5000 deaths a year

I just heard about the 102 miners trapped in a flooding coal mine in southern China. Apparently over 5000 miners die every year due to disasters in mines.

Kentucky has coal mines. I’m pretty sure conditions used to be pretty bad, but I honestly don’t know much at all about them, including how conditions are today.
