Fire Safety & Prevention for Non-Mining Conveyor Systems

Jan 27, 2016 The majority of industrial fires which begin on or around conveyor systems occur as a result of ignited coal dust in underground mining operations. But while the fire risks of the fossil fuel industry are well-known and documented, fires involving belt conveyors or other material handling systems are far from restricted to this sphere of

More

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.

TRI-containing products are used in underground activities for splicing endless conveyor belts and to repair them. At the RAG 177 km of belt conveyors are operated underground. On these, the conveyor belt runs on idlers endlessly and the total length of the conveyor belt (upper and lower belt) sums up to 2 x 177 km = 354 km.
