Abstract

A coal cutting machine supported above a conveyor, and having a rotary cutter (10) as in 2300224, has a dust collection system with a double-walled flexible hood (2) spaced from the cutting face. Thus it forms an enclosed area over the cutting machine. This is connected to the air distributor. Its bottom edge is supported by a flexible screen portion (7) mounted behind the conveyor. The support member (6) for this portion (7) is hollow, with a grid (8) at the top. The part of the flexible portion (7) immediately above the grid has suction openings (9) connected to the suction openings (11) in the hood above. This enables more dust to be collected at a low level, for narrow seams.

Description

Beschreibung und Erläuterung zur Zusatzpatentanmeldung "Verfahren zur Absaugung und Abkleidung für Kohlegewinnungsbetriebe zwischen dem Gewinnungsfeld und dem Fahrfeld zur Staubbekämpfung.Description and explanation of the additional patent application "Procedure for extraction and cladding for coal extraction companies between the extraction field and the driving area for dust control.

Zusatzanmeldung zur Patentanmeldung P 23 oo 224.6 In der Hauptanmeldung, Akenzeichen P 23 oo 224.6, wird ein Verfahren zur Staubbekämpfung in Kohlenflözen mit mechanischer Gewinnung betrieben. Das Verfahren ist gekennzeichnet durch eine Wettermengenteilung zwischen Fahrfeld und Abbaufeld durch ein Trennorgan.Additional application to patent application P 23 oo 224.6 In the main application, Akenzeichen P 23 oo 224.6, is a method for dust control in coal seams operated with mechanical extraction. The procedure is characterized by a Distribution of the amount of weather between the driving field and the excavation field by a separating element.

Erfindungsgemäß wird ausgeführt, das Verfahren in der Form zu erweitern, daß das Trennorgan, das in Verbindung mit dem Fördermittel oberhalb oder hinter der sogenannten Brake angesetzt wird, aus einer elastischen Haut besteht, die doppelwandig ausgeführt ist, wobei zwischen den einzelnen Wänden Rippen, vorzugsweise aufgeblähte Rippen, die einzelnen Wände auf Distanz halten und gleichzeitig die staubhaltigen Wetter durch die flexible Abschirmung, die als saugrohrartiges System dient, von der Kohlenstoßseite eingesaugt werden, wobei gleichzeitig der beim Ausbaurücken entstehende Staub über Strahlgebläse oder dergleichen in die Saugwand über einen Blasstutzen eingeblasen oder angesaugt wird.According to the invention it is carried out to expand the method in the form that the separating element, which is in connection with the conveyor above or behind the so-called brake is attached, consists of an elastic skin that is double-walled is executed, with ribs, preferably puffed up, between the individual walls Ribs that keep the individual walls at a distance and at the same time the dusty ones Weather through the flexible shielding, which serves as a suction pipe-like system, from the coal face side, while at the same time that of the dismantling back resulting dust via jet fan or the like into the suction wall via a The nozzle is blown in or sucked in.

Weiterhin wird erfindungsgemäß vorgeschlagen, die Braken als Hohlbraken (6) auszubilden und die doppelwandige Abschirmhaut zusätzlich über Saugöffner (9), durch Lippendichtungen (11) geöffnet, mit der Gewinnungsmaschine (lo) in begleitenden Kontakt zu bringen, so daß über eine elastisch aufgelagerte Abschirmung (7), die beim Saugen dicht auf den Auflagegittern (8) aufgelagert ist, über die Saugöffner im Bereich der Gewinnungsmaschine eine erhöhte Absaugung erfolgt.Furthermore, it is proposed according to the invention that the brakes be hollow brakes (6) and the double-walled shielding skin additionally about Suction opener (9), opened by lip seals (11), with the extraction machine (lo) to bring into accompanying contact, so that over an elastically supported Shielding (7), which is tightly supported on the support grids (8) during suction, Increased suction takes place via the suction opener in the area of the extraction machine.

Bei niedrigen Flözen kann selbstverständlich nur eine Absaugung unterhalb (7) erfolgen, so daß die Abschirmhaut (2) nicht zusätzlich zur Absaugung herangezogen werden muß oder aber zur Absaugung des Fahrfeldes beim Ausbaurückvorgang allein dient.In the case of low seams, of course, there is only one suction below (7) take place so that the shielding skin (2) is not additionally used for suction must be or alone for the suction of the driving field during the dismantling reverse process serves.

In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: Mit 1: rdie doppelwandige Abschirmhaut mit 2: saufgeblähte Distanzrippen mit 3: -ein Strahlgebläse mit 4: XSaugschlauch mit 5: XAnsaugstutzen an Ausbausystemen zur Absaugung des dort anfallenden Staubes mit 6: -Hohlbrake mit 7: aelastische Abschirmung mit 8: wAuflagegitter für elastische Abschirmung mit 9: =Saugöffner mit lo: 3Gewinnungsmaschine, z.B.
