Yes there were some low seams. There was a seam, i think at Seaton Burn colliery, where my brother worked in the 1970's, ( he worked at a few pits ) , some lads were saying if they took their shovel in the wrong way, you couldn't turn it, you had to come out and go back in.. Thats where he had his accident. My other brother was nearly killed at Ellington Colliery, he had his face smashed in.
