Thanks, yes those cellars were very well built
@@MartinZero And the risks they took even at a very young age. Including the railways which are truly remarkable to look at. I live in Rugby I go down the Great Central Railway quite often. The platform is in very good condition. And as you approach Onley the view is beautiful to look at. See for miles. Anyway take care 🚂
Stonework is magnificent, another great video.
You need some kind of long handled prong, hook or grabbing tool to get hold of Coc Cam once it's back up. Got to be called Coc Grabber haha. Great video BTW 👍
Thank you
Try making a loop in another line several inches wide. Pass COCrover's line through it and walk the end of the looped line to the opposite side. You can then move it round a fair bit ;0)
@@totherarf easier to get a seat off an old swing, sit Danny on lower him down ( gently ) with a cable taped to head via old tennis swear band and pencil and sketch book.
@@craigja1667Fair point, well made!
Like a telescopic boat hook?
The stonework in those cellars looks fantastic - really well constructed...
Yeah they a bloody ancient as well
@@MartinZero Those corners are laser straight, absolutely amazing craftmanship thats stood the test of time and weather!.
@@MartinZero Don't you think that the stonework was too well built to be a simple storage area? I also noticed that the stone stairs showed little signs of wear so maybe they weren't used very much or if they were it was over a relatively short period of time. Intriguing to say the least. Fascinating video Martin, thanks.
Stone lasts forever. It doesn't crack or flake off.
As a bricklayer myself I had to compliment the quality of the stone and those nice sharp straight corners.
Enjoyable video 👍 loved the way you showed your respects to those poor souls who lost their lives. A number of years ago my partner went on a tour of a working mine Whitwick in Leicestershire just before it was shut down. It was something he will never forget and would never do again but has the utmost respect for those who have and those who do!
Yeah what a way to die Helen
video of the week for me seeing the binns and how well there built .
Yes amazing gem
Very very interesting part of local history. Love your videos and James smiling face
Thank you Marie
just a thought....
two or three ropes. 1 each side, also telescopic roach pole to hook the board over the hole., when back at the top, lower one rope and angle it thru the hole.
Yeah will do that next time cheers
Nice try though. Great work.
I was thinking the same. Would stop the spinning too.
@@bernardfender5147 Me too, but I am not that confident regarding the spinning. Might work well for the first couple of feet. But I also might be wrong.
@@schubser3327 hiya, two ropes, actually something like paracord would be even better as it isn't wrapped, attached at two ends of COC BOT(!) should stop spinning for quite a bit I reckon, if you keep the ropes apart anyway
Hi Martin, enjoyed your videos of Manchester history.
Being a Mancunian by birth it’s amazing how Manchester has changed since 1959
I have thoroughly enjoyed watching your exploring throughout the two lockdowns.
Superb videos😁👍 please keep them coming
3 ropes would make it easier to load into the hole and might help reduce spin, and a reverse view camera would give concept of depth. ;)
Cheers John
Next time mark the rope in meters or summat .. .. ..
Thanks Martin that was fantastic, those people that mined coal in those places were absolute heroes. What strange old places the little cellars were up in the moors, unbelievable really. Happy New Year. Take care and all the best. Stevie
Thanks Stevie, happy new year
Fantastic martin! The footage of the camera going down the shaft was amazing, it seemed never ending. Hope 2021 is a great year for team zero and your explorations. 🔴🟡🟢
Thanks Ruth, I wish we had seen the bottom
Loved the video, Martin.... Sheer escapism ..Very Wellcome too , in these turbulent times x
Keep up the good work. Love your informative videos especially the one's in and around Manchester and Rochdale areas.
HAPPY BIRTHDAY FOR TOMORROW MATE...... CHEERS :).... oh and happy new year Martin.
Thank you. You remembered 😃👍
Thanks for sharing that wonderful history!
I was waiting to see if there was a beam of light up into night sky after the light fell off,
Wonderful episode again.
I now have a certain Dead or Alive track playing in my head. ;)
Is it one of the 37 re mixes
@@MartinZero one of them.
The 96 remix.
NOoooooooooooooooooooooooooooooooooo stuck in my head now......Arghhhhhhhhh..............
Oh lord, please no. You realise it was the background music for a "shock site" (that also had *ahem* "COC" overtones), don't you?
