Problems solved by technology

However, the optical display devices used for this have proved to be problematic in that the visibility in the immediate vicinity of the mining machine is very unfavorable due to the dust formed there and the water mist sprayed there to remove the dust.

Embodiment Construction

[0018] The drawing shows a cutting-type mining machine, generally designated by the reference number 1 , which is designed here as a drum shearer. The mining machine has a body 2, which is provided at the front and rear with swivel arms 3 and 4 on which cutting drums 5 and 6 are supported. The body 2 is supported by undercarriages 7 and 8 which can be moved on a working surface conveyor 9 which also serves as a running track. The working surface conveyor 9 is designed as a scraper conveyor, the upper branch of which serves as the conveying branch of the chain and the scrapers and the lower branch of which serves as the return branch of the chain and the scrapers. The machine body 2 is mounted on the running gear 7 and 8 in such a way that the mining machine 1 bridges the conveying branch of the face conveyor 9 in a gantry-like manner, so that mined material located in the conveying branch of the face conveyor can pass through the mining machine 1 .

Abstract

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.

Description

technical field [0001] The invention relates to a method and a device for monitoring the travel path of a cutting-type mining machine, which is used, in particular in coal mining, on a longwall face mining machine equipped with a face conveyor and a walking frame The working surface can move along the working front wall (Abbaufront). Background technique [0002] In coal mining, it has proven particularly difficult to monitor the travel path of the cutting machine with respect to obstacles in the automatic or remote control of cutting machines used in longwall mining. For this reason, in such use of cutting-type mining machines, it always happens again and again that the cutting drum or the top end of the support arm of the mining machine is in contact with the lowered cover beam or the hanging flip cover of the walking-type support, Collision of sliding covers or other attachments, and / or jamming of the mining machine or face conveyor, because the conveying branch of the f...
