With police appearing, miner agreed to move (11)
I believe the answer is:
gendarmerie
'with police' is the definition.
'gendarmerie' can be an answer for 'police' (I've seen this before). I am unsure of the 'with' bit.
'miner agreed to move' is the wordplay.
'to move' indicates anagramming the letters.
'miner'+'agreed'='mineragreed'
'mineragreed' anagrammed gives 'GENDARMERIE'.
'appearing' is the link.
Can you help me to learn more?
(Other definitions for gendarmerie that I've seen before include "French paramilitary police" , "French policing force" , "foreign force" , "Police force" , "Nick" .)