Great achievement given the difficulties. The slowed down rotation gave it that Hubble telescope type view.
Happy New Year Martin and Team Zero.
Thanks very much Happy new year
Fascinating insights. A tribute to those that passed doing hard graft in horrific conditions. Thanks yet again for sharing, beats Eastenders hands down.
Anything beats eastenders.
Brilliant result Martin....!!
Hi Martin. Sod's law, I wrote a long comment on this last night and it doesn't appear to have posted! I shall try again, but with something shorter.
First off, for anyone thinking that they would like to try getting down yon hole, remember the gasses down there! They will kill you stone dead within minutes if any are present. The winter months are especially dangerous.
I am guessing that the entire hillside is very wet and that Tunshill pit would have been no exception, but I think that I can explain why you encountered no water down there. Lower down the hill is Butterworth Hall, the hamlet that you mention in the video, and there was once a mine there. Not all mine water is polluted and the water from this pit is pumped to a reservoir by United Utilities. You can visit the site and clearly see the concrete shafts, complete with access trapdoors, over the shafts. I remember thinking that the shafts were very close together. That is why, I presume, Tunshill is dry. It made sense to use a lower mines as a plug hole for ones higher up a hill. With clever engineering you could drain several shafts and many 'levels' from one point. I still wouldn't like to be down there in a thunderstorm!
Part of the site of the Butterworth Hall colliery has been taken over by an engineering firm. I can't remember the details because it was a few years ago that I visited, but I think that some of the colliery buildings are still there and in use. In the office reception they have some photographs, including one of the inside of the pumping house with the engine there.
Between Butterworth and Tunshill there was a railway of sorts. You can see it on old OS maps and the course can be clearly traced on Google Earth. About a third up the hill there will coking ovens.
If you want to explore more in the area, I think that the woods up against the west side of Ogden reservoir might be particularly interesting. There are numerous old shafts in the area, many of which are recorded as 'untreated', so I am guessing that they have the same minimal protection that you found at Tunshill. Unfortunately, no depth seems to have been recorded for many of the pits in the area, but they seem to have been about 3 metres in diameter.
This is fascinating, Brian 😮
Great vid, Martin, well done! Fish and chips with curry sauce! Good lad, James!
Yep I was torn between curry and gravy
Very interesting again Martin. Many thanks.
Thank you for another lovely video, I was brought up in Manchester so I know a lot of the places in your films.
Thanks Helen glad you enjoyed
Brilliant, as always, Martin.
Very “Heath Robinson”.
Thats the spirit of it Christine and thank you
Next time have another rope attached and take it around other side of the hole. This will help insert/extract it by centering over the hole with a second person handling the line over there. It will also help reduce spinning to a certain extent on the way down.
Much better would be to install a pulley on the crawler.Mmake it into a long triangular frame shape - look at a car trailer nose - the long smooth triangle frame shape will help clear obstacles on the way up and make it more stable on the way down. Mount the pully at the top of the triangle, where the trailer hitch would be.
You'll need at least a 3 or 4 inch pulley for best effect - smaller may snag. Make sure pulley is enclosed at either side (so you have to thread thread the rope around it by poking it through, making it impossible for the rope to come off the side and the crawler fall off)
A smaller diameter pulley will just drive you crazy - trust me.
This will reduce spinning further especially if it is a large pulley diameter. You could then tie far side rope off to a fencepost and lower/raise only from one side. You'd need twice the length of rope of course.
Regarding the depth - hard to tell with the light bouncing of the walls on the way down but a freefall drop of 1 second would be 5 metres, 2 seconds would be about 20 metres, 3 seconds about 45 metres, 4 second about 80 metres, 5 seconds about 125 metres.
Use the simplified formula 5 x (number of seconds, squared) eg: 8 seconds freefall drop, distance is 5 x 8x8 = 320metres
So, my guess is somewhere between 20 and 60 metres for your shaft when the light fell. seemed to be 4 seconds but it was bouncing off the side which slows the accelaration down a lot (coz of the 'squared' bit in the equation, innit)
Thanks Gord
@@MartinZero also, just like the triangular shape of a trailer hitch will help prevent snagging, any protrusions (light brackets, camera brackets) would benefit from having a long smooth triangle shape at the rear of them to prevent snagging. I suspect the light was caught on the lip of the shaft and got knocked off. If you had a triangular frame (just a bit of 1x1 or 1x2" wood will do) bolted on the upper side of the crawler rising up to the lamp backet, it would have just slip up the triangle rail and not got caught.
