Some 40 years ago, the strongest conveyor belt was an St 4000, used in an underground coal mine in Europe (St 4000, the rating as per DIN 22131, stands for a minimum breaking strength of 4,000 N/mm of belt width). A Phoenocord St 5400 was supplied for the German hard coal mining .
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the ...
The belt is more rigid across the width than a conventional conveyor belt as it must support both its own weight and the material load. Additionally, the belt is designed to deflect a specific amount under load according to the capacity and characteristics of the material to be carried.
Current regulations for fire suppression systems in underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the ...

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.
In 1892, Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products. In 1901, invented and started the production of steel conveyor belts. In 1905 Richard Sutcliffe invented the first conveyor belts for use in coal mines which revolutionized the mining industry.
About Us . William G. Zimmermann and Mark Alspaugh, founded Overland Conveyor Co., Inc. (OCC) in 1993. Both principals had extensive belt conveyor backgrounds with manufacturers such as The Goodyear Tire Rubber Co. and Continental Conveyor Equipment Co. prior to this endeavor.

after a conveyor belt fire has started in an underground coal mine. Between 2000 and 2009, twentyfive fires in underground coal mines were caused by friction of conveyor belts against pulleys, drives, rollers, idlers, and bearings (MSHA). These fires were often not detected for long periods of time after ignition, making manual fire
Beltconveyors are more acceptable than other means of transporting bulk materials; they neither pollute the air nor deafen the ears. Belt conveyor is one of the main transport equipment in coal mine, driving drum and belt is its key part. Friction principle is used to initiate mechanical drive for belt conveyor.

The largest coal producing countries are not confined to one region – the top five hard coal producers are China, the USA, India, Australia and Indonesia. Much of global coal production is used in the country in which it was produced; only around 15% of hard coal production is destined for the international coal .
Since introduced in the early 20th century, conveyors have become a vital part of mine operations. Conveyor systems can be used to transport material in underground and open pit operations, and are especially common in coal mines (Betz, 1998).
Maximize belt life. Installing multiple motors on long conveyors is common practice. Apply drives to ensure load sharing between each motor for reliable operation and to maximize belt life. Danfoss drives include both MasterMaster and MasterFollower control solutions for this.
