Die Erfindung betrifft weiterhin ein Verfahren zum Abbau von Gestein mit einer Vortriebs- und Lademaschine, bei welchem mit mindestens einem Anbauarbeitsgerät, das an einem verstellbaren Ausleger der Vortriebs- und Lademaschine wechselbar befestigt ist, Gestein abgebaut wird, das abgebaute Gestein von einem Ladetisch aufgenommen wird, welcher an einem Frontbereich des Fahrwerks der Vortriebs- und Lademaschine angeordnet ist, und das abgebaute Gestein von dem Ladetisch mittels einer Fördereinrichtung über das Fahrwerk zu einem Heckbereich des Fahrwerks gefördert wird, gemäß dem Oberbegriff des Anspruchs 12.The invention further relates to a method for mining of rock with a propulsion and loading machine, in which with at least one cultivation implement, which is removably attached to an adjustable boom of the propulsion and loading machine, rock is mined, the mined rock is picked up by a loading table , which is arranged on a front region of the chassis of the propulsion and loading machine, and the mined rock is conveyed from the loading table by means of a conveyor via the chassis to a rear region of the chassis, according to the preamble of

Üblicherweise ist es bei diesen bekannten Vortriebs- und Lademaschinen üblich, dass Reste von abgebautem Gesteinsmaterial in aufwändiger Weise mit dem Tieflöffel auf den Ladetisch geschaufelt werden müssen. Derartige Nacharbeiten zum Sauberladen von Ortsbrust und Stößen sind zeit- und kostenaufwändig.Usually, it is common in these known tunneling and loading machines that remains of mined rock material must be shoveled in a complex manner with the backhoe on the loading table. Such reworking to clean the face and bumps are time consuming and costly.
Der Erfindung liegt die Aufgabe zugrunde, eine Vortriebs- und Lademaschine und ein zugehöriges Verfahren anzugeben, mit denen ein besonders effizienter Betrieb ermöglicht wird.The invention has for its object to provide a propulsion and loading machine and an associated method with which a particularly efficient operation is possible.
Die Aufgabe wir zum einen durch eine Vortriebs- und Lademaschine mit den Merkmalen des Anspruchs 1 und zum anderen durch ein Verfahren zum Abbau von Gestein mit den Merkmalen des Anspruchs 12 gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den jeweils abhängigen Ansprüchen angegeben.The object we achieved on the one hand by a propulsion and loading machine with the features of claim 1 and on the other hand by a method for the degradation of rock with the features of
Die erfindungsgemäße Vortriebs- und Lademaschine ist dadurch gekennzeichnet, dass ein Auslegerarm eine Parallelogrammanordnung von Hebeln aufweist, wobei zumindest ein erster Hydraulikzylinder zur Horizontalverstellung und zumindest ein zweiter Hydraulikzylinder zur Vertikalverstellung vorgesehen sind, und dass zumindest ein bogenförmiger Tragarm an der Parallelogrammanordnung angelenkt ist, wobei an einem distalen Ende des Tragarms das Anbauarbeitsgerät angebracht ist.The propulsion and loading machine according to the invention is characterized in that a cantilever arm has a parallelogram arrangement of levers, wherein at least a first hydraulic cylinder for horizontal adjustment and at least a second hydraulic cylinder are provided for vertical adjustment, and that at least one arcuate support arm is articulated to the parallelogram, wherein a distal end of the support arm, the attachment is attached.
Ein Grundgedanke der Erfindung besteht darin, die Bewegungsfunktionalität des Auslegerarms auf verschiedene Baugruppen zu verteilen. Die Parallelogrammanordnung von Hebeln kann über einen ersten Hydraulikzylinder im Wesentlichen horizontal verstellt werden. Die Horizontalverstellung hat dabei keinen oder nur einen relativ geringen Einfluss auf die sonstige Ausrichtung des Anbauarbeitsgerätes.A basic idea of the invention is to distribute the movement functionality of the extension arm to different assemblies. The parallelogram arrangement of levers can be adjusted substantially horizontally via a first hydraulic cylinder. The horizontal adjustment has no or only a relatively small effect on the other orientation of the attachment.
