Left coal mined in the vicinity (5)
I believe the answer is:
local
'in the vicinity' is the definition.
(I've seen this before)
'left coal mined' is the wordplay.
'left' becomes 'l' (common abbreviation).
'mined' indicates anagramming the letters.
'coal' anagrammed gives 'ocal'.
'l'+'ocal'='LOCAL'
(Other definitions for local that I've seen before include "Regional; nearby" , "Nearby pub" , "One's nearest pub" , "Anaesthetic that numbs one area of the body" , "Nieghbourhood pub or its customer" .)