So rather than a simple flat, two-dimensional car trailer, think of a car trailer base with a horsebox mounted on it. What you want is an extra triangular rail from the hitch point (where the pulley is) to the top front of the pointy-tallest bit of the horsebox roof, so that, if you lowered a horsebox down a mineshaft, the roof of the horsebox wouldn't catch on the lip[ when you pull it back out.
Any other protrusions need a similar triangular rail to help slide and not get caught.
If you build this, test it by pulling it around the corners and angles of your house on the floor. If it snags on the door frames or walls, you need more triangular shapes to make it smooth to pull around the corners.
Flippin eck, shapes are hard to describe in TH-cam comments haha.
Brilliant! against the odds you did it! Thankyou for sharing!
Absolutely fantastic. Your footage and commentary was brilliant. Well done and thank you. You are very brave.
The footage from inside the shaft was stunning (and rather trippy). The workmanship must have been excellent for it to still be in such good condition.
I shudder now, thinking that as a kid I used to play on the site of an old mine in Oldham. Terrifying to consider that all that stood between us and a gruesome end might have been some rotten planks beneath a layer of sod.
That fish looked amazing haha! Great tunnel work! Hard place to get too!
Where you are munching your chips is near a historically significant site. It is where the Manchester Palls brigades were stationed prior to being shipped out to the trenches in WW1.
Hollinworth Lake was built to feed the canal at Summit (the highest lock in England) There is a visitors center there explaining it a bit. They even have the original sluice which was an innovative design!
Glad you returned to the sunny side of the hill safe and sound!
Cheers Dave
Great video Martin! Enjoyed watching that. Will meet up soon mate
Great video and some intresting hidden finds
Happy new year Martin. Another one of your great videos is a terrific way to start off.
Thanks Brian
Another great vid. Well done guys.
Thanks Xian
Great to see the return of COC Rover!
Given that men have been digging stuff out of the ground for centuries it makes me wonder just how many capped mineshafts there are out there. Perhaps that picturesque-looking hollow in a wood has rotting boards and a 50-foot drop below it. Not that I'm paranoid or anything!
This is my old stomping grounds. I lived in the shadow of tunshill. You should check out the kilns too.
The names of the miners who died are local names. My school teacher at Crossgates was a Mrs Schofield.
brilliant martin, theres something really interesting about brick lined mine shafts, that one looked deep. really interesting thanks martin, (and coc-rover)
Yeah anything mine related at the moment is fascinating to me
The return of COC Rover! Good to see it back in action.
Wow, very cool. I really liked those cellars.
Good werent they Carl
Wow incredible footage in the shaft. Can’t believe it’s just there with a wooden fence around that shaft!
Yeah great isnt it
Few things in life bring me more pleasure than seeing you carrying one of your custom made pieces of filming equipment to a location.
Another great video Martin!
My badly made custom filming devices 😃
Google Apple's first PC
Another great and interesting video!!!
Thank you Martin for nice video see you next week
Thanks Steffen
Great video, I left a thumb! Until the next video, thanks! Greetings from Germany
Yes yes yes another great video I love it when I get a notification saying Martin Zero has uploaded
What an abyss. These places really were hazardous. Tense stuff, Martin. Great telly, as usual. 🇯🇪
I really enjoyed the video Martin. I always watch your videos in their entirety but had to fast forward through the spinning footage.
Why Ray 😃
Right next to my estate this . I have found 4 shafts up there so far . They are soooooo deep . Thrown some rocks down some when I was young and they took ages to reach the bottom. The shafts are all over the reservoirs and lead up to the farms and over to hollingworth lake. Some shafts are on farmland so cant really be accessed.
Yeah there were a few mines up there
@@MartinZero if you go to one of the other ones they are boarded over and have hatches you can open to drop your go pro down.
