Mine dump recalled (3)
I believe the answer is:
pit
'mine' is the definition.
(down the pit)
'dump recalled' is the wordplay.
'dump' becomes 'tip' (as in a rubbish tip).
'recalled' says the letters should be written in reverse.
'tip' back-to-front is 'PIT'.
(Other definitions for pit that I've seen before include "where orchestra plays" , "Take stone" , "Hellhole?" , "Large deep hole in the ground" , "See 9" .)
