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.
New requirements in China's coal industry. Subsequent to a decree of May 2013, according to which main steel cord conveyor belts have to be equipped with a belt and splice health monitoring device, a further tightening is coming into force: As of October 2016, all belt conveyors must be equipped with a rip detection device.
May 28, 2004· The reason why we make belt conveyors into a radius shape to start with is to stop the product from moving off of the sides and onto the floor.

Because coal mining operations use conveyor belts extensively to move materials, you must be able to count on your mining equipment to work efficiently without unscheduled downtime. Every time you have to stop production for unexpected problems like repairs or housekeeping, profitability drops.
Primitive conveyor belts were used since the 19th century. 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.
Before the development of suitable conveyor belts, coal was transported from the mine by rail transport systems, but today coal transport is almost invariably by conveyor belts. In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a mine with only shaft access winding or hoisting of coal in the shaft ...

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.
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 and the use of belt air at the face. The ...
