Meanwhile, last I looked anyway, regulations required a fire
extinguisher every 25 feet in a slate mine in Wales. I've never seen
slate ignited, but it must be nasty!
Slate : Metamorphosed shale. ie. clay just how hot would it
have to be to be ignited? Wonder what is flamable in a
slate mine?
...lew...
Also Dust...
Almost any dust is explosive when the mixture is right.
But the original was about a fire extinguisher every 25 ft
and I don't see how those would be of any benefit for a
dust explosion.
...lew...(lets remember the original post in the thread)
Im not sure that rock dust IS flammable.
Anyone?

I think it depends on the rock type. Coal dust will blow easily.
Graphite dust will as well. Basically it has to have a carbon content
high enough to allow it to oxidize. Or be an oxidizing compound in
itself. However even though they won't burn rapidly they can still melt.
Think lava...
