Timbering in Underground Anthracite Mines (Part 2)
DVD589 (Was VC807) - 1994

Timbering is the most common roof support method used in underground anthracite mines. The system of timbering is governed by the character of the top and bottom, thickness of the coal vein, pitch of the coal vein, life of the entry, haulage system, and the operator's approved roof control plan. This videotape demonstrates the fundamentals and characteristics used in installing typical timber sets: single prop, post and bar (two-piece sets), and "double timber" (three-piece sets).

Thanks. Glad you found some miners that knew how to do this before they passed on.

I worked in a silver lead zinc mine in the yukon and the walls were covered in lagging in square sets to the point were you really couldn't see the walls or the back.

I nipped what seemed like a million flatcars of timber in that mine but never got to see it going in.

Now I can picture how it was done.
