Independent analysis of heat and fire detection for ...
The Mine Ventilation Society of South Africa (MVSSA) has published the results of a study where they compare different fire prevention and detection systems for mine conveyor belts. Conveyor belt fires are one of the leading risks, especially in the underground mining industry. Often combustible materials are used on and around the conveyor installation.
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.

Fire protection for conveyor belts. Automatic conveyor systems are the lifeline for many companies. They guarantee continuous flows of material and goods by transporting these items to all areas in the company, through openings in fire walls and ceilings. This …
Fire Resistance of Conveyor Belts - 911metallurgist.com
Conveyor belt fires can present a serious hazard in the confined environment of an underground coal mine. To minimize this hazard, Federal regulations were enacted following the Federal Coal Mine Health and Safety Act of 1969 to require the use of acceptable fire-resistant conveyor belts and suitable belt slippage-sequence switches, fire warning devices, and fire suppression systems.
Conveyor Belt Guide, with tons of free info
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. China is by far the worlds largest consumer of conveyor belts.

Improvments in Conveyor Belt Fire Suppression Systems for ...
Fire Suppression systems are the first line of defense after a conveyor belt fire has started in an underground coal mine. Between 2000 and 2009, twenty-five 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
US7673739B2 - Apparatus and method for in-belt conveyor ...
A method and system are provided for in-belt conveyor idler condition monitoring. A sensor is mechanically coupled to a conveyor belt and senses a characteristic of a support structure associated with the conveyor belt. The sensor wirelessly transmits a corresponding signal to a monitor system. The monitor system determines a condition of the support structure based upon the transmitted signal.
