Abstract

A process for drilling minerals, rock and the like, using rotating disc machines characterized in that materials to be drilled - if necessary rough cut or stress-relieved, preferably frontally in a direction of propulsion, but also radially outwards - are undercut layer by layer, each layer breaking into the open. The process is used in combination with a self-steering propulsion unit which is supported or guided on or by the previously machined/rough-cut working face so that the depth of undercutting remains constant.

Description

Verfahren zum Bohren von Mineralien System- und ZeichnungsbeschreibungMineral drilling method System and drawing description
Gesteine und besonders Mineralien werden üblicherweise durch Bohren und Schießen abgebaut - mit den bekannten Nachteilen. Mit dem erfindungsgemäßen Verfahren können o.a. Materialien sprengungsfrei, mit optimalem Absprengeffekt - und schichtweise abgetragen werden - vorzugsweise in einer linearen Vortriebsrichtung. Es hat sich gezeigt, daß beim hinterschneidenden in den freien Raum brechenden Gesteinsabtragen der Gesteinsdruck zu wesentlich gröberem Bohrgut verhilft - was u.a. schnelleres und rationelleres Bohren bewirkt; auch die sogenannten Abbohrbreiten bzw. -tiefen können in Abhängigkeit des zu bohrenden Materials erheblich größer gewählt werden.Rocks and especially minerals are usually mined by drilling and shooting - with the known disadvantages. With the method according to the invention, o.a. Materials free of explosions, with optimal blasting effect - and removed in layers - preferably in a linear direction of advance. It has been shown that when undercutting rock is cut away into free space, the rock pressure helps to produce much coarser drillings - which, among other things. faster and more efficient drilling; The so-called drilling widths and depths can also be selected to be considerably larger, depending on the material to be drilled.
Gesonderter Schutz - als Verfahrensanspruch - wird dafür beantragt, mit Scheibenwerkzeugen gemäß Fig. 2 vorzuschützen - ggf. nur oben und unten je ein horizontaler Kalibrier-/ Entspannungsschlitz - und anschließend mit einseitig konischen Disken- oder Scheibenwerkzeugen hinterschneidend abzusprengen / abzutragen.Separate protection - as a procedural claim - is requested to protect with disk tools according to FIG. 2 - if necessary only a horizontal calibration / relaxation slot at the top and bottom - and then to blast off / remove with undercut conical disk or disk tools.
Gesonderter Schutz wird aber auch dafür beantragt, von einem vorhandenen Einbruch oder Vorbohrloch aus mit dem erfindungsgemäßen System auch beliebige Profile von Innen nach Außen zu bohren - z.B. Bogen- bzw. Tunnelprofile - oder Schächte.Separate protection is also requested to drill any profile from the inside to the outside from an existing burglary or pilot hole with the system according to the invention - e.g. Arch or tunnel profiles - or shafts.
Aktivierung von Innen oder Außen bedeutet, daß Disken, Scheiben oder dgl. - mit oder ohne Verzahnung - einerseits im Inneren aktiviert werden können z.B. durch Exzenter, - oder das gesamte Bohrwerkzeug von Außen z.B. durch ein Exzenter- oder Unwuchtschlaggerät beaufschlagt und damit aktiviert wird.Activation from the inside or outside means that disks, disks or the like - with or without teeth - can be activated on the inside, e.g. by eccentric, - or the entire drilling tool from the outside e.g. is acted upon by an eccentric or unbalance impact device and is thus activated.
Das erfindungsgemäße selbstεteuernde Bohraggregat het nicht nur den Vorteil, daß es keine Steuerungεelektronik bzw. keinen Mann zum Steuern benötigt, sondern daß hinter den Bohrwerkzeugen das Bohrgut frei aufgenommen d.h. abgefördert werden kann; dabei können am rotierenden Bohrwerkzeug noch Schaufeln installiert werden - als gesonderter Schutz. In einer Ausführungsform zeigt die Zeichnung 1 unter 1 das hinterschneidende abtragende absprengende drehend gelagerte Disken- oder Scheiben-Werkzeug, -2 ist der drehende oder schwenkbare Arm des Bohrwerkzeuges, -3 die Gesteinskontur vor dem Hinterschneiden und -4 nach dem Hinterschneiden, der Pfeil ist die Vortriebsrichtung.The self-controlling drilling unit according to the invention not only has the advantage that it does not require any control electronics or a man to control it, but that the drilling material can be freely picked up behind the drilling tools, ie can be removed; blades can also be installed on the rotating drilling tool - as separate protection. In one embodiment, the drawing 1 shows under 1 the undercutting, removing, rotating, disc or disc tool, -2 is the rotating or swiveling arm of the drilling tool, -3 is the rock contour before the undercut and -4 after the undercut, which is the arrow the direction of advance.

