Description

Sprengpatrone zum Hohlraumschießen Die Erfindung betrifft eine Sprengpatrone zum Hohlraumschießen, die an ihrer Innenfläche mit Führungsrippen, -wellen o. dgl. versehen ist, die den Patronenkörper gegen die Bohrlochwandung so abstützen, daß an verschiedenen Stellen freie Räume verbleiben. Durch diese Ausbildung des Patronenkörpers wird erreicht, daß um die Patrone herum zwischen Patrone und Bohrlochwandung gleichmäßig verteilte kleinere Hohlräume entstehen, durch die die Leistung der detonierenden Sprengpatrone wesentlich erhöht wird.Explosive cartridge for cavity shooting The invention relates to an explosive cartridge for cavity shooting, which on its inner surface with guide ribs, shafts o. The like. is provided, which support the cartridge body against the borehole wall so that Free spaces remain in various places. Through this training of the cartridge body it is achieved that evenly around the cartridge between cartridge and borehole wall distributed smaller cavities arise through which the performance of the detonating Explosive cartridge is increased significantly.

Sprengpatronen mit einer gewellten Außenfläche oder einer wellenförmigen Schicht, die zwischen Patrone und Bohrlochwandung kommt, sind zwar an sich bekannt. Bei den bekannten Patronen handelt es sich aber um Patronen zum Sprengen mit flüssiger Luft. Die dort vorgesehene Zwischenlage hat die Aufgabe, die Sprengluftpatrone gegen die «arme Bohrlochwandung zu isolieren. Würde die Sprengluftpatrone an der Bohrlochwandung satt anliegen, so würde selbstverständlich die Luft sehr schnell verdunsten. Bei den bekannten Patronen handelt es sich also um die Isolation, beim Gegenstand der Erfindung dagegen um die Schaffung von Hohlräumen.Explosive cartridges with a corrugated outer surface or a corrugated one The layer that comes between the cartridge and the borehole wall are known per se. The known cartridges are, however, cartridges for blasting with liquid Air. The intermediate layer provided there has the task of counteracting the explosive air cartridge to insulate the poor wall of the borehole. Would the explosive air cartridge on the borehole wall if you were full, the air would of course evaporate very quickly. at the well-known cartridges it is about the insulation, the subject of the Invention, however, to the creation of cavities.

Die Führungsrippen, -wellen o. dgl. können auf verschiedene Weise hergestellt werden. Entweder wird um den zylindrischen Sprengkörper eine Lage aus gewelltem Stoff, z. B. starker Wellpappe, derart herumgelegt, daß die Rillen nach außen gerichtet sind. Selbstverständlich kann die gewellte Umhüllung aber auch mit den Erhöhungen nach- innen um die Patrone gelegt werden. Gegebenenfalls kann bereits beim Herstellen der Patrone von vornherein. eine gerippte oder gewellte Manteloberfläche vorgesehen werden. Hierzu wird die Patrone nicht aus einer glatten Matrize gepreßt, sondern aus einer im Innern mit 'Rippen versehenen Matrize, so daß die Patrone Längsrillen aufweist.The guide ribs, shafts or the like can be in various ways getting produced. Either a layer is made around the cylindrical explosive device corrugated fabric, e.g. B. strong corrugated cardboard, laid around in such a way that the grooves after are directed outside. Of course, the corrugated envelope can also be the elevations inwards around the cartridge. If necessary, can already when manufacturing the cartridge from the start. a ribbed or corrugated jacket surface are provided. For this purpose, the cartridge is not pressed out of a smooth die, but from a die with ribs inside so that the cartridge has longitudinal grooves having.
