摘要： The drilling tool is adapted for being releasably mounted to the lower end of a rod string (20) of a drilling rig (30) and comprises a container (2) having a cylindrical or truncated-cone shape fitted at its lower end with a plurality of cutting tools or cutters (10) for crushing rock.
The drilling tool (1) further comprises:

a plate (3) for releasably retaining a plurality of modular elements (14) forming a load (13); and
curved blades (9), located proximate to the cutting tools (10), adapted for conveying rock spalls into the container (2) through suitable apertures (8) in the bottom of the container (2).
The cutting tools (10) are mounted to a plurality of radial plates (7) securely fixed proximate to the bottom edge of the container (2). The curved blades are welded to the edges of the radial plates (7), the concavity of each blade (9) being arranged facing the direction of rotation of the drilling tool (1).

摘要： The invention relates to a device for excavating a shaft (1) in which a suction line (6) extends between a mining tool (2, 3) and a single intermediate storage container (7). During the continuous operation of the mining tool (2, 3), the intermediate storage chamber (7) can be filled via the suction line (6) to a predetermined filling level, and when said level is reached, in the event of a lack of pressure in the suction line (6), an ejector door (26) can be opened to fill at least one of the conveyor containers (28). Based on the arrangement of the opening area of the suction line (6) in the immediate vicinity of the mining tool (2, 3), the degraded material produced when there is no pressure in the suction line (6) can be easily evacuated after restarting the suction line (6). This enables a high degradation performance to be obtained.
