In this film we explore the Ironstone Mines of North Yorkshire worked in the early 1920’s and abandoned decades later in the 1950’s
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially.

In the furthest drift among the roof props the 'work benches' are in fact heavy wooden supports for pulleys to direct haulage ropes. This drift went out to surface and was used to take a pair of ropes well inbye to a remote haulage plane. During the 1990s a couple of guys penetrated further into the workings wearing breathing apparatus but found progress eventually blocked by flooding.

Your alarm should always be set to 18.5%, anything below 18.5% is dangerous and can cause severe headaches, shortness of breath, anything below 16% can make your very unwell, anything below 14% can cause unconsciousness, and finally below 12% you are pretty much dead without rescue.

True story. I’ve been at 12% and it is a brutal punishment on your entire body…. In this mine too.

The three pipes laid in the return airway and travelling drift were: 1) the largest diameter for the outflow from the inbye pumps, 2) a compressed air pipe to take a air to operate at least one pump, the others probably electrically driven, and 3) a pipe bring fresh water to the mine buildings outbye from a borehole down from a supply on the surface. Monument Mine worked from 1908 to 1931 when hand-operated rotary drilling machines were used, not powered drills. See "Glimpses of Monument Mine Great Ayton 1908 -1931" by Richard pepper, published Peter Tuffs, 1996. Some of the steel joists supporting the roof are marked 'BARROW' having been supplied by that steel company, and a lot of the props on the main bank are made of concrete.

Wow thanks very much Simon for your detailed information ! 🙋🏻‍♂️🙏🏼😀

visiting there during high pressure weather systems makes a slight difference as it pushes the foul air further into the workings,

Excellent... Yet another Very Cool Mine Explore... 😃😎😉👍👍👍✌️👌🇬🇧🇬🇧🇬🇧

just passed where you rightly turned around is a large pully wheel, part of the endless haulage system, nicknamed the wheel of death, oxygen levels 14% regularly recorded there.

great video mate keep up the good work and greetings from Cornwall uk

@VikingExploration60 2 года назад

The pipes can be easily identified by the type of couplers, flanged pipe was always low pressure, which in most cases carried water, in this case the smaller pipe was probably a supply water to cool the drills at the head, the large pipes was probably a drainage pipe from a pump, at the work faces there would be a lot of water accumulation from the drills. The other pipe as a screwed coupler, these always carried compressed air.

@VikingExploration60 2 года назад

The drills would have been Holman Drills designed in Cornwall, the drill operates on compressed air and the drill bit is hollow and as water passing through it to the tip which cooled the drill bit and also helped to clear out the drillings from the hole.

Thanks for the Specifications Steve 😄🙋🏻‍♂️🙏🏼 that makes sense since one of the pipes was carrying water

Hi Antonio, this is a really good informative video because there are still some people that think they don't need an Oxygen meter. Thank you for sharing, much love. xx 💖

@@UndergroundExplorerUK I feel the need to say that you must calibrate your gasdectector before use (as like what is said in the manual of the thing - and it needs regular recalibration). Relying on that your meter and your mate's meter have the same reading... Good luck with that. Know your equipment... It is also not just an O2 meter. Measures hydrocarbons, H2S, CO/CO2. Gasdectector would be a more accurate term (sorry for nitpicking. But you should better inform your audience imho. You do not mention a gasdectector in your equipment video. A confined space is a confined space however you look at it. I refused once to go in one because of no gasdectector. They got another contractor. Three went in. Two came out). It would be interesting to mention some of the oxygen consuming processes - like in this case the exposed iron molecules turning to iron oxide. Can also be organic in nature (decomposing wood or what not), due to release of other gasses and so on.

the tunnel with the three pipes in ends in water, one of the pipes could be water management.

I want to take a moment and thank Antonio for introducing me to his RU-vid friends…they are all exemplary explorers.

the cable system is called a continuous loop, there would have been a cable on the floor which the tubs attached to and the return cable would be held up high to prevent drag which would create friction putting strain on the drive winch.

Hey pal the iron work you found at the beggining is known as a RSJ or Rolled Steel Joice, that's the traditional name, now I think its called H Section.

@BastardSquad 10 месяцев назад

This mine needs capping off; it’s lethal now. April 2023 - O2 levels down to 12%, and dropping. Not advisable to enter this mine at all..

@TheRopeAddict 2 года назад

Antonio and Curtis bent over *backwards and *frontwards to take me into this mine. I’m renaming this mine to The Lilliputian Mine. I’m very happy that you observed your oxygen monitor. I wonder what process is consuming the oxygen.

@UndergroundExplorerUK 2 года назад

Thanks Joseph !.. 🙋🏻‍♂️😄🙏🏼 I can only think that the oxidisation of the iron is consuming the oxigen !

@TheRopeAddict 2 года назад

@@UndergroundExplorerUK I agree it’s the iron.

@VikingExploration60 2 года назад

19.4% is also low, normal levels should be 20.3%

What oxygen meters use using?

También deberías llevar un autorrescatador MSA o FENZY, en caso de que no tengas oxígeno te puede salvar ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lcWDyq85t0I.html
