What was a coal miners life like?

The life of a miner is very dangerous. If one thing goes wrong all the rocks that the miners have put to the side while mining can come crashing down and kill the miners. Also life as miner is very dangerous because when u blow up a wall so u can get past it you have to make sure everyone is a safe distance away and u also have to make sure u set the bomb up right so nothing goes wrong and no one gets hurt. Most miner employers don't care about their workers and the working conditions so the environment itself is bad.
