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。

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。

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

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。

Thank you for showing some of the things that the stone was used to make! Very good quality video.

As always very interesting.

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。

even their rock quarries are clean and organized.

Thank you excellent documentary. Thank you for not putting music over the Video.

I always wondered about "Oya" Stone. Now I know....thanks.

令人大開眼界的影片！感謝！

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.

Cleanest active mine site I have ever seen.

Очень трудозатратный процесс, сколько должен стоить блок на выходе?

Amazing. What happens to the quarry when it is mined completely?

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?

What are they trying to get from the rock ??

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?

How old is this mine?

Không biết sau khi xẻ rồi mài bóng nó sẽ đẹp thế nào , chứ khi còn thô nhìn nó như be tông ấy ? I don't know how beautiful it will be after being cut and polished, but when it's still rough, it looks like concrete?

Saya mengagumi tingkat ketepatan dan kedisplinan orang-orang yang terlibat di sini. Mungkin penambangan batu adalah usaha yang ada di banyak negara, tapi pekerjaan pada tingkat ini saya baru melihatnya. Salut!

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.

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.

What measures are prepared in case of an earthquake? I don't see any reinforcements other than the concrete walls near the mine entrance.

@HanatakeYurii

Earthquakes are way less problematic underground. Sure cracks can happen and some weakened bits could fall off, but it couldn't shake as much as the 'thin' overground structures (buildings). The best you can do is watching over cracks and uncertain bits and reinforce them if needed. No way you can or should concrete the whole structure (would be way too expensive and overdoing it), rock is already hard enough given you leave enough matter for the 'pillars', it could only crack as would do non-reinforced concrete (thus why you should watch over cracks).
