Description

Im Bergbau werden bereits sogenannte selbsthemmende Wasserbesatzpatronen bei der Sprengarbeit verwandt, deren selbsthemmende Wirkung im Bohrloch davon ausgeht, daß sie eine ganz oder in einem gewissen Abschnitt von einer geraden abweichende Form aufweisen. Das gleiche Ziel soll nun gemäß der vorliegenden Erfindung auf eine einfachere Weise dadurch erreicht werden, daß die Wasserbesatzpatrone einen dem jeweiligen Bohrloch entsprechenden veränderlichen Querschnitt hat, der es ermöglicht, daß die Wasserbesatzpatrone beim Einführen in das Bohrloch sich im Bohrloch den gegebenen Verhältnissen des Bohrloches entsprechend verändern kann und dadurch sich im Bohrloch festhält.So-called self-locking water filling cartridges are already being used in mining related to blasting work, whose self-locking effect in the borehole assumes that it deviates entirely or in a certain section from a straight line Have shape. The same aim is now aimed at according to the present invention Easier way can be achieved in that the water filling cartridge a dem has a variable cross-section corresponding to the respective borehole, which makes it possible to that the water loading cartridge when inserted into the borehole is in the borehole given conditions of the borehole can change accordingly and thereby holds in the borehole.

Erreicht wird dieses gemäß der vorliegenden Erfindung dadurch, daß die Wasserbesatzpatrone über ihre gesamte Länge mit einem keilförmigen Einschnitt versehen ist. In der Zeichnung ist mit A b b. 1 a) die Wasserbesatzpatrone mit keilförmigem Ein.-schnitt vor dem Einführen in das Bohrloch dargestellt. In der Zeichnung ist mit A b b. 2 b) das Bohrloch, und mit e) die in das Bohrloch eingeführte Wasserbesatzpatrone dargestellt.This is achieved according to the present invention in that the water filling cartridge with a wedge-shaped incision over its entire length is provided. In the drawing is A b b. 1 a) the water filling cartridge with wedge-shaped Incision shown before insertion into the borehole. In the drawing is with A b b. 2 b) the borehole, and with e) the water loading cartridge introduced into the borehole shown.

Es ist zu ersehen, daß die Wasserbesatzpatrone sich im Querschnitt verändert und sich dem Bohrloch angepaßt hat und sich dadurch, daß gewisse Spannungen auftreten, im Bohrloch verklemmt. Die Haltekraft einer solchen Wasserbesatzpatrone soll den bisherigen Erfahrungen im Bergbau entsprechend etwa 3 kg betragen. Entsprechend sind auch die Materialbeanspruchungen, die beim Einführen der Wasserbesatzpatrone in das Bohrloch auftreten. Hier ist es möglich, durch Manipulationen der Wandstärke der Wasserbesatzpatronen sich den gegebenen Erfordernissen anzupassen.It can be seen that the water filling cartridge is in cross section has changed and has adapted to the borehole and by the fact that certain tensions occur, jammed in the borehole. The holding power of such a water filling cartridge should be around 3 kg based on previous experience in mining. Corresponding are also the material stresses that occur when the water filling cartridge is inserted occur in the borehole. Here it is possible by manipulating the wall thickness the water filling cartridges adapt to the given requirements.

Es ist selbstverständlich, daß gegenüber dem gezeigten Anwendungsbeispiel noch mehrere Möglichkeiten vorhanden sind, im Querschnitt veränderliche Wasserbesatzpatronen herzustellen, ohne von dem Grundgedanken der Erfindung abzuweichen.It goes without saying that compared to the application example shown There are still several options available, water-filling cartridges with variable cross-section without departing from the spirit of the invention.
