Zusatz zum Patent 302909.Addendum to patent 302909.
Patentiert im Deutschen Reiche vom 2. Dezember 1915 ab. Längste Dauer: 24.JuIi 1928.Patented in the German Empire on December 2, 1915. Longest duration: July 24, 1928.
Die Erfindung betrifft eine Weiterausbildung des durch das Hauptpatent geschützten Verfahrens zum Abfangen und Sichern des Hangenden und der Stöße im Bergbau ohne Stützung von unten und besteht^ darin, daß die vorstehenden Enden der in den festen Gebirgsschichten befestigten Anker durch Zugmittel (Ketten, Seile oder ähnliche Mittel) verbunden werden, die sich gegen die abzufangenden lockeren Gebirgsteile oder die überhängenden Gebirgsschichten anlegen oder durch Spannvorrichtungen gegen sie gepreßt werden. Auf diese Weise wird eine Art wandernder Ausbau geschaffen, der sich vor dem Wegfüllen des Fördergutes leicht einbringen läßt. Das Verfahren eignet sich insbesondere für das Abfangen überhängender Gebirgsschichten.The invention relates to a further development of the method protected by the main patent to intercept and secure the hanging wall and the impacts in mining without support from below and consists ^ in that the protruding ends of the anchors fastened in the solid rock layers by traction means (Chains, ropes or similar means) are connected, which are against the to be intercepted Lay loose parts of the mountain or the overhanging mountain strata or use tensioning devices pressed against them. In this way it becomes a kind of wandering expansion created, which can be easily introduced before filling away the conveyed material. The procedure is particularly suitable for catching overhanging rock layers.
In feste -Teile des anstehenden Gebirges werden ein oder mehrere Bohrlöcher gestoßen, in diese Anker eingelassen und befestigt und die heraushängenden Teile der Anker in geeigneter Weise zum Stützpunkt für den abzufangenden Gebirgsteil gemacht. Man kann dies beispielsweise tun, indem man zu beiden Seiten des abzufangenden Gebirgsteiles je ein Bohrloch in festes Gebirge stößt, in diese beiden Bohrlöcher Anker einbringt und darin befestigt und die aus dem Bohrloch herausragenden · Teile der Anker, welche zu ösen oder Haken ausgebildet sind, mit Ketten, Seilen o. dgl. so verbindet, daß sie sich gegen die abzufangenden losen Gebirgsteile legen. Sollten sich hierbei diese Zugmittel nicht von , vornherein genügend fest gegen das zu stützende Gebirgsstück anlegen, so kann man dies durch Zwischenschalten einer Spannvorrichtung oder durch Eintreiben von Keilen erreichen. One or more boreholes are drilled into fixed parts of the surrounding rock, embedded and fastened in these anchors and the parts hanging out of the anchors in suitable Way made the base for the part of the mountain to be intercepted. One can do this, for example, by going to both Each side of the mountain part to be intercepted pushes a borehole into solid rock two boreholes anchors introduces and fixed therein and the protruding from the borehole Parts of the anchors, which are designed to be loops or hooks, with chains, Ropes or the like connects so that they lie against the loose mountain parts to be intercepted. If this traction device should not be sufficiently tight against the one to be supported from the outset Create a mountain section, this can be done by inserting a jig or by driving in wedges.
Auch kann man durch Zwischenschalten einer entsprechenden, beispielsweise federnden Einrichtung mit Anzeigevorrichtung ein allmähliches Loslösen — »Absetzen« — des zu stützenden Gebirgsstückes zur Warnung für die Belegschaft sichtbar machen.You can also interpose a corresponding, for example resilient Facility with display device a gradual detachment - "settling" - of the to the supporting mountain section as a warning for the workforce.
