Acclamation and praise in the mines (8)
I believe the answer is:
plaudits
'acclamation' is the definition.
(I know that acclamation can be written as plaudits)
'praise in the mines' is the wordplay.
'praise' becomes 'laud' (lauding is a kind of praising).
'in the' is an insertion indicator.
'mines' becomes 'pits' (I've seen this before).
'laud' inserted into 'pits' is 'PLAUDITS'.
'and' is the link.
(Other definitions for plaudits that I've seen before include "Accolades" , "Acts of acclaim" , "Enthusiastic approval" , "Emphatic expressions of approval" , "Acclamations" .)