In Fig. 4 ist 11 eine konventionelle Vorschubeinrichtung und 12 der In dieser Ausführung rotierende Bohrkopf mit mehreren Disken- oder Scheibenwerkzeugen - in einer Linie angeordnet nur eine Schicht hinterschneidend oder nur einen Schlitz bohrend; versetzt angeordnet jedoch mehrfach, hinterschneidend bzw. schlitzend - z.B. gemäß Fig. 5-In FIG. 4, 11 is a conventional feed device and 12 the drilling head rotating in this embodiment with a plurality of disc or disk tools - arranged in a line, undercutting only one layer or drilling only one slot; staggered but multiple, undercutting or slitting - e.g. 5-
In Fig. 5 sind 13 die In mehreren Schichten jeweils hinterschneidenden abtragenden rotierenden - ggf. schlagendenIn FIG. 5, 13 are the rotating rotating, possibly striking, undercut in several layers
- und/oder fräsenden/schneidenden Diskenbohrwerkzeuge,- and / or milling / cutting disc drilling tools,
14 sind Halterungen hierfür und 15 ist die motorisch, angetriebene Welle. Die in Vortriebsrichtung gestuft spaltend arbeitenden Werkzeuge 13 heben ungleich lange Heiterungen, die auf der Welle 15 gleichmäßig verteilt sind - die unten nur gestrichelt dargestellten Werkzeuge haben gleich lange14 are brackets for this and 15 is the motor-driven shaft. The tools 13, which work in stages in the direction of splitting, raise uneven lengths of expansion which are evenly distributed on the shaft 15 - the tools shown only in broken lines below have the same length
- auf der Welle mit 120° versetzt angeordnete Werkzeughalter bzw. Bohrwerkzeuge, um ebenfalls eine Schient nach der anderen abtragen zu können - mit nur einem Aggregat.- Tool holders or drilling tools offset on the shaft with 120 °, so that one slide after the other can also be removed - with only one unit.
In Fig. 6 ist - in einer Sicht von Oben - 16 die Abbaufront bzw. -richtung. In dieser - einer von mehreren möglichen Ausführungsformen - ist 17 die Zugvorrichtung, ein im Hangenden und Liegenden verspannter Hydraulikstempel mit Zugzylinder. 18 ist eine Kufe, die aber auch durch Räder/ Rollen ersetzt - oder von Hub zu Hub angepreßt arretiert werden kann - dann aber unter Verwendung einer gesonderten Hub- / Schub- / Schwenkeinrichtung, 19 ist die Andruckvorrichtung - am hydraulischen Stempel schwenkbar gelagert - siehe Pfeil 20. Mit dieser erfindungsgemäßen Technik kann gemäß Anspruch 10 auch ein selbstfahrendes Raupen- oder Räderfahrwerk verwendet werden - mit einer Vortriebs- und einer Seitenkomponente. D.h. bei Raupenantrieb bringt die äußere Raupe mehr Vortriebsleistung - bei Rädern werden die A.chsen angewinkelt - um die für den Andruck und die Führung erforderliche Seiten Komponente aufzubringen; - hierfür wird gesonderter Schutz beansprucht. Durch 21 ist ein nur einschnittiges Hinterschneid-/Abtragwerkzeug dargestellt, in dieser Ausführungsform - für die gesonderter Schutz beantragt wird - eine auf einem motorisch angetriebenen Exzenter freidrhend gelagerte und dadurch selbständig gegenläufig rotierende schlagend arbeitende einseitig konische Diske, die mit Zähnen oder dgl. versehen - angetrieben fräsend arbeiten kann. Bei der gezeichneten einfachen Ausführung trägt nur ein Diskenbohrwerkzeug die gesamte Abbaufront / -höhe in nur einer Schicht ab. Die oben erklärten Systeme könnennatürlich auch zum Abtragen horizontaler Schichten eingesetzt werden - z.B. zum Abtregen von Strassendecken. - Hierfür wird gesonderter ochutz beantragt.6 - in a view from above - 16 is the dismantling front or direction. In this - one of several possible embodiments - 17 is the traction device, a hydraulic ram clamped in the hanging and lying position with a pull cylinder. 18 is a runner, which can also be replaced by wheels / rollers - or locked from stroke to stroke - but then using a separate lifting / pushing / swiveling device, 19 the pressure device - swivel-mounted on the hydraulic ram - see Arrow 20. With this technique according to the invention, a self-propelled crawler or wheel chassis can also be used - with a propulsion and a side component. In other words, in the case of a caterpillar drive, the outer caterpillar provides more propulsive power - the axles are angled on wheels - in order to apply the components required for pressure and guidance; - separate protection is required for this. 21 shows an undercut / removal tool with only one cut, in this embodiment - for which separate protection is requested - a self-rotating conical disc mounted on a motor-driven eccentric and thus independently rotating in opposite directions, working with teeth or the like - driven milling can work. In the simple design shown, only one disc drilling tool removes the entire excavation front / height in just one shift. The systems explained above can of course also be used to remove horizontal layers - for example to remove road surfaces. - Special protection is requested for this.
