Abstract

Eine Bohrvorrichtung umfasst ein Schneidrad (1), das eine während des Bohrbetriebs der Ortsbrust des abzubauenden Materials zugewandte Stirnseite aufweist. An der Stirnseite des Schneidrads (1) sind an Schneidradarmen (11, 111) eine Vielzahl von Schälmessern (14) angebracht. Zwischen den Schälmessern (14) sind Hochdruckdüsen (15) angeordnet, die während des Bohrbetriebs jeweils einen Flüssigkeitsstrahl mit Hochdruck auf die Ortsbrust richten.

Figure 00000001
A drilling device comprises a cutting wheel (1) which has an end face facing the working face of the material to be mined during drilling operation. A large number of peeling knives (14) are attached to the cutting wheel arms (11, 111) on the end face of the cutting wheel (1). High-pressure nozzles (15) are arranged between the peeling knives (14), each of which directs a liquid jet at high pressure onto the working face during the drilling operation.
