in the mine, either lodged on timbers or the floor, is lifted into the air by the 'flame front' where, because it is so fine, each particle exposes a large surface area to the oxygen of the atmosphere and so absorbs oxygen from the air, which, in the event of a gas explosion, enables the coal dust
to transmit the flame from one particle to the next in a massive chain reaction.
