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.
