Most likely:
It's not floating because as long as any single piece/chunk of one copper node is touching ground "the whole node is not yet flying".
They only fall apart on their own when they are completely disconnected, but some pieces can be below the ground - lower than you can dig.
This ^^ happens especially often when the copper node is already on a slope and not on flat ground (my observation).

I think you can even test this with the Stagbreaker for example.
Just like you can find buried scrap piles and silver veins without the wishbone.

I see... then is highly probably one node is below my reach so the whole thing dont collapse, thanks for the answers!

One quirk of the system is that floating objects can support each other.

Example: mining brain tissue in mistlands, excavating a skull from the mountainside - One rocky extrusion was still poking into the skull, despite both the skull and this rock having no connection to the ground. As soon as i found and broke that bit of rock, the whole skull fell to pieces.

Another example i've come across is silver veins intersecting. Even after i'd totally excavated both, neither would collapse, until i mined out the area where they touched each other.

Thanks for the answer, i dont mind uploading a screencap but literally is flying xD

First of all I took all the "dirt" around the copper
Then I started to mine below all the copper connected to the ground
After that I thought it will collapse but it didnt so I went and mine from below upwards hoping one node is supporting the rest
And lastly now I have a floating island of the first layer of copper wich dont collapse, and when I mine that part I died from fall dmg :$

its just a funny story now but a few hours ago I was tilted

Yes I think it needs to have somewhat like (at least) 4m of free space inbetween the copper node and anything else. When you've dug out the whole thing, it'll only start collapsing once you've mined out one bit so the other parts will "react" with it and -should- collapse. However, sadly it doesn't always work and as was said before; sometimes it's a bit buggy, maybe there's something somwhere inside that will still count as "ground" for the game.

My initial response was deleted, so I'll repost without the bit that was apparently offensive:

Copper will fall when it is completely disconnected. However, was is "connected" visually doesn't always match with what's connected as far as the game is concerned.

The easiest way to determine what is still connected to foundation is to use the mod "Ore Support." (I don't like it, but one of my friends loves it except in crypts, where it appears to cause a lot of lag.) It shows the bounding boxes of individual nodes and how/where the copper is still connected, and makes it easy to determine what exactly to strike to make the whole thing fall.

As for why fall damage is so high, I blame [insert figure that's been irrelevant for years].
