In a device and a method for continuously driving a tunnel along a desired setpoint trajectory there is provision to influence pressing forces which are applied to installed tubbing segments by compactors using a control circuit, wherein, during the driving and during the installation of tubbing rings, an actual trajectory of the device remains in a region which is permissible for maintaining the desired set point trajectory.

Device and method for continuously driving a tunnel

A device for advancing a cavity in underground mining, including a rotary drive, an axial shaft that is rotatable together with the rotary drive about a longitudinal axis, exactly one extraction drum that is rotatable about an drum rotational axis, and a connecting arrangement which is connected to the axial shaft and which supports the extraction drum, the connecting arrangement being configured in such a way that the drum rotational axis and the longitudinal axis lie in a plane, and are oriented at an acute angle with respect to one another in the advancing direction, in all operating positions during the advancement, characterized in that the extraction drum extends over at least an effective radius of the device in the radial direction of the device during advancement of the cavity.

Apparatus and method for driving a cavity in mining

A roller cutter arrangement for a cutting wheel of a tunnel boring machine, including an interchangeable cup, a bearing block which is supported in the interchangeable cup in such a way that it is displaceable along a displacement axis, and a cutting roller unit having at least one cutting roller, which is rotatably supported in the bearing block and which acts along a working axis. The working axis is angled with respect to the displacement axis, so that cutting rollers of the cutting roller units may be situated in close proximity to one another, in particular in the central area of the cutting wheel.
