Question about mining

[Glorthan]

I made the minehole like 12 tiles far from the huge ass cavern. They must be 2 different classes then and the generator must work acordingly to it.
What can happen if you make it in the middle of both?

To clarify, you're not talking about the first level? It seems to have different cavern systems.

Yes I do. I have a minehole inside a cave system. Ill paste a pic in 20 min about, let me edit this then showing it to you.

Cave system is level 1. Minehole inside goes to level 2. 1 is different to 2 and below.

True, true. So you mean that a level 2 cavern will be the same until level 5.
I was answering evilboy whe I sayd that, then i misenderstood you.
He sayd:

Try to make your hole in a cave if you can. There are cave systems in every layer now and caves are similar in every layer. So from there you can search the walls and find the good q parts

So I understood that from a level 1 cavern you would acces to something similar in below layers.

This is my cavern:


My minehole is 34 tiles away from it, in a cave way. And as a result i got a black area. :/
