I must admit, like Roy, I could not see what this photo was about.
I have been "going underground", since the age of 14 which is a long time, the most recent, being yesterday.
I am a sceptic, about seeing mine ghosts, but I will admit there are times, when I do not feel happy in certain mine areas, one of which is the foot of Bowman's rise from Nentsberry Horse Level, to the Admiralty Flats.
It probably is the poor state of the roof, which I think all of us, must regard with care. At Bowman's a large timber, suddenly decided to drop down, hitting the floor, where a minute before my son had been standing!
Even in the best supported mines, the roof can drop, without any warning!
