In underground mines, conveyor belt systems move coal and other materials. A typical coal mine may have as many as 20 conveyor belts, some of which may be as long as 20,000 feet.
Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust.
