Videos of researchers who visited the catacombs, quarries in the Crimea. And analysis of information from these videos.

The reader shared the videos: Prehistoric traces of high-tech stone processing

We watch from the 5th minute. Comments below … These tracks are especially interesting:

Image
Image

How were they left behind? And by what technology?

Image
Image

Footprints on the ceiling

Image
Image

In this place of development, too, the same traces

Image
Image

The traces left by the cutter. There are some layers on the walls

Image
Image

The cutter height was about 25 cm

Also traces from the cutter

Image

Cutter height about 32cm

Ceiling For example, here are the types of modern limestone workings:

Image
Image
Image
Image

Sawed down the rock with a chain saw (wide traces are visible)

Image
Image

They did it with about such a saw, although for cutting limestone there could be a saw in an easier way. See below

Wall surface with modern workings

The width of the cuts is 25mm It is possible that this was done with this installation:

Here is a stone cutting machine in the face. You can see the tracks as in the last video, but they do not look like the tracks from the first videos.

Cutting lime blocks in the quarry. As you can see, in our time there are huge hydraulic mobile saws And now let's return to the first screenshots made from the video, which shows the traces of the cutter on the walls. It turns out that it was done like this:

Image
Image

The process of sawing shell rock. All the same arcuate grooves remain (from a circular saw). A source

Image
Image

There are also horizontal stripes on the wall

Inclined stripes on the wall in the foreground

Image
Image

The process itself, and with automatic feeding of cut blocks. The installation looks very simple.

Here is an underground mine working with similar equipment. But this video does not explain the marks on the ceiling of the faces from the first videos. They are not at all like the marks from this modern saw. In addition, there are old photographs of Inkerman from the late 19th century:

Image
Image

There are already developments

Image
Image
Image
Image

It generally looks like a giant quarry

Aqueduct in the Georgievskaya Balka.

Apparently ancient quarry I think some of the underground mining technology is shown. But questions remain where are all these volumes of limestone (even in destroyed form) and when was it mined?
