I too have had a look in here and like you, took one look at that collapse and thought no, not today.
If you live local would be worth doing some work to see if it was possible to shore that roof up - cos there’s every chance that the workings behind that collapse will be pretty substantial. ⚒
I do live fairly close and I’d love to see further in. Unfortunately I fear that shoring up an old mine roof sounds suspiciously like something that’s not within my very limited skill set! Haha! I suspect any intervention from me might make things a whole lot worse ;-)
