Two miners timbering

Timbering involves the placement of wooden posts and beams underground to provide essential support to the sides and roofs of tunnels and shafts. This crucial practice is particularly necessary in coal mines where the type of rock in which coal forms tends to be soft. Without proper support, boulders may dislodge from the ceiling, and tunnels can be prone to collapse, emphasizing the importance of implementing timbering measures.
