Abstract

Coal-winning machines which are used in underground mining, in particular in longwall operation, are provided with torque recorders which lift or lower the winning tools according to a predetermined current input, i.e. they move the winning tools away from the rock into the coal area or vice versa in a regulated manner. Automatic control of these winning machines is thus possible.

Description

Insbesondere Walzenschrämmaschinen werden heute mit sehr hohen Leistungen ausgeführt, damit sie plötzlich anstehendes Gestein zerschneiden.Especially roller cutting machines are used today very high performances so suddenly they run cut up the existing rock.

Die Antriebsleistung wird entsprechend der mitzu­ schneidenden Gesteinsschicht ausgelegt.The drive power is according to the mitzu intersecting layer of rock.

Damit die Gewinnungsmaschine automatisch den kohlen­ führenden Schichten nachfährt und bei angrenzendem Gestein sich praktisch auf Grund der höheren Schneid­ kraft, die aufgebracht werden müßte, automatisch abduckt und der Kohle nachfährt, wird erfindungsge­ mäß vorgeschlagen, eine drehmomente Aufzeichnung in Unabhängigkeit von der Kohlefestigkeit so aufzunehmen, daß bei Überschreitung der vorgesehenen Drehmoment­ kraft die Walze sich absenkt, d.h. beim Schneiden im Hangenden oder vom Liegenden höher geht, um damit nur Kohle zu schneiden und eine sauberere Kohle­ förderung zu garantieren.So that the extraction machine automatically coal leading layers and adjacent Rock practically due to the higher cutting force that should be applied automatically prints and traces the coal, is fiction, proposed a torque recording in Independence from carbon strength so  that when the intended torque is exceeded force the roller lowers, i.e. when cutting in the hanging or from the lying to go higher just cut coal and a cleaner coal guarantee promotion.

Claims (1)

Verfahren zur Steuerung von Kohlegewinnungsmaschinen dadurch gekennzeichnet, daß sie mit Drehmomenten­ aufzeichner versehen sind, die nach einer vorgegebenen Stromaufnahme die Gewinnungswerkzeuge heben oder senken, d.h. vom Gestein weg in den Kohlebereich sich selbsttätig regelnd eintauchen lassen.Method for controlling coal extraction machines, characterized in that they are provided with torque recorders which raise or lower the extraction tools according to a predetermined current consumption, that is to say they can be automatically immersed in the coal region away from the rock.
