Underground safety of conveyor belts

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. The fire safety requirements are similar for the most hard coal mining countries.

Coal Dust: How to Prevent a Power Plant Explosion — F.E. Moran

Jul 27, 2018· Coal dust only needs to accumulate to a footprint size and already it is a fire hazard. As the conveyor moves, any friction that occurs can be enough of a heat source to cause an explosion. Any machine that is not running impeccably can cause friction and, as a result, a heat source. Other causes of heat sources are . Friction through mixing ...
