Where to find the colliery boss? (7)

Ross

I believe the answer is:

pithead

I'm a little stuck... Click here to teach me more about this clue!

'where to find' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'colliery boss?' is the wordplay.
'colliery' becomes 'pit' (synonyms).
'boss?' becomes 'head' ('head' can be a synonym of 'boss').
'pit'+'head'='PITHEAD'

'the' acts as a link.

Can you help me to learn more?

(Other definitions for pithead that I've seen before include "area of mine" , "something over working?" , "top of shaft" , "is partly mine" , "Ground round mouth of mine" .)
