Description

Verfahren zur Anbringung von Geophonen auf hartem Grund und in beliebiger Lage Die Erfindung betrifft ein Verfahren zur Anbringung von Geophonen auf hartem Grund und in beliebiger Lage im Raum bei sprengseismischen Messungen, wenn z. B. bei Messungen unter Tage im Kohlen-oder Eribergbau die Geophone an einer Gesteins wand anzubringen sind. Method of applying geophones on hard ground and in any The invention relates to a method for attaching geophones to hard Ground and in any position in space for seismic explosive measurements, if z. B. when taking measurements underground in coal or heather mining, the geophones on a rock to be attached to the wall.

Bekanntlich verwendet man bei sprengseismischen Messungen über Tag zur Untersuchung des Bodenuntergrundes Geophone mit einem in die Grundplatte eingeschraubten Dorn, der. in den Erdboden eingedrückt, eine ausreichend feste vrbindung zwischen Geophon und Erdboden bewirkt. Auf steinig hartem Erdboden treten hierbei bereits Schwierigkeiten auf. Es ist zwar bekannt. dafür Geophone zu verwenden, deren Dorn mittels eines Gewindes mit dem Geophon verbunden ist. Diese Geophone werden nach Herausschrauben des Domes auf Platten aufgeschraubt, die auf den harten Erdboden aufgesetzt sind. Sind aber z. B. bei Messungen unter Tage im erzbergbau die Geophone an einer Gesteinswand in senkrechter oder beliebig steiler Lage anzubringen. so ist diese bekannte Mehtode nicht mehr anwendbar. In der Praxis ist es in solehen Fällen üblich, kurze Bohrlöcher in das Gestein zu bohren und darin die geophone nach herausschrauben des Domes einzugipsen. Diese Einrichtung hat jedoch den großen Nachteil, daß bei einer üblichen sprengseismischen Messung z. B. mit einer 24spu rigen Apparatur und dreifacher Bündelung 72 Bohrlöcher zu bohren sind, die einen erheblichen Arheits- und Zeitaufwand erfordern und den Arbitsdorfshcritt hemmen. Außerdem werden die Geophone durch das Eingipsen und Weiderausbauen mechanisch strak beansprucht und durch Korrosion angefriffen. As is well known, it is used for seismic explosive measurements during the day for examining the subsurface geophone with a screwed into the base plate Thorn that. pressed into the ground, a sufficiently strong connection between Geophone and soil effects. You are already stepping on stony hard ground Difficulties arise. It is well known. to use geophones for this, their thorn is connected to the geophone by means of a thread. These geophones are after Unscrewing the dome screwed onto plates that lay on the hard ground are put on. But are z. B. the geophones when taking measurements underground in ore mining to be attached to a rock wall in a vertical or any steep position. so this known Mehtode is no longer applicable. In practice it is in such a way In cases it is customary to drill short boreholes in the rock and place the geophone in them to be plastered in after unscrewing the dome. However, this facility has the big one Disadvantage that in a conventional seismic measurement z. B. with a 24spu There are 72 boreholes to be drilled with the same equipment and triple bundling require considerable labor and time and inhibit the Arbitsdorfshcritt. In addition, the geophones become mechanically strong as a result of the plastering and removal of pastures stressed and attacked by corrosion.

Zur Vermeidung dieser Nachteile und als wesentliche Arbeitsverbesserung wird erfindungsgemäß ein Verfahren zur Anbringung von Geophonen auf hartem Grund und in beliebiger Lage im Raum bei sprengseismischen Messungen vorgeschlagen. Das Verfahren besteht darin. daß mittels eines Bolzensetzers ein-Bolzen in den harten Grund eingeschossen und auf dessen herausragenden, in an sieb bekannter ÄVeise mit Gewinde verschenen Kopf ein Geophon aufgeschraubt wird. To avoid these disadvantages and as a significant work improvement According to the invention, a method for attaching geophones to hard ground is provided and in any position in space for seismic explosive measurements. That Procedure is. that by means of a bolt setter a bolt in the hard Ground shot and on its outstanding, in seven well-known ÄVeise with Threaded give away head a geophone is screwed on.

Zur näheren Erläuterung der Erfindung ist in der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes schelmatisch dargestellt und nachfolgend beschrieben. To explain the invention in more detail, an exemplary embodiment is shown in the drawing of the subject matter of the invention presented roguishly and described below.

In der Zeichnung ist in die senkrechte Gelsteinswaild 1 mittels eines Bolzensetzers der Metallbolzen 2 so weit eingeschossen, dlaB noch der mit Gewinde versehenie Bolzenkopf herausragt. Auf den Bolzenkopf ist das Geophon 3 mittels eines Gegengewindes in der Grundplatte des Geophons fest aufgeschraubt. Die Schraubverbindung sichert ein festes Ansitzen des Geophons in der GEstenswand und ist ohne jede Schädigung des Geophons leichter wieder zu lösen. bolzensetzer und Bolzen sind marktübliche werkzeuge. die sich z. B. zum Einschießen von Bolzen in mauerwerk, beton, gewachsenen Fels u. dgl. bewährt haben und in verschiedener Größe und Ausführung lieferbar sind. Die Eindringtiefe des Bolzens läßt sich durch Verwendung verschiedener Patronengrößen regeln. In the drawing is in the vertical Gelsteinswaild 1 by means of a The metal bolt 2 is shot in so far that the one with the thread is still there provided the bolt head protrudes. On the bolt head is the geophone 3 by means of a Counter thread firmly screwed into the base plate of the geophone. The screw connection ensures that the geophone is firmly seated in the rock wall and is without any damage of the geophone easier to loosen again. bolt setters and bolts are standard on the market tools. which z. B. for shooting in bolts in masonry, concrete, waxed Fels and the like have proven themselves and are available in various sizes and designs. The penetration depth of the bolt can be determined by using different cartridge sizes rules.

Das Verfahren gemäß der Erfindung verenfaht und verbilligt die Geophonanbringung in beliebiger Lage und auf harten Grund westilch, es ach den seismischen Meßtrupp unabhängig vom Vorhandensein der für Gesteinsbohrungen erorderlichen Arbeitsmittel und fördert entscheidend den Arbeitsfortschritt. The method according to the invention verenfaht and makes the geophone installation cheaper Westilch in any position and on hard ground, and the seismic survey team regardless of the availability of the work equipment required for rock drilling and decisively promotes work progress.
