They don't. Have a look at 6:00 they put a wedge in the cut groove. Pushing that deeper in will angle the stone creating tensile stress at the end of the cut which will at some point create a crack. The stone's strength under tensile stress isn't that high so it brakes at the end of the cut and the induced crack runs through. You can see, that the break plane isn't smooth at all. The crack just extends along the stones structure. The crack propagation for brittle materials is usually instable, there is nothing in the material that keeps a once developed crack from propagating under stress. This is why a porcelain coffe mug shatters dropped to the floor, while a metal one gets a dent.
When cutting the stones, lots of -sand- is being generated. What are they doing with that? Hope not dumping it somewhere? One could add some sort of binder, cement or glue or the likes. And press - manufactured grade - Stone plates. For driveways? or gardens?
Looks like a Mine Craft excavation. I'm sure this could be automated far better. Seems to tie up people doing mindless task for much of the time. Could be a useful hole when completed. Nuclear bunker perhaps.
would that have been -tuffstone-, millions of years ago formed on the seabed, with millions of little dead creatures, sand, clay, heat and pressure? European old Churches or buildings were built with that kind of stone. Still very hard, but fairly easy to cut and work with?
You can cut huge blocks of various types of stones like marble just by using ropes coated in abrasives. They can probably cut things about 3-4 times as fast by installing a water cooling system and using faster self-sharpening chainsaw blades with a smaller diameter.
@@provo-go7717 Nah, they sometimes used abrasive coated ropes in ancient times to cut the last bit of big chunks they couldn't reach with more traditional tools. Nowadays companies use chains coated with diamond abrasives.
What a bizarre place? My grandfather work in coal mining in the north east of England you can bet the mines he went down didn't look like this! They were hellish places.
I was expecting a lot more complexity for a device that big and bulky, like a dust collection bin or a water jet to make guide cuts but i guess it must be ancient.
栃木県宇都宮市生まれ育ちです。実家が石材業だったのもあり、大谷石の掘削作業やらを見学した記憶もあります。私にとってとても懐かしい、そして今も続く長い伝統。
大谷石は大谷地区だけでなく、掘れば多分中心市街地からも出て来ます。
جهد كبير من رجال مخلصين الف تحية لكم من العراق بلاد مابين النهرين بلد الحضارة التي اهلكته الحروب اتمنى ان نكون يوما مثلكم ❤❤❤❤
素晴らしい動画でした。
観光エリアは行きましたが稼働エリアの見学も可能だとは知らず、こちらも興味がそそられますね。
現地のスケールは映像で見るのと自分の目で見るのでは全く違いますし、坑内の独特な冷気や壁面に見る掘削痕の独特な模様は古代遺跡の壁画の様でした。
また訪れたいスポットですね。
県左官組合の研修旅行で連れてってもらった事があります。
真夏なのに穴の中はめっちゃ寒かった記憶がある。
そして見た事がない世界。
広さにビビった。
Thank you excellent documentary. Thank you for not putting music over the Video.
BISOUS BONJOUR DE LA FRANCE BIENVENUE JAI ADORER JADORE CONTINUER MERCI A BIENTOT
Cleanest active mine site I have ever seen.
貴重な良い映像。現場も理路整然としててきれいで素晴らしい。
昔はカイジの地下労働みたいな感じだったかもしれないけどｗ
記念館で一般開放されているエリアとは別で、この撮影がされている現在掘っているエリアに入ったことがあります。
下に降りる階段が木で作られていて、地下水で滑りそうになりながら慎重に下りて行ったのが良い思い出です。
震災から1年ちょっと経った後に1度だけ事前申し込みを見かけて参加しましたが、今でもやってるのかな・・・？
見学は受付けているか知りませんが、概要欄には現在も稼働中と書いてありますね。
大谷石で出来た蔵が庭にあったな。
栃木は大谷石の塀とか多い。
even their rock quarries are clean and organized.
8:22 very fascinating stairs!
もう10年､いや15年以上前になるか､大谷資料館で公開している昔の石切り場なら見てきたことがあるけど､
たしかにこんなかんじの壁の模様があったなぁと思い出した
あの模様はこうやって定尺での切り出しを繰り返すことで生まれるんですね
i enjoyed the end part where you showed how used, very interesting.
As always very interesting.
御安全に。
今でも採掘してるんですね👍
فعلا الذي أسماكم كوكب اليابان صدق ... تحفه وفن وابداع ... إلى الامام اليابان الجميلة ....
Thank you for showing some of the things that the stone was used to make! Very good quality video.
@ 6:50 using feathers and wedges to crack a block free.

Knp ga pke semen ya
Очень трудозатратный процесс, сколько должен стоить блок на выходе?
Adding wheels to bin for kerf waste could save many steps walking with the full shovel
They have plenty of time during the operation
中に鉄骨組んであるのがすごい
6:15
これって安全靴とかじゃなくて普通のゴム長...？
足に落としたらヤバそう...
防塵マスクとか機械の歯のガードとかも無いの危なくないのかな
あはは😂、ペリカな世界だから必要ないんだよ。
流石に安全長靴だと思いたい
This stuff rocks.
It is always a problem to take out the first piece of sugar from a box. How do they cut out the first stone?
凄いな
まるで地底遺跡だ
Người Nhật họ khai thác rất chuyên nghiệp, kỹ thuật,an toàn, sạch sẽ, tiết kiệm tài nguyên.

What do they need palace for ?

Stupid question ! Is there anything more luxurious than a palace to live in?
ありがとうございます
Steve makes it look so easy.