As usual very fascinating. Happy new year Martin. X
Thanks Joan, Happy new Year
Awesome Martin. I cannot believe these places have not been filled in. So So dangerous
Dangerous but brilliant
Very good to see this 👍
Hi Martin great video amazing how those shafts have not been completely sealed with concrete slabs. Just to have a wooden fence is not the safest way to keep people out. I lived in Norden for 12 years and never new about the bins or their location
Cheers
Andy keep the faith 🐝 🐝
Thanks Martin lovely video, very sad about those young men dying down there what a way to go!, I was very impressed how well that shaft was built the brickwork looked still in very good condition
PS James seems to be coming out of his shell he seems more relaxed with the camera
Nice coc. Impressive shaft, bigger than I thought it would be.
I get that quite a lot
Valiant effort with COC rover :) , got some footage of the shaft and that wonderful stone work. Even the light boldly sacrificed itself for collecting data from the depths. Well done under the circumstances and materials at hand. That root cellar was just spectacular, the care in the stone work is haughtily beautiful. Drone shots really cinematic. Thank you for taking us there!
Thanks James, thats very nice of you, I appreciate your comment
This was amazing - I loved it! The brick lining on that shaft is incredible. I do hope you’ll be treating this as a Scout/rekkie exercise and will go back and do it again, I’d love to know what is at the bottom! As you said, incredible those shafts are still there like that. A lot of the mining history was very aggressively being completely obliterated at one time - I hope for the guys who were trying to protect it that things have now changed. This is the heritage of our ancestors 💕
Great work guys.
Thanks very much Jonathan
Martin, yet another brilliant video. Well done for taking the trouble to construct COC Rover. Just a little point Bowline is pronounced bowlin (Lin not Line). And if you tie ribbons every 10feet along the string, you can get an idea of the depth of the shaft.👍
Amazing 👍🏻 well done
Thanks David
Nice Video again! :) For that problem you had with the rover: Do a triangle of ropes on a board with a buttom mounted gopro and lights. then you just need 3 prople on each side of the hole to control the descent by giving rope as needed :)
You guys are great. Thank you
Thank you Mr Ginger Bread
Great stuff, thanks from Aussie.
Thank you 👍
That shaft was something elseee
Great to see COC-Rover MKll out of retirement,,, good effort lads.👍👍
Another amazing video guys 🖐️🙂
Thank you
A suggestion to stop the spinning would be a thin line attached to a corner of the framework controlled by a second person. It would also aid getting the frame in and out of any shaft being investigated. Hope this helps Martin.
Cheers Kevin
Great fun Martin!
You might have strung another tight rope perpendicular to your feed rope across from the fences and fed the coc rover vertically down directly over the centre of the shaft...
Thanks Bryan
Great video happy New Year Martin all the best for 2021keep the video rolling and keep safe 👍
Thank you Happy new year
Happy new year to you Martin and another great and interesting video 👍Great engineering too👍👍
Thanks Jay, yes fascinating find
Blimey.....that shaft.!!! I drove past Pule hill Marsden last week and there were people messing about climbing the fence that surrounds that water filled shaft u sent a go pro down a while back. Soooooo dangerous, bet they had no idea what they were next to. Back in summer i walked up there and took a few pics and dogs stayed well and truly on their leads and i kept my distance cos i had seen your video. 😮🐶🐶🐶
Oh that shaft, yeah thats another killer
Hey Martin. Amazing video and the masonry is just stunning. I've been to the Bodmin Moors once and that was also a verry stunning sight. Greetings from the Netherlands.
Fred dibna did a program in which he demonstrated how the ventilation shafts were built upside down bricklaying it was incredible I believe he sank a demo shafts at his museum in Bolton
happy new year to you martin james and john that was great very interesting and poor coc rover but you got in and out in the end we done for being safe all the best from trev and christine
Thank you from all of us Happy new year
Great video Martin, your passion for what you do shines through, please keep up the great work! PS. Check out TH-cam vids to improve your drone gimbal settings to improve the smoothness of your drone shots.
Hi Martin,
I could think of a few improvements to your camera rig. It would be easier to send down, easier to retrieve, and could eliminate the spin, but the biggest improvement would be to turn the board 90 degrees and mount the camera and lights across it, do away with the wheels and replace them with skids.
"Sounding" was just that. If you were to tap on the rock, you could tell from the sound, if there was water behind it. The trouble is, if you tap the rock, you can also bring the whole lot down on you.
"Inundation" is a sudden and catastrophic inrush of water. Typically an inrush from which there is little or no hope of stemming the flow, or recovering the workings.