Ein weiterer Aspekt der Erfindung besteht darin, dass eine Vertikalverstellung des Anbauarbeitsgerätes durch einen bogenförmigen Tragarm erreicht wird, welcher an der Parallelogrammanordnung angelenkt ist. Über den zweiten Hydraulikzylinder an der Parallelogrammanordnung kann der bogenförmige Tragarm so verstellt werden, dass eine im Wesentlichen vertikale Verstellung des Anbauarbeitsgerätes unabhängig von der Position der anderen Baugruppen des Auslegerarms erreicht wird. Hierdurch wird es für einen Maschinebediener relativ leicht möglich, etwa eine mit Gesteinsmaterial gefüllte Schaufel zuverlässig im Raum zu verfahren.Another aspect of the invention is that a vertical adjustment of the cultivation implement is achieved by an arcuate support arm, which is articulated to the parallelogram. About the second hydraulic cylinder on the parallelogram, the arcuate support arm can be adjusted so that a substantially vertical adjustment of the cultivation implement is achieved regardless of the position of the other assemblies of the boom. As a result, it is relatively easy for a machine operator to reliably move a bucket filled with rock material, for example, in space.
Die erfindungsgemäße Vortriebs- und Lademaschine ist dadurch vorteilhaft weitergebildet, dass ein Anbauarbeitsgerät als eine Schaufel mit nach oben und vom Fahrwerk weg gerichteter Schaufelöffnung zum Aufnehmen abgebauten Gesteins ausgebildet ist, dass die Schaufel zumindest eine erstes Schaufelteil und ein zweites Schaufelteil aufweist, welche zum Bilden einer nach unten gerichteten Auswurföffnung aufklappbar miteinander verbunden sind, und dass der Auslegerarm zum Positionieren und Aufklappen der Schaufel über dem Ladetisch ausgebildet ist.The propulsion and loading machine according to the invention is advantageously further developed in that a cultivation implement is designed as a blade with upward and away from the landing gear blade opening for receiving degraded rock, that the blade has at least a first blade portion and a second blade portion, which for forming a downwardly directed ejection opening are hinged together, and that the cantilever arm is designed for positioning and unfolding the blade over the loading table.
Ein Vorteil liegt darin, eine Schaufel mit nach oben gerichteter Schaufelöffnung vorzusehen, wie diese etwa bei Radladern bekannt ist. Mit einer derartigen Schaufel, die auch als Hochlöffel bezeichnet wird, können zuverlässig relativ große Mengen Gesteins aufgenommen werden. Das Gestein kann dabei durch die Baggerschaufel selbst gelöst worden sein oder durch einen vorausgegangenen separaten Lösevorgang, etwa einer Sprengung oder einem Abtragen durch einen Anbau-Hydraulikhammer oder eine Anbau-Fräse. Der Begriff des Anbauarbeitsgerätes ist im Sinne der Erfindung breit zu verstehen, und umfasst ein Aufnehmen von gelöstem Gestein unabhängig davon, wie das Gestein gelöst worden ist, aber auch andere Geräte, welche etwa zum Auftragen von Spritzbeton dienen.One advantage is to provide a blade with upwardly directed blade opening, as is known for wheel loaders. With such a blade, which is also referred to as a high-bucket, relatively large quantities of rock can be reliably absorbed. The rock may have been solved by the excavator bucket itself or by a previous separate dissolution process, such as a blast or a removal by an attached hydraulic breaker or a mounted tiller. The term "growing implement" is to be understood broadly within the meaning of the invention, and includes picking up of dissolved rock, regardless of how the rock has been released, but also other devices which serve for example for applying shotcrete.
Weiterhin weist die Schaufel zumindest zwei Schaufelteile auf, welche in einem oberen Bereich klappbar miteinander verbunden sind. In einer ersten Betriebs- und Aufnahmeposition sind die beiden Schaufelteile zusammengeklappt und bilden einen geschlossenen Schaufelboden. In dieser ersten Betriebsposition kann eine relativ große Menge Gesteinsmaterial aufgenommen werden. Die gefüllte Schaufel kann in dieser ersten geschlossenen Betriebsposition mit dem Auslegerarm über den Ladetisch bewegt werden. In dieser Position kann dann ein Aufklappen der beiden Schaufelteile erfolgen, so dass eine nach unten gerichtete Auswurföffnung an der Schaufel gebildet ist. Somit kann das aufgenommene Gestein aus der Schaufel von oben gezielt auf den Ladetisch fallen und über eine Fördereinrichtung von dort über das Fahrwerk der Vortriebs- und Lademaschine hinweg zu einem Heckbereich transportiert werden. Die Schaufel kann auch als ein Hochklapplöffel und untergriffiges Ladesystem bezeichnet werden.Furthermore, the blade has at least two blade parts, which are hinged together in an upper region. In a first operating and receiving position, the two blade parts are folded and form a closed blade bottom. In this first operating position, a relatively large amount of rock material can be absorbed. The filled bucket can be moved in this first closed operating position with the boom over the loading table. In this position, a folding of the two blade parts can then take place, so that a downwardly directed ejection opening is formed on the blade. Thus, the recorded rock from the bucket targeted fall from the top of the loading table and a conveyor from there on the chassis of the propulsion and Loading machine are transported away to a rear area. The bucket may also be referred to as a flip-top bucket and under-hook loading system.
