Advanced Photonics Australia''s Director Ubaldo Torre is proud to announce the signing of a contract with Glencore Coal. The contract will provide a fully redundant fibre optic cable DTS based fire detection system for the Bulga Coal Handling Plant for the surface and reclaim tunnel conveyors. The system will provide area coverage from the run [.]
cases, especially in enclosed spaces, the location of the sensor cable may have to be closer to the conveyor ceiling height. This type of application is a so called "room protection" application, where the sensor cable is located at a distance away from the main fire risk. "Room Protection" is defined within EN54 part 22 para
MVWS for coal conveyors shall be provided for both top and return conveyors. Junction towers, transfer towers, crusher house and all other areas shall also be covered. Fire in the coal conveyor will be detected by the linear heat sensing cables and infrared ember detectors which shall provide signal for electrical actuation for deluge valve.

Conveyor belt temperature monitoring and fire detection Conveyor belts running in dusty and harsh environments, such as mines, run the risk of overheating bearings that can lead to catastrophic fires especially when transporting flammable material like coal.
Apr 24, 2007· Conveyor controls shall be so arranged that, in case of emergency stop, manual reset or start at the location where the emergency stop was initiated shall be required for the conveyor(s) and associated equipment to resume operation." It doesn''t specifically say how to reset the conveyor, and that the motor restart needs to be a separate operation.
To date, coal conveyor fire protection systems have typically involved the use of line/spottype heat detection technology coupled with a sprinkler system. These components are generally hung ...
sufficient to ignite coal dust, CH4, coal dust/ air mixture or any hydrocarbon vapors from the grease, paint, seal etc. Fire Resistant (FR) grease has been adopted for idler end bearings in the UK coal mining industry since 1986 as it is less likely to ignite if exuded from a bearing during collapse.

The guideline applies to all coal mines in New South Wales and provides recommended minimum fire protection requirements for – a) surface plant and infrastructure (such as buildings, offices, surface mobile plant, processing plants, coal stockpiles, conveyor belts and other fixed plant), refer SECTION 3.
an approved automatic fire protection system. (5) Unattended electrical equipment located on noncombustible material and spaced at least m (2 ft) from coal or other combustible material shall not be required to be protected with an automatic fire suppression system.
The calibrated model was used to investigate the effects of sprinkler location, water flow rate, and sprinkler activation temperature on the suppression process. The simulation results can be used to design more effective fire protection systems for the conveyor belts used in underground coal mines.
The general rule in fire protection systems for conveyors is to locate Ember Detector(s) upstream from a change in direction (transfer to another conveyor) or a dust producing process or storage point. Hence, once the ember is detected, it can be extinguished before it enters the next process where it can cause a potential explosion.
