Description
Die Erfindung betrifft ein Verfahren zur Steuerung von Gewinnungsmaschinen, beispielsweise Walzenschrämladern und Teilschnittmaschinen, im untertägigen Bergbau, die über An ordnungen zum Absaugen von beim Eingriff der Schrämmeißel in den mineralischen Stoff an diesem freigesetzten Staub ver fügen.The invention relates to a method for controlling Extraction machines, for example roller cutters and Partial cutting machines, in underground mining, which over An Regulations for suction when engaging the cutter bit in the mineral substance on this released dust ver put.
Bekannt ist es (DE-OS 28 00 990), mit Hilfe eines Lasers den Staubgehalt von Gasen in Gaskanälen zu bestimmen. Aus der GB-Zeitschrift "Colliery Guardian", Mai 1971, Seiten 228 bis 231, ist ein Vorschlag zu entnehmen, wie ein Schneid körper einer Teilschnittmaschine mittels Sensor gesteuert werden kann. Die DE-Zeitschrift "Glückauf-Forschungshefte", 40 (1979), Seiten 19 bis 24, erläutert ein Verfahren, nach dem der Staub abgesaugt wird, der beim Schneiden des mineralischen Stoffs durch Walzenschrämlader oder Teilschnittmaschinen entsteht. Die staubhaltige Luft soll dabei möglichst dicht am Entstehungs ort abgesaugt werden, um so die Wetterführung zu entlasten. Nachteilig bei diesem bekannten Verfahren ist, daß zwar auf die Problematik des anfallenden Staubes hingewiesen, Lehren zur Vermeidung des Staubanfalls allerdings nicht ge geben werden. Auch fehlt es an Hinweisen, wie man eine Maschine u. a. zur Verringerung des Staubanfalles über die Identifizierung des Staubes steuern kann.It is known (DE-OS 28 00 990) using a laser determine the dust content of gases in gas channels. Out GB magazine "Colliery Guardian", May 1971, pages 228 to 231, a suggestion can be found like a cutting body of a partial cutting machine controlled by a sensor can be. The DE journal "Glückauf Research Books", 40 (1979), pages 19 to 24, explains a method by which the dust that is sucked away when the mineral material is cut Roller cutter loader or partial cutting machine is created. The dusty air should be as close as possible to the source be sucked off to relieve the weather. A disadvantage of this known method is that pointed out the problem of the resulting dust, Lessons to avoid dust accumulation, however will give. There is also a lack of instructions on how to get one Machine u. a. to reduce the amount of dust on the Can control the identification of dust.
Die Erfindung liegt daher die Aufgabe zugrunde, eine Steuerung für Gewinnungsmaschinen im untertägigen Bergbau mit den benötigten signifikanten Meßwerten zu versorgen, die eine einwandfreie Unterscheidung der anstehenden mineralischen Stoffe und damit einen genauen Trennschnitt zwischen diesen zu ermöglichen. The invention is therefore based on the object Control for mining machines in underground mining to provide with the required significant measured values, the a perfect differentiation of the upcoming mineral Fabrics and thus a precise cut between them too enable.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die mit den abgesaugten Staubpartikeln beladenen Wetter einem Rohr zugeführt, über einen Laserstrahl lichtintensitäts mäßig untersucht und/oder in einem schlagwettergeschützten Gehäuse vergast und bezüglich der substanztypischen Gasbe standteile mittels Sensortechnik überprüft werden und daß die Signale der Steuerung mitgeteilt werden.The object is achieved in that the weather loaded with the extracted dust particles fed to a tube, light intensity via a laser beam moderately examined and / or in a fireproof Gasified housing and with respect to the typical gas gas Components are checked using sensor technology and that the Control signals are communicated.
Ein derartiges Verfahren ermöglicht es, die Lösewerk zeuge von Walzenschrämladern und Teilschnittmaschinen in einem Bereich zu halten, der eindeutig innerhalb des Kohle flözes und jeweils genau so im Übergangsbereich liegt, daß möglichst Nebengestein nicht oder, wenn unbedingt notwendig, in nur ganz geringem Maße mitgeschnitten wird. Die hierfür not wendigen Signale werden letztlich aus den substanztypischen Gasbestandteilen ermittelt, wobei durch Einsatz des Laser strahls die Möglichkeit gegeben ist, diese Überprüfungen unmittelbar an bzw. in der Maschine vorzunehmen. Besonders vorteilhaft dabei ist, daß eine Doppelüberprüfung insofern erfolgt, als die Staubpartikel bezüglich der Lichtintensität überprüft werden und zusätzlich nach der Vergasung eine zusätzliche Kontrolle durch Überprüfung der Gasqualität bzw. der Gaszusammensetzung durchgeführt wird, so daß die daraus sich ergebenden Signale die angestrebte genaue Führung der Gewinnungswerkzeuge ermöglichen.Such a method makes it possible to solve the problem witness of shearer loaders and partial cutting machines in to keep an area that is clearly within the coal seams and in each case exactly in the transition area that as possible No secondary rock or, if absolutely necessary, only is recorded very little. The necessary for this Agile signals ultimately become the substance-typical Gas components determined, using the laser is given the opportunity to do these reviews to be carried out directly on or in the machine. Especially The advantage here is that a double check in this respect takes place as the dust particles in terms of light intensity be checked and additionally after the gasification additional control by checking the gas quality or the gas composition is carried out so that the resulting signals the desired exact Allow management of the extraction tools.
Nach einer zweckmäßigen Weiterbildung der Erfindung ist vorgesehen, daß die abgesaugten Staubpartikel über einen Kohlendioxydlaser vergast werden, so daß über die Ermittlung der Kohlenstoffverbindungen in den untersuchten Gasen eine genaue Unterscheidung zwischen Kohle und Nebengestein möglich ist.According to an expedient development of the invention provided that the extracted dust particles over a Carbon dioxide lasers are gasified so that the determination one of the carbon compounds in the gases examined precise distinction between coal and bedrock possible is.
