State of coalminer working around bottom of mine (10)
I believe the answer is:
Here is my best explanation:
'state' is the definition.
'coalminer working around bottom of mine' is the subsidiary indication.
'working' indicates anagramming the letters.
'around' is an insertion indicator.
'bottom of' suggests the final letters.
The last letter of 'mine' is 'e'.
'coalminer' with letters rearranged gives 'cermonial'.
'cermonial' going around 'e' is 'ceremonial'.
'of' is the link.
(Other definitions for ceremonial that I've seen before include "ritual", "Official", "Ritual(istic)", "Ritual procedure" and "Purely formal".)
