Dog runs away from miner (6)
I believe the answer is:
collie
'dog' is the definition.
(collie is a kind of dog)
'runs away from miner' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'away from' is a deletion indicator.
'miner' becomes 'collier' (collier is a kind of miner).
'collier' with 'r' removed is 'COLLIE'.
(Other definitions for collie that I've seen before include "Popular sheepdog like Lassie" , "See 2" , "Sheepdog wth ling nose and shaggy hair" , "Farm dog" , "Popular kind of sheepdog" .)
