I have a song about mining - it is just called 'pit song'in my book - the chorus starts 'Jowl jowl and listen lad, hear the coal face working'

the last verse starts
Now the deputy crawls from flat to flat
Whilst the putter shoves the empty 'uns

I heard in a song someone had written, a referrence to 'tyumuns' - which - when I asked - was a dialect work for empty tuns, taken from another song.

I don't think so...
