Abstract

To control winning and heading machines in underground mining, dust particles are drawn off in the area of the winning cutters, are scanned by optical refraction and are then gasified in a flameproof housing. The signals obtained from the optical refraction and/or the released gases are fed to the sensor which then controls the winning and heading machine in accordance with the signals determined.

Description

Die Suche nach Methoden, mit denen automatisch die Grenze zwischen Kohle und Gestein gefunden wird mit dem Ziel, damit automatisch Vortriebsmaschinen und Walzenschrämmaschinenlader steuern zu können, ist bekannt.The search for methods with which the Border between coal and rock is found using the goal to automatically drive and To be able to control roller cutting machine loaders known.

Die Zielsetzung ist deutlich geringerer Verschleiß und damit geringere Förderkosten bei genauer Fahrung in der Kohle. Es sind weltweit Untersuchungen durchgeführt worden, insbesondere über Sensortechnologien, jedoch die gewählten Verfahren brachten nicht den gewünschten Erfolg. The goal is significantly less wear and thus lower funding costs with precise driving in the coal. Investigations have been carried out worldwide been, especially about sensor technologies, however, the methods chosen did not bring the desired success.  

Leitfähigkeiten, Schaltleitfähigkeit, Reflektionsverhalten, Wärmewiderstand und mechanische Dichte im Meßverfahren reichen nicht aus, um eine praktikable Lösung zu ermöglichen.Conductivities, switching conductivity, reflection behavior, Thermal resistance and mechanical density in the measuring process are not enough to make a workable Enable solution.

Nachstehend wird erfindungsgemäß vorgeschlagen:
1.) im Bereich der Abbaumeißel Staubpartikel abzusaugen;
2.) diese Partikel innerhalb eines schlagwettergeschützten Rohres vom Laserstrahl zu erfassen und z. B. über einen Kohlendioxydlaser zu vergasen.
The following is proposed according to the invention:
1.) vacuum dust particles in the area of the chisel;
2.) Detect these particles within a fireproof tube from the laser beam and z. B. gasified via a carbon dioxide laser.

Die sich bildenden Gase werden einem Sensor zugeführt, der registriert, daß bei Kohlenstoffverbindungen selbstverständlich andere Substanzen freigesetzt werden als bei überwiegendem Gestein, staubhaltigem Material, und somit ist wieder über die Sensormessung in Ankopplung an die Schaltung der Gewinnungsmaschine, z. B. Walzenlader, eine Steuerung möglich.The gases that form are fed to a sensor who registers that carbon compounds are a matter of course other substances are released than with predominant rock, dusty material, and thus again via the sensor measurement in coupling to the circuit of the extraction machine, e.g. B. shearer loader, control possible.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen,
1.) im Bereich der Gewinnungsmeißel Staub abzusaugen,
2.) strahltechnisch nach Lichtpartikelmerkmalen und/ oder Vergasungspartikelmerkmalen eine Vorrichtung anzuregen, die den Steuerimpuls zu der Gewinnungsmaschine entsprechend auslöst.
Of course, the invention is not restricted to the forms of training described in detail above, but numerous modifications are possible without, however, deviating from the basic idea of
1.) vacuum dust in the area of the extraction chisel,
2.) to excite a device in terms of beam technology based on light particle characteristics and / or gasification particle characteristics, which triggers the control pulse to the extraction machine accordingly.