Durch diese Anordnung kann abgebautes Gestein durch die Vortriebs- und Lademaschine sehr schnell und zuverlässig aufgenommen und von der Ortsbrust abgefördert werden. Das aufwendige Sauberladen von Ortsbrust und Stößen kann bei der erfindungsgemäßen Vortriebs- und Lademaschine entfallen oder zumindest in ganz erheblichem Maße reduziert werden. Die erfindungsgemäße Maschine ist insbesondere zum Betrieb in engen Tunnels und Bergwerkstrecken, vorzugsweise zum Auffahren zum Auffahren von Strecken oder zum Durchbau von strecken bei nachgewachsenem, durch Gebirgsdruck hereinquillendem Gebirge vorgesehen.By this arrangement, mined rock can be picked up very quickly and reliably by the propulsion and loading machine and transported away from the working face. The complex clean loading of working face and joints can be omitted in the propulsion and loading machine according to the invention or at least reduced to a very considerable extent. The machine according to the invention is intended in particular for operation in narrow tunnels and mine routes, preferably for driving on for driving on routes or for the construction of lines in regrowth, by mountain pressure inquillendem mountains.
Eine bevorzugte Ausführungsform der erfindungsgemäßen Vortriebs- und Lademaschine besteht darin, dass an einem Ende des Auslegerarms eine Schwenkeinrichtung zum in Vertikalachse parallelen Verschwenken des Anbauarbeitsgeräts angeordnet ist. Die Schwenkeinrichtung gleicht beim Verschwenken des Auslegerarms durch eine hydraulische Gleichlaufkinematik automatisch die Querbewegungen aus, so dass eine Parallelhaltung des Anbauarbeitswerkzeuges sichergestellt wird. Dies ist insbesondere beim Bohren der Sprenglöcher von besonderer Bedeutung. In einer ausgefahrenen Betriebsposition kann das Anbaubohrgerät vorzugweise parallel zu der Ortsbrust gehalten werden. Die Schwenkeinrichtung kann einen oder mehrere horizontal gerichtete Schwenkzylinder zum Verschwenken aufweisen.A preferred embodiment of the propulsion and loading machine according to the invention is that at one end of the cantilever arm, a pivoting device is arranged for pivoting parallel to the vertical axis of the cultivation implement. The pivoting device compensates automatically for the pivoting of the boom by a hydraulic synchronization kinematics, the transverse movements, so that a parallel attitude of the cultivation tool is ensured. This is especially important when drilling the blast holes. In an extended operating position, the attachment ear device can preferably be held parallel to the working face. The pivoting device may have one or more horizontally directed pivoting cylinders for pivoting.
Eine besonders kompakte Ausbildung des Auslegerarms wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass der Auslegerarm eine Parallelogrammanordnung von Hebeln aufweist. Vorzugsweise kann die Parallelogrammanordnung mit einer Kniehebelanordnung kombiniert sein. Es können auch mehrere Parallelogramm-Mechanismen hintereinander vorgesehen sein, so dass auch ein ziehharmonikaartiges Zusammenfalten des Auslegerarms erreicht werden kann.A particularly compact design of the cantilever arm is achieved according to a development of the invention in that the cantilever arm has a parallelogram arrangement of levers. Preferably, the parallelogram can be combined with a toggle lever assembly. It is also possible to provide several parallelogram mechanisms in succession, so that concertina-like folding of the cantilever arm can also be achieved.
Eine weitere Verbesserung wird nach einer Ausführungsform der Erfindung dadurch erzielt, dass der Auslegerarm drehbar um eine im Wesentlichen vertikale Drehachse auf dem Fahrwerk gelagert ist. Hierdurch wird der Arbeitsbereich des Auslegerarms und damit des Anbauarbeitsgerätes vergrößert.A further improvement is achieved according to an embodiment of the invention in that the cantilever arm is rotatably mounted about a substantially vertical axis of rotation on the chassis. As a result, the working range of the boom and thus the cultivation implement is increased.
