摘要： The invention relates to a method for introducing a vertical shaft (4) underground (2) and to a shaft driving machine (1) set up particularly for performing the method, wherein a cutting wheel (17) is rotated solely about a horizontal axis until a penetration trough (43) having a predetermined penetration depth is formed, and the cutting wheel is then also rotated about a central vertical axis until a shaft foot (3) is dug out to the penetration depth. A relatively high sinking rate is thereby achieved for the shaft (4).

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.

摘要： In the case of a method and a device for transporting overburden away during tunnelling, a seal (27) that separates a first portion and a second portion of a transporting screw arrangement (19, 31) is provided. As a result, in open tunnelling or in earth-pressure-assisted tunnelling, when the seal (27) is closed, overburden can be transported out of a first opening (22), arranged ahead of the seal (27) in the direction of removal, whereas, when the first opening (22) is closed and the seal (27) is open, the overburden can be transported into the second portion in fluid-assisted tunnelling.
