Abstract (en)
[origin: WO2010017823A1] The invention relates to a method and to a device for monitoring the track of a cutting extraction machine (1), which is used in particular in coal mining and can be displaced during longwall mining in a longwall face equipped with face conveyors (9) and longwall advancing (12, 13) along the face (10). The underlying object of the invention is to create a method and a device which make it possible, despite extremely poor visibility conditions, for example in the track of the extraction machine, to detect present obstacles in the form of lowered canopies or drooping folding canopies, sliding canopies or other additions to the lining or overloads of the conveyor in order to take measures for avoiding interruptions in the operation in a timely manner. In order to achieve this object, according to the invention the track of the extraction machine (1) is scanned using a radar measuring device (14) associated with the extraction machine (1) and upon detection of an obstacle an alarm is triggered and/or an invention in the controller of the extraction machine (1) takes place.