Gleichzeitig mit dieser Erklärung der Figur 7 wird ein Verfahrenspatent dafür beansprucht, mit Schneidwerkzeugen 21 in Richtung 22 vorzuschützen - zum Entspannen und/oder Kalibrieren - um dann mit Hinterschneidwerkzeugen 23 in etwa Schlitztiefe und -höhe in einer oder mehreren Schichten abzutragen - z.B. in einer Höhe von etwa 20 - 30 cm um reef selektiv zu gewinnen; mit Abstand dahinter - um das abgetragene Material zuvor abtransportieren zu können - wird z.B. mit den beiden dargestellten Bohrwerkzeugen 24 die obere und untere Restschicht in gleicher Tiefe wie zuvor bis zur Ge samthöhe des 'stope 'von z.B. 1,20 m abgetragen. Alle vorbeschriebenen Schlitz- / Abtragwerkzeuge sind vorzugsweise auf einem (nicht dargestellten) Kaschinenrahmen instruiert, der vorzugsweise erfindungsgemäß an der vorbearbeiteten / vorgeschnittenen Abbaufront geführt wird. In dieser Figur 7 sind die vorschneidenden bzw. abtragenden Werkzeuge 21 und 23 vorzugsweise höhenveränderbar - z.B. um dem reef besser folgen zu können - die nachschneidenden Werkzeuge 24 haben dabei einen größeren als den dargestellten Durchmesser.Simultaneously with this explanation of FIG. 7, a process patent is claimed to protect with cutting tools 21 in direction 22 - for relaxing and / or calibrating - in order to then remove undercut tools 23 in approximately one slot depth and height in one or more layers - for example in one height from about 20 - 30 cm to selectively win reef; at a distance behind it - in order to be able to remove the removed material beforehand - the upper and lower residual layers are cut to the same depth as before using the two drilling tools 24 shown, for example the total height of the 'stop', e.g. 1.20 m. All of the above-described slitting / removal tools are preferably instructed on a machine frame (not shown) which, according to the invention, is preferably guided on the pre-processed / pre-cut removal front. In this FIG. 7, the pre-cutting or ablating tools 21 and 23 can preferably be adjusted in height - for example in order to be able to follow the reef better - the re-cutting tools 24 have a larger diameter than the one shown.
Figur 8 erklärt noch einmal Figur 7, wobei 25 wieder das vorschneidende - 26 das hinterschneidende und 27 die das Nebengestein abtragenden Werkzeuge sind. 26 kenn auch schwenk- und/oder verfahrbar angeordnet werden - womit die Werkzeuge 27 entfallen könnten. 28 ist die Kontur der ursprünglichen Abbaufront. Gesonder Schutz wird dafür beantragt, bei den erfindungεgemäßen Systemen des Schützens, Hinterschneidens und dgl. nur den aktiven vorderen Schneidradius άan der Wandung anliegen zu lassen d.h. durch einen geringen Sehneidwinkel die hintere Seite der Bisken- oder Schneidwerkzeuge nicht an der Wandung unnütz schleifen bzw. verschleißen zu lassen, siehe Figur 6, Werkzeug 21. Mit 21a ist gestrichelt eine Werkzeuganordnung dargestellt, mit der ein zweiter, dritter etc. Abtrag in einem Arbeltsgang erfolgen kann - für diese Werkzeugenordnung wird gesonderter Schutz beantragt - auch für die Anwendung dieser Technik auf pendelnd -bzw. rotierend abeitenden Schneidwerkzeugen gemäß Figur 3 -7- und -8- bzw. Figur 4 -12-.FIG. 8 explains FIG. 7 again, 25 again being the pre-cutting tool - 26 the undercutting tool and 27 the tool removing the bedrock. 26 can also be arranged so that they can be swiveled and / or moved - with which the tools 27 could be dispensed with. 28 is the contour of the original mining front. Special protection is requested for the inventive systems of protection, undercutting and the like, to only allow the active front cutting radius to rest on the wall, i.e. not to uselessly grind or wear the rear side of the bisque or cutting tools on the wall due to a small cutting angle, see FIG. 6, tool 21. A tool arrangement is shown in dashed lines at 21a, with which a second, third, etc. removal can be carried out in one Arbeltsgang can take place - special protection is requested for this tool order - also for the application of this technique on pendulum-or. rotating cutting tools according to Figure 3 -7- and -8- or Figure 4 -12-.
