That's very unusual and a red flag that there's some safety problems at that mine.

I would say that these are indicative of an operator who wasn't going to let safety get in the way of production.

That is a very high number, and it is usually indicative of a very poor safety record.

It's the next enforcement step and it's never used.

With the price of coal so high, you have operators coming out of the woodwork, trying to get into any seam of coal they can to make a quick buck, opening up a lot of little dog holes.

You can't expect miners to come in and testify about unsafe conditions in the mine when you have their employers across the table from them.
