Description
Verfahren zum Ausspülen von verdämmten Bohrlöchern. Es ist bekannt, daß das Aufbohren von verdämmten Bohr- bzw. Sprenglöchern in Bergwerken, Steinbrüchen usw. im Falle von Fehlschüssen zweckmäßig durch ein Spülverfahren bewirkt wird, indem Preßluft oder Prcßwasser in dünnem Strahl auf das Verdämmungsmaterial aufgeschleudert wird.Method for flushing out blocked boreholes. It is known, that the drilling of blocked drill holes or blast holes in mines, quarries etc. in the case of missed shots is expediently effected by a flushing process, by hurling compressed air or water in a thin jet onto the damming material will.
Es hat sich nun durch Versuche gezeigt, daß dieser Vorgang durch eine geeignete Wirbelbewegung des Preßmediums, beispielsweise des Wassers, besonders beschleunigt wird. Zu diesem Zweck kann das in das Bohrloch eintretende Wasser in mehrere unter spitzem Winkel schräg auf das Verdämmungsmaterial auftretende Strahlen zerlegt werden, die nach Aufwühlen des Besatzes vereinigt nach außen abgeleitet werden. Durch die in gleichem Sinne arbeitenden Einzelstrahlen wird eine regelmäßige Wasserbewegung eingeleitet, so daß eine Stauung des Verdämmungsmaterials vor dem auftretenden Strahl oder eine Stauung in der Ableitung der aufgeschwemmten Massen mit Sicherheit vermieden werden kann. Die Erzeugung des Wirbelstrahles geschieht vorteilhaft in einer Düse, deren Bohrungen gegenüber der Achse des Bohrloches windschief und divergierend oder konvergierend angeordnet sind. Zweckmäßig ist es dabei, den Abfluß des Arbeitswassers und den Auswurf des aufgelockerten Materials durch ein besonderes Leitrohr zentral vorzunehmen. Die Vorrichtung zur Erzeugung des Wasserwirbels bzw. zur Trennung des Druckwassers in mehrere Einzelstrahlen kann entweder an der Mündung des Bohrloches fest angebracht sein oder in däs Bohrloch hineingeführt werden, je nach dem Fortschritt der erreichten Ausspülarbeit.It has now been shown through experiments that this process by a suitable vortex movement of the pressing medium, for example the water, in particular is accelerated. For this purpose, the water entering the borehole can be in several rays appearing obliquely on the damming material at an acute angle are dismantled, which are united after the trimmings have been churned up and discharged to the outside will. The individual rays working in the same sense become a regular one Water movement initiated, so that a stowage of the damming material before occurring jet or a congestion in the discharge of the floating masses can be avoided with certainty. The vortex jet is generated advantageous in a nozzle whose bores are skewed relative to the axis of the borehole and are arranged diverging or converging. It is useful to use the Drainage of the working water and the ejection of the loosened material through a special guide scope to be carried out centrally. The device for generating the water vortex or to separate the pressurized water into several individual jets, either at the The mouth of the borehole be firmly attached or guided into the borehole, depending on the progress of the rinsing work achieved.
