A belt conveyor, as distinguished from a chain conveyor, provides a moving surface (the belt) on which material is placed and transported. ~962
l The key difference is that MSHA specifies flying or falling material from the operation of “screens, crushers, or conveyors”. l Based on this language, and the recommendations in their “Guide to Equipment Guarding” (2004), some MSHA personnel have required conveyor return idlers to be completely enclosed.
In its RFI MSHA notes that “mining safety could be substantially improved by preventing accidents that involve mobile equipment at surface coal mines and metal and nonmetal mines and belt conveyors at surface and underground mines.”
Internal review concluded that MSHA inspections of the belt entries at Aracoma Alma Mine No. 1 failed to identify the inadequate fire suppression systems in the belt entries and that MSHA inspection personnel did not effectively enforce the requirements of water sprinkler systems at the mine.
This PIB applied only to metal and nonmetal mines. The PIB provided information on MSHA’s requirements for start-up warnings for both manually operated and automatically operated conveyor belt systems at metal and nonmetal surface and underground mining locations. This reissued PIB would be applicable to metal and nonmetal and surface coal mines.

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.

Jul 05, 2018· As the mining industry continues to wait for any new direction at MSHA to reveal itself, last week, MSHA published a request for information (RFI) in the Federal Register that could be the beginning of a new rulemaking on powered haulage equipment. The RFI covers aspects of both surface and underground mines, as well as both coal and metal/non-metal.

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.
Jul 06, 2018· On June 25, 2018, MSHA issued a request for data regarding new or existing technologies that can help improve miner safety. The Request for Information (RFI), which was published in the Federal Register on June 26, 2018, centers on mitigating incidents involving mobile equipment and belt conveyors at surface and underground mines.

Jun 20, 2017· Not surprisingly, the standards’ lack of specificity led to some confusion among mine operators as to when fall protection actually was required. On June 21, 2012, MSHA issued a program policy letter (PPL) in an attempt to clarify its enforcement position regarding fall protection for surface and underground metal and non-metal mines.
Dec 31, 2008; MSHA published a final rule today that requires flame-resistant conveyor belts and other fire protection measures in underground coal mines but still allows operators to use belt air -- ventilating active mining areas by using the shafts through which conveyors move coal to the surface.
Belt air is the practice of bringing air into mines for miners to breathe through the same tunnels that are used to take coal out of the mine on conveyor belts. The objective of this proposed rule is to improve mine safety by significantly reducing the hazard of conveyor belt fires in underground coal mines, said MSHA Administrator Richard E. Stickler.
• The new BELT standard only applies to coal mining. It does not address any other types of underground mine for example – salt mines or limestone mines. • It does not address any above ground conveyor belt application like surface belts at a mine site or belts at preparation site or power plants.
