Description

Verfahren und Vorrichtung zum ßpalten von vorzugsweise hartem Mineral, wie beispielsweise Gestein. Die Erfindung bezieht> sich auf ein Verfahren und eine Vorrichtung zum Spalten von vorzugsweise hartem Mineral wie beispielsweise Gestein, n sQ!Qlie A- r -rbeiten sind bisher verschiedenartige Arbeitsgeräte ei -.ngesetzt worden> so beispielsweise Aufbruchhä=-er.Method and device for splitting preferably hard mineral, such as rock. The invention relates> to a method and an apparatus for the splitting of preferably hard mineral such as rock, n sQ! Qlie A- r -rbeiten heretofore -.ngesetzt various tools ei> such as Aufbruchhä = -er.

Die vorliegende Erfindung will demgegenüber einen Ganz neuen Weg zum Zertrennen und Abspalten von harten Gesteins-. schichten weisen und sQhlUgt aus diesem Grunde vor, daß das zu spaltende TIffineral mit einem.oder mehreren Bohr-löchern versehen wird, in äas eine vorzugsweise hydraulisch- arbeitende Zugvorrichtüng mit einem könischexi sich zum -Bo hrloch -hin erweiternden Zapfen hineinreicht und zwischen 4em Zapfen und der Bohrlochwandung entgegengesetzt konisch ausgebildete Futterstücke angeordnet werden, Die entsprechende Vorrichtung zur Durchführung des erfixidungsgemäßen Verfahrens wird gekennzeichnet dubch ein hydraulisches Z,ugger,ä.t, das mit einem konißchen Zapfen in das Bohrloch greiftl wobei zwischen dera konißclien Zapfen und der Bohrlochwandung entgegengesetzt konisch ausgebildete Futterstücke angeordnet sind. Dabei ist es von Vorteil, daß die Futterstücke an.ihren, der BohrIochwandung zugewandten Flächen mit reibungserhöhenden Ausbildüngen, wie Aufrauhung, reibungserhÖhende Auflagen bder dergleichen, versehen sind. Die Erfindung wird anhand einer schematischen Zeichnung, die nur ein beliebiges AusfÜhrungsbeispiel zeigt, näher erläutert. An'dem mit 2 bezeichneten Hydraulikzugggrät ist der zentrisch im Bohrloch 1 angeordnete konische Zapfen..4.eingeführt, wobei-zwischen dem konischen Zapfen und der Bohrlochwandung entgegengesetzt konisch ausgebildete Futterstücke 5 eingebracht sind. The present invention, however, wants a completely new way of cutting and splitting hard rock. layers indicate and for this reason it is necessary that the tiffineral to be split is provided with one or more boreholes, in which a preferably hydraulic pulling device extends with a pin widening towards the borehole and between four pins The corresponding device for carrying out the method according to the invention is characterized by a hydraulic Z, ugger, Ä.t which engages with a conical pin in the borehole, with an oppositely conical between the conical pin and the borehole wall trained chucks are arranged. It is advantageous that the lining pieces on their surfaces facing the wall of the hole are provided with friction-increasing formations, such as roughening, friction-increasing supports or the like. The invention is explained in more detail with the aid of a schematic drawing which shows only one exemplary embodiment. At the hydraulic traction device, denoted by 2, the conical pin 4 arranged centrally in the borehole 1 is introduced, with chuck pieces 5 of oppositely conical design being introduced between the conical pin and the wall of the borehole.