令人大開眼界的影片！感謝！
That's the cleanest mine I've ever seen.
All those wire harnesses are putting in WORK!!!
凄い吊り方しますね。。。自分はとても真似できないです。。。
ご安全に！
Ol' plugs and feathers still work just as well as they have since antiquity! Wedges are a marvelous thing. :)
The acoustics in this area are really interesting... I would love to see a longer cut that showcases the sounds.
와!현장 깔끔한거 정말 인상적이다.
Anche in Italia,a Carrara ,è così per l'estrazione del marmo bianco,che ha onorato ed onora sempre l'Italia per i magnifici lavori scultorei realizzati con questo pregiato marmo dal colore della purezza...
Fanno impressione le dimensioni e l'organizzazione di mezzi e uomini all'interno del sito di estrazione.
Davvero impressionante.
日本はすごい！
would be great filming location...like a villain lair or something :)
Systém co funguje i pod zemí, ten kámen stále kvalitní, jeden způsob těžby, čekám jak kámen uplatní a vzhled❤
Super! Merci du partage! Stéph.
Great video
Великолепбно снятый производственный процесс👍👍👍
Добыча - это не производство.
Wow, this is amazing.
The cranes are amazing...
A disturbing lack of respirators. Is the dust not hazardous?
It's wet down there
@@sydneyshinshi And yet you can clearly see dust and them using silly cloth masks over just the mouth, Even if the is no quarts it can't be good to breath, The same things shocked me just after Fukushima happened.
@@That1ufo Yeah you are probably right mate. There is plenty of evidence of the heath damage of airborne dust I suppose. Cheers from Oz.
The stone itself looks like a concrete block🤔
Amazing. What happens to the quarry when it is mined completely?
A big flooded cave 😄
テレビヒーローの遊び場か地下の観光地
They use all the accumulated dust to make geopolymer blocks, then make pyramids, its been done before.
ハンマーの響く音が心地よいですね。
Tenemos muchas metas 💪 🙌 ✨ x cumplir animo
That's fantastic! It looks like volcanic ash?
Near me in Englands Lake District they mine slate in a similar way and it gets turned into many products too.
Ben bunu ilk kez görüyorum cok güzel ben mermer silimcisiyim cok beyendim
近いうちに孫娘に大谷を見ようと思案中です
Japonlara bu taş ustalıklarına hayranım inanınki türkiyede böyle işyapan yok malesef deyerine bilenyok
great video man, thank you
This is unlike any underground mine I’ve ever seen. It’s just so, orderly…
Astonishing work
And what will be built in the excavation?
そして、発掘調査で何が建てられますか?
The played out sections will be used for storing stuf that need a stable climat/temp.
I always wondered about "Oya" Stone. Now I know....thanks.
Цікаве відео получилось, дякую)))
Неужели блоки из бетона дороже выходят?
What they do with this stones?
Lugar bem estruturado, os funcionários são ágeis e precisos, trabalho q requer bastante atenção. Muito interessante!
what kind of stone is this?
How do you cut under the stone to remove them
They don't. Have a look at 6:00 they put a wedge in the cut groove. Pushing that deeper in will angle the stone creating tensile stress at the end of the cut which will at some point create a crack. The stone's strength under tensile stress isn't that high so it brakes at the end of the cut and the induced crack runs through. You can see, that the break plane isn't smooth at all. The crack just extends along the stones structure. The crack propagation for brittle materials is usually instable, there is nothing in the material that keeps a once developed crack from propagating under stress. This is why a porcelain coffe mug shatters dropped to the floor, while a metal one gets a dent.
I wonder why this quarry is underground. Are there not areas where the stone is closer to the surface?
Qué usos especiales tiene esta piedra?
How big is that mine? Looks quite cavernous .
Dangerous and hard work, using cast concrete is a better idea
Yes it is silly to use stone. There is a global shortage of the stuff
cant they afford a second shovel 😅 i wonder why they go with the chain saw over a circular saw?
Wah hebat
Not a real pretty stone like marble, do they polish it up?
まるでコンクリート打ちっぱなしかと思える壁、これ全部上から切り出していった結果かぁ…
地上はクーラーがないと生きていけないような暑さなので夏も冬もある程度気温が一定に保たれる地下がうらやましい
不錯的材料，製作非常精實

You do a hard and good job💥💥
Greetings to you from Egypt 💥💥
this feels like aperture science vaults :D
This is fantastic. Hardworking guys , all well planed and simple method
That is some seriously soft stone!
would that have been -tuffstone-, millions of years ago formed on the seabed, with millions of little dead creatures, sand, clay, heat and pressure?
European old Churches or buildings were built with that kind of stone.
Still very hard, but fairly easy to cut and work with?
What are they trying to get from the rock ??
Mi pregunta ❓ y para que son ésas piedras o esos bloques alguien que me diga gracias
Wow, Minecraft in real. How Long they are diggin in the ground to get These big Caves
Minecraft at its finest 😄
Ese material producto del corte es Cemento Blanco , que se puede rehutilizar en la construccion.
saludos perfecto para que sirve ese tipo de mineral y por que le llaman de olla
تحياتي لكم من المغرب
Multumesc pentru impartasirea acestui proces tehnologic!
와우 작업장 관리 최고네요
I was very surprised at how fast the cutting is. Good chains.

@@Runefrag if by ropes you mean steel ropes then yea, but normal ropes would be torn apart by the abrasive faster than the stone would
@@provo-go7717 Nah, they sometimes used abrasive coated ropes in ancient times to cut the last bit of big chunks they couldn't reach with more traditional tools.

Looks like a Portal level to me. I especially like the ladder to stair combination.
