Miners in a timbered tunnel. Historical artwork of workers in a 19th century mine,loading debris and rocks onto a wagon. Timber was used in mines to support the roof. The construction consisted of two upright beams joined by another across the ceiling. These were spaced out and joined by lateral beams. Often the wood would break,necessitating rapid fixing to avoid the danger of a cave-in. In the UK the wood of choice was Larch and Oak. Taken from Mines and Miners,L. Simonin,1868 | |
