Despite the initial progress, it cannot be ruled out that some unsafe coal mines are still in operation, and we will continue to strengthen our supervision and inspection.

The public schools, trade schools and research schools, these are the coal mines of the 21st century,

Coal mines make the news only when they explode, collapse, kill. It's exciting! Tragedy! Fodder for a cable-news frenzy.

Unsafe at any speed

I don't know how they could really make mines much safer than they are. What else can they really do.

We supply units for equipment like bulldozers, coal hauling trucks and cranes, plus strip mines. It's essentially a four-month business, but now makes up about half of our total business.
