I have something to add in regard to this:

So perhaps that section "B" doesn't have any ore and is just rock, so that actually triggers the mining restriction?
I had ore right up to the minable tiles - 51st tiles - from entrance but couldn't mine into the 50/49 etc tiles - it's easier to explain with a screenshot, i'll come back and edit ............................give me 5 minutes.
Point being, mining restrictions can't be triggered by lack of ore, I still couldn't mine into entrance tiles like Tonky has done when there was ore.
(Lol, i'm confusing myself - does that make sense?)
Edit:

Just read your update borka - so it's width that is different - i've only tested one side, to the left of cave entrance on mine it is still the 51st tile that becomes mineable. Circled in blue on tile and on mini-map. Have yet to mine further in, towards entrance - building support now.