Cheers 👍
We ,Capped few in Fife ,late 70s early 80s. Pretty dangerous, massive openings but very interesting. Black Damp gas, was a major hazard, especially in the side shafts.
Great video as always, thank you Martin. A small improvement to the COC might be to double up the wheels so that they stick out the furthest, shouldn't get stuck anymore when trying to get it in and out of the shaft. And as others have mentioned, pull the 2 ends of the rope towards left and right (with a mate), instead of tying into one rope, would probably stop the spinning :)
Cheers
Great footage Martin, I love this sort of mystery but sorry you lost your Lume Cube, I know how expensive they are. I hope you do a re-visit with a suitably modified rig up sometime, I'd love to see the bottom of that shaft. All the best for 2021 buddy. Just had a walk up to the Burdale tunnel but didn't go in, it's not far from me.
Cheers Stephen, Burdale was great
Scary hidden shafts, My God!!
Very scary Peter
Excellent! :)
Happy new year Martin and Co.... This spinning and the grating noise of the COC CAM made me feel like I was watching an episode of Dr Who in the 70`s.... Hehe! Well done though lads you had a good day!
Thanks Demelza 😃
Cheers from one Martin to another - my welcome bit of sentimental indulgence having left Manchester many years ago. Btw, you probably know that winters were much harsher there in the 19th C, where it always snowed between October and March. Imagine the place back then? I can see the significance of the cellars.
Yeah I bet it was very harsh Martin
Using 2 ropes would stop COC from spinning. You would have to have 2 people in order for it to work. Really enjoy all your videos.
Thanks Micheal
Another brilliant video I know Hollingworth Lake quite well as my mum only needs a few miles away
attaching a second line to COC Rover and lowering together would prevent spinning if another person was on the other side of any shaft with the other line, and if COC gets hung up on the edge, the other person could pull on their line to unhook it. Then you'd just need to mark the line with regular spacing so the two of you could lower/raise equally.
If the video could be streamed to another device, one can monitor the descent/ascent.
You could tie a short rope (say 3m) to one side of the COC Rover and tie the other end back to the main rope. Then you can lower/lift COC Rover end-on by pulling the short rope to navigate the narrow entrance. Alternatively, you could do something similar by moving the bowline knot further back (e.g. 3m) up the rope.
Just watched the video Martin, another top production from my fav TH-camr. Not sure I like the thought of curry with fish though lol.
Next time make It a Hollands meat pie with chips and mushy peas Instead.
With two people, one on each side, holding a rope across forms your "scaffold". A rope attached to one end of the trolley allows you to tilt it vertical. The center rope attached to the trolley runs over the "scaffold" and you have both ropes on a 3rd side of the enclosure.
Thank you 👍
The brickwork is amazing hello from Lightning Ridge Australia am an opal miner so I understood why you did not go inside that stone wall wise decision
Martin has a good sense of self=preservation lol A lot of people don't realise how deadly the gasses can be in a coal mine, especially in the winter. I don't know if you have the same problems in opal mines, but in an abandoned coal mine collapsing tunnels and shafts are the very least of your problems. Approach an abandoned coal mine in the wrong was and they might soon be carrying out your unmarked body from just a few yards in.
Incidentally, any chance of a few free samples from your mine? No harm in asking :-D
Martin and team - happy new year for a start, another great production. Also, what a great following you have all of whom sem to want to help problem solve, or add to the knowledge base! I might be repeating some helpful advice already posted but as a climber and general nuisance here are mine. If you can get to GoOutdoors or similar, buy a reel of 7mm climbing cord, it's good for over 1.3 tonnes static load, and doesn't twist. Mark it in 10 metre intervals. Learn to tie a figure of eight knot - much easier than a bowline, just as strong, and if tied wrong, it looks wrong. Looking forward to a great 2021 seen through your eyes and your camera. All the best!
Thanks Simon all the best to you
Oooh, you got a drone now? :) One for my channel being delivered next week :) Nice shots. We have had ariel shots before, but they've always been shot for us. Lmao at CocRover (tm), gave me a giggle! I was wondering how you were going to ride the side of the shaft when the hole is in the middle. There is a video on my channel where a professional rig is lowered 650 feet down one that is flooded, quite amazing to watch. that underground storage bit, not an ice house is it?
