Mine explosion in WV

My thoughts go out to those families of the miners. I come from a family of coal miners my self. Three of my uncles and my dad all worked in the coal mines. One of my uncles was killed in a mine accident, they say a shield came loose and crushed him. My dad was almost killed when a rock face let loose and hit him, luckily he was watching and moved in time, his leg was hit and messed up. They are retired now, I am very thankful that they are alive. There health might not be the best breathing all the coal dust. We often times forget what these men and women do for the country by providing us with electricity.
