6 Construction and Maintenance of Belt Conveyors for Coal and Bulk Material Handling Plants also oscillating horizontally. This phenomenon results in internal agitation to the material on belt and therefore the material''s external faces assume inclination at surcharge angle.
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.

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

panel during development and mining would be extreme. Now the need surpassed the risk and the application of intermediate drives to limit belt tensions and allow the use of fabric belting on long center applications was actively pursued. Today, intermediate drive technology is very well accepted and widely used in underground coal mining (Table 1).

Conveyor systems can be used to transport material in underground and open pit operations, and are especially common in coal mines (Betz, 1998). The simplicity and increased reliability of conveyor systems make it an attractive alternative to conventional truck haulage.
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coalfired power plants, according to the Energy Information Administration.
