Explosives come down to quarries (9)

I believe the answer is:

landmines

'explosives' is the definition.
(I've seen this before)

'come down to quarries' is the wordplay.
'come' becomes 'land' (landing is a kind of coming).
'down to' is a charade indicator (letters next to each other) (joining in a down clue).
'quarries' becomes 'mines' (I've seen this before).
'land'+'mines'='LANDMINES'

(Another definition for landmines that I've seen is " Explosives".)

I've seen this clue in The Daily Express.
