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.

Conveyor belt fires are significant risks Martin Engineering

An electrostatic charge may build up on the conveyor belt surface and ignite a mixture of flammable gases and air. By keeping the surface resistance of the belting low (making the belt cover more conductive), the conveyor belt allows the charge to flow freely, eliminating the risk of sparks. High-Energy Propane Burner Test (EN12881)
