Spontaneous Combustion in Open Cut Coal Mines

Open-cut coal mining produces large quantities of waste material that must be disposed of around the mine site. Some of this material may be sufficiently reactive to begin to self-heat which can ultimately lead to spontaneous combustion in the spoil piles at some mines.
