MINING COAL - METHODS -
Long Wall
Long wall mining worked in a different way. Tunnels were
dug into the coal seam, usually supported by pit props and
pillars of rock and then miners worked along face of the coal
seam removing coal as they worked.
Timbering was carried out along the areas being mined
but the area in behind from which the coal had been mined
was allowed to collapse.
Long wall
mining was usually done on thin coal seams up to about 5
feet (1.5 metres) in thickness.
