Hard rock and pellets tend to wear a conveyor belt faster than coal, for example. Material density and the speed at which the belt is running can also impact the rate of belt wear. The other type of abrasion is cutting and gouging, usually from jagged or sharp surfaces like limestone, granite, ores, etc.
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.
