Dog runs from mine worker (6)
I believe the answer is:
collie
'dog' is the definition.
(collie is a kind of dog)
'runs from mine worker' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'from' is a deletion indicator.
'mine worker' becomes 'collier'.
'collier' with 'r' taken out is 'COLLIE'.
(Other definitions for collie that I've seen before include "Border dog" , "Popular kind of sheepdog" , "Sheepdog wth ling nose and shaggy hair" , "shepherd's gofer" , "Breed of dog" .)
