Coal stored here in sink deliberately (7)
I believe the answer is:
scuttle
'sink deliberately' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for scuttle that I've seen before include "Coal container for fireside" , "Rush" , "Sink with cutlets" , "Move hurriedly" , "Sink one's ship deliberately" .)
