What did they do with the flame retardants? Spray parts of the mine with them?

A lot of things in a mine is made of wood.

Even worse, a lot of things in a coal mine are made of coal or are covered in coal dust. Flammable powders can be ugly, particularly if they're floating.

I don't think they are worried about wood. Coal dust
