Coal Mine Safety (anthracite coal mines) timbering and pre-shift examination

Описание к видео Coal Mine Safety (anthracite coal mines) timbering and pre-shift examination

Mine safety videos that cover timbering and pre-shift safety checks. I can't even remember where I got these but they probably came from when I took my underground mining safety training (40 hours plus an exam). These are specifically about anthracite mining. I do not own the rights but I felt them worth sharing as they now serve as a nice snap-shot of our mining heritage.
