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

Sep 01, 1995 To date, coal conveyor fire protection systems have typically involved the use of line-/spot-type heat detection technology coupled with a sprinkler system.
On the basis of the analysis carried out in order to protect the inclined coal conveyor against fires, we designed a fire detection, alarm and extinguishing control system (FDAECS). The protection extends along the inclined coal conveyors system, within which we used linear thermal detectors (sensor cables) and manual call points. Furthermore, we applied fixed extinguishing devices in
Coal Conveyor Fire Protection. Conveyors in mines and quarries for heavy material handling are the most important logistics management asset on the site, delivering the raw or product material from the mine excavation right through to shipping. A fire on a conveyor system can start from multiple sources, including the material being transported itself, right through to overheated
Hydraulic systems should only use listed fire-retardant hydraulic fluids. Automatic sprinkler or water spray systems should be employed for fire protection of coal handling structures that are critical to power generation where coal or coal dust is likely to be accumulated. Fire protection to pulverizers. Design shall be in accordance with NFPA 85.
Jan 27, 2016 The majority of industrial fires which begin on or around conveyor systems occur as a result of ignited coal dust in underground mining operations.
