Coal trip day 4 7/20/11 exhibition coal mine

The most interesting thing i learned from the mine tour was that roof bolts had to be ancored in 1 foot of solid rock. I was amazed when Marvin said how far he had drilled in the bolts.
The scool house was interesting with the rules.
Below is a picture of a miners helmet. I picked this one because it is similar to the one my dad wore when he was a miner.
