About: Timbering in Underground Anthracite Mines (Part 2)


I don't understand how you can slide in the planking or get the 4 poles in when it's so tight to the roof. Here for the demonstration, they have room to tip the wood all they want, as nothing is above them. But how do you get those pieces to fit in there when the rock is so close?
As an underground miner myself, this video is really informative. I mine calcite crystals in a copper mine in Norway, and are looking for cheap and safe ways to support the drift. Thank you for this one.
What are they making?
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. ^ 5 gragor