Gemäß einer Weiterbildung der erfindungsgemäßen Vortriebs- und Lademaschine ist es besonders vorteilhaft, das in einem Mittelbereich des Fahrwerks ein Drehturm angeordnet ist, welcher zur drehbaren Lagerung des Auslegerarms ausgebildet ist. Durch eine zylindrische Basis mit einem Drehlager wird eine besonders stabile Drehverbindung zwischen dem Auslegerarm und dem Fahrwerk erreicht. Vorzugsweise kann in einem Seitenbereich ein Durchgang für Material und Geräte vorgesehen sein.According to a development of the propulsion and loading machine according to the invention, it is particularly advantageous that in a central region of the chassis a turret is arranged, which is designed for rotatable mounting of the cantilever arm. By a cylindrical base with a pivot bearing a particularly stable rotational connection between the boom and the chassis is achieved. Preferably, a passage for material and equipment may be provided in a side area.
Ein weiterhin kompakter Maschinenaufbau wird nach einer erfindungsgemäßen Ausführungsvariante dadurch erzielt, dass die Fördereinrichtung unter dem Drehturm hindurchgeführt ist. Der Drehturm mit seiner Basis stellt sozusagen eine Brücke über ein Förderband der Fördereinrichtung dar.A still compact machine structure is achieved according to an embodiment of the invention in that the conveyor is passed under the turret. The turret with its base represents, so to speak, a bridge over a conveyor belt of the conveyor.
Eine effiziente Betriebsweise wird gemäß einer Weiterbildung dadurch erreicht, dass an einem distalen Ende des Auslegerarms eine Schnellwechseleinrichtung angeordnet ist, mit der die Anbauarbeitsgeräte lösbar mit dem Auslegerarm verbunden sind. Die Schnellwechseleinrichtung weist dabei Elemente für eine schnelle mechanische Kopplung auf, etwa hydraulisch verstellbare Riegelbolzen. Vorzugsweise kann die Schnellwechseleinrichtung auch elektrische und hydraulische Verbindungselemente aufweisen, welche ein schnelles Lösen und Verbinden elektrischer beziehungsweise hydraulischer Leitungen ermöglichen.An efficient mode of operation is achieved according to a development in that a quick-change device is arranged at a distal end of the cantilever arm, with which the cultivation implements are detachably connected to the cantilever arm. The quick-change device has elements for rapid mechanical coupling, such as hydraulically adjustable locking bolts. Preferably, the quick-change device can also have electrical and hydraulic connection elements, which enable a quick release and connection of electrical or hydraulic lines.
Grundsätzlich kann der Ladetisch am Frontbereich des Fahrwerks ein im Wesentlichen starres plattenförmiges Element sein. Eine bevorzugte Ausführungsform der Erfindung besteht jedoch darin, dass der Ladetisch in seiner Neigung verstellbar ist. Insbesondere kann der Ladetisch aus einer nach unten geneigten Betriebsposition in eine im Wesentlichen horizontale oder eine schräg nach oben gerichtete zweite Betriebsposition verstellt werden, wenn die Schaufel über dem Ladetisch aufgeklappt und das Gestein auf den Ladetisch entleert wird.Basically, the loading table at the front of the chassis can be a substantially rigid plate-shaped element. A preferred embodiment of the invention, however, is that the loading table is adjustable in its inclination. In particular, the loading table can be adjusted from a downwardly inclined operating position into a substantially horizontal or an obliquely upward second operating position when the blade is folded over the loading table and the rock is emptied onto the loading table.
Eine weitere Verbesserung beim Abtransport des abgebauten Gesteins wird nach einer Ausführungsform der Erfindung dadurch erzielt, dass der Ladetisch an seiner Oberseite mindestens ein Förderelement aufweist, mit welchem abgebautes Gestein auf dem Ladetisch zu einer Fördereinrichtung förderbar ist. Förderelemente können vorzugsweise schwenkbare Schieber, drehende Scheiben oder Sterne oder sonstige Zuführelemente sein, welche aktiv abgebautes Gestein auf dem Ladetisch der Fördereinrichtung zuleiten.A further improvement in the removal of the mined rock is achieved according to an embodiment of the invention in that the loading table has on its upper side at least one conveying element with which mined rock on the loading table can be conveyed to a conveyor. Conveying elements may preferably be pivotable slides, rotating disks or stars or other feeding elements, which actively conduct excavated rock on the loading table of the conveyor.
