I was thinking of specifically The Blackleg Miner which has been discussed HERE as being a Bert Song based on an American prototype.

Do you have a problem with British singers adopting songs from America? It was possibly inspired in part by "Which Side Are You On?". The origins of that one are not in any doubt and owe nothing to the revival.

A local one is the Midlothian Miners Song, which dates from the 1970s. Its author was a miner from Gorebridge or Arniston - he doesn't seem very keen on being traced and has never shown up in local folk and trad venues. He adapted a song from the coalfields of north-east England, which is in one of Roy Palmer's collections, but whether he got it from Palmer or some independent route from the original broadside I don't know. (It was published in Billy Kay's "Odyssey" collection - Kay didn't know where it came from either).

Mining communities have a lot of skilled musicians (hence the success of colliery bands and, in Scotland, the number of miner-fiddlers there have been). They'd get bored doing nothing but agitational songs, but there's no doubt they can turn their hands to them when they want. The Newtongrange Folk Club was run by ex-miners and people from minng families since it started. They may not be as revolutionary as Lloyd would have liked but they have musical skills he would have respected.
