Does anyone know of a music supervisor looking for folk/bluegrass tunes about mines?

Answer 1

Your question is kind of confusing; are you looking for songs about mines or mining?

Last day in the mines - Dave Dudley

Dream of a miner's daughter (or child)- Doc Watson (others have sung this one over the years too)

Coal Miner's Daughter - Loretta Lynn

Big John

16 Tons

(I don't remember who sings these last two songs, but you got the titles, I'm certian you can locate them.