Die Fördereinrichtung zum Fördern des abgebauten Gesteins zum Heckbereich des Fahrwerks kann vorzugsweise ein beliebiger Stetigförderer, insbesondere ein Ketten- oder Bandförderer sein. Eine besonders robuste Ausführungsform wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass die Fördereinrichtung einen Kratzkettenförderer umfasst. Ein Kettenförderer ist dabei mit stegförmigen Mitnehmerelementen versehen.The conveyor for conveying the mined rock to the rear of the landing gear may preferably be any continuous conveyor, in particular a chain or belt conveyor. A particularly robust embodiment is achieved according to a development of the invention in that the conveying device comprises a scraper chain conveyor. A chain conveyor is provided with web-shaped driving elements.
Bei einer weiteren Ausführungsform der Erfindung ist es vorteilhaft, dass die Fördereinrichtung im Heckbereich eine Auswurfeinrichtung zum Abgeben des abgebauten Gesteins an eine Transporteinrichtung aufweist. Dabei kann die Auswurfeinrichtung insbesondere an einem erhöhten Punkt an dem Fahrwerk angeordnet sein. Dies ermöglicht es, beispielsweise einem Muldenkipper, eine Lore, ein Förderband oder ein sonstiges Transportelement unter der Auswurfeinrichtung anzuordnen. Das abgebaute Gestein kann so unmittelbar in die Transporteinrichtung fallen und dann abtransportiert werden. Vorzugsweise ist die Auswurfeinrichtung höhenverstellbar.In a further embodiment of the invention, it is advantageous that the conveyor has an ejection device in the rear region for discharging the mined rock to a transport device. In this case, the ejection device can be arranged in particular at a raised point on the chassis. This makes it possible to arrange, for example, a dump truck, a lorry, a conveyor belt or other transport element under the ejection device. The mined rock can fall directly into the transport device and then be transported away. Preferably, the ejection device is height adjustable.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass der Auslegerarm eine Parallelogrammanordnung von Hebeln aufweist, wobei die Parallelogrammanordnung von zumindest einem ersten Hydraulikzylinder in einer im Wesentlichen horizontalen Richtung verstellt wird, und dass zumindest ein bogenförmiger Tragarm an der Parallelogrammanordnung angelenkt ist und mittels zumindest eines zweiten Hydraulikzylinders in einer im Wesentlichen vertikalen Richtung verstellt wird, wobei an einem distalen Ende des Tragarms das Anbauarbeitsgerät angebracht ist. Die Parallelogrammanordnung besteht vorzugsweise aus zwei im Wesentlichen vertikal gerichteten Hebeln und zwei im Wesentlichen horizontal gerichteten Hebeln, welche jeweils in mehreren Eckbereichen gelenkig miteinander verbunden sind. Es können auch mehrere derartige Parallelogramme aus vier Hebeln nebeneinander zum Bilden der Parallelogrammanordnung angeordnet sein. Der erste Hydraulikzylinder ist einerseits in einem unteren Eckbereich der Parallelogrammanordnung und andererseits an einem gegenüberliegenden vertikalen Hebel für ein im Wesentlichen horizontales Verstellen angeordnet. Der zweite Hydraulikzylinder ist vorzugsweise einerseits an einem oberen Eckbereich der Parallelogrammanordnung und andererseits an einem kurzen Endabschnitt des bogenförmigen Tragarms zu dessen vertikaler Verstellung angelenkt. Dabei ist der zweite Hydraulikzylinder vorzugsweise so gerichtet, dass dieser im Wesentlichen senkrecht auf den zugeordneten Endabschnitt des Tragarms einwirkt.The method according to the invention is characterized in that the cantilever arm has a parallelogram arrangement of levers, wherein the parallelogram arrangement is adjusted by at least one first hydraulic cylinder in a substantially horizontal direction, and that at least one arcuate support arm is articulated to the parallelogram assembly and by means of at least one second hydraulic cylinder is adjusted in a substantially vertical direction, wherein at a distal end of the support arm, the cultivation implement is mounted. The parallelogram arrangement preferably consists of two substantially vertically directed levers and two substantially horizontally oriented levers, which are each connected in an articulated manner in several corner areas. Also, a plurality of such parallelograms of four levers may be arranged side by side to form the parallelogram arrangement. The first hydraulic cylinder is arranged on the one hand in a lower corner region of the parallelogram arrangement and on the other hand on an opposite vertical lever for a substantially horizontal adjustment. The second hydraulic cylinder is preferably articulated on the one hand to an upper corner region of the parallelogram arrangement and on the other hand to a short end portion of the arcuate support arm for its vertical adjustment. In this case, the second hydraulic cylinder is preferably directed so that it acts substantially perpendicular to the associated end portion of the support arm.
Das erfindungsgemäße Verfahren ist vorzugsweise mit einer Vortriebs- und Lademaschine ausführbar, welche zuvor beschrieben worden ist. Es lassen sich dabei entsprechend die vorbeschriebenen Vorteile erzielen.The method according to the invention can preferably be carried out with a propulsion and loading machine which has been described above. It can be achieved according to the advantages described above.
Hinsichtlich des Verfahrens ist die Erfindung dadurch bevorzugt weitergebildet, so dass als Anbauarbeitsgerät eine Schaufel verwendet wird, welche mit einer nach oben und vom Fahrwerk weg gerichteten Schaufelöffnung ausgebildet ist und mindestens ein erstes Schaufelteil und ein zweites Schaufelteil aufweist, welche zum Bilden einer nach unten gerichteten Auswurföffnung ausklappbar miteinander verbunden sind, und dass das abgebaute Gestein in der Schaufel aufgenommen wird, dass die Schaufel mit dem abgebauten Gestein mittels des Auslegerarms in eine Position über dem Ladetisch bewegt wird und dass durch ein Aufklappen der Schaufel das abgebaute Gestein durch die Auswurföffnung nach unten auf den Ladetisch abgegeben wird.With regard to the method, the invention is thereby developed further preferably, so that a bucket is used as an attachment working device, which is designed with a blade opening directed upwards and away from the chassis and has at least a first blade part and a second blade part, which form a downward direction Ejection port are hinged together, and that the mined rock is received in the blade, that the blade is moved with the mined rock by means of the cantilever arm in a position above the loading table and that by unfolding the blade, the mined rock through the discharge opening downwards is delivered to the loading table.
Eine bevorzugte Ausführungsvariante des erfindungsgemäßen Verfahrens besteht darin, dass das abgebaute Gestein von dem Ladetisch mittels der Fördereinrichtung zu einem Heckbereich des Fahrwerks gefördert und an eine Transporteinrichtung abgegeben wird. Mit der Fördereinrichtung wird so das abgebaute Gestein vom Frontbereich zum Heckbereich über das Fahrwerk gefördert. Hierdurch kann die Vortriebs- und Lademaschine auch in engen Tunnels oder Bergwerkstrecken eingesetzt werden.A preferred embodiment of the method according to the invention is that the mined rock is conveyed from the loading table by means of the conveyor to a rear region of the chassis and delivered to a transport device. With the conveyor so the mined rock from the front to the rear area is promoted on the chassis. As a result, the tunneling and loading machine can also be used in narrow tunnels or mine routes.
Gemäß einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens ist es bevorzugt, dass mittels der Transporteinrichtung das abgebaute Gestein von der Vortriebs- und Lademaschine wegtransportiert wird. Die Transporteinrichtung kann dabei ein Muldenkipper oder ein schienengebundenes Transportfahrzeug oder ein kontinuierlicher Bandförderer sein. Entsprechend dem Vortrieb kann dabei die Schieneneinrichtung oder der Bandförderer der Vortriebs- und Lademaschine nachgeführt werden. Insbesondere beim Einsatz einer Schieneneinrichtung kann dabei auch eine nachrückbare Weiche vorgesehen sein, bei welcher schienengebundene Transportfahrzeuge für einen abschließenden Weitertransport in Förderrichtuing umrangiert werden können.According to a further embodiment of the method according to the invention, it is preferred that the mined rock is transported away from the propulsion and loading machine by means of the transport device. The transport device may be a dump truck or a rail-mounted transport vehicle or a continuous belt conveyor. According to the propulsion while the rail device or the belt conveyor of the propulsion and loading machine can be tracked. In particular, when using a rail device can also be provided a nachrückbare switch in which rail-bound transport vehicles can be redeployed for a final onward transport in Förderrichtuing.
