ABSTRACT:
The apparatus for excavating passages such as tunnels, shafts and the like, is continually and/or intermittently movable in a predetermined driving direction and contains at least one boring head, possibly, a multipart boring head. In its operative position, the boring head substantially covers the cross-section of the passage to be excavated. The boring head is constructed so as to be thrust or pressed by means of fluid-operated cylinders, tooth racks or the like against the face to be excavated. The apparatus possesses one or a number of drive units for the boring head and at least one device for removing the excavated material. There are further provided a support device for supporting the boring head in the passage and at least one drilling mount possessing a bore motor and a thrust motor for drilling anchor holes and/or blast holes and/or for placing anchors transversely to a predetermined driving direction. When viewed in the driving direction, the drilling mount is located forwardly of the boring head, preferably between the boring head support device and the boring head. At least one, if desired, two drilling mounts possessing a bore motor and a thrust motor, mounted at a carrier which can be rotationally and positionally fixed substantially relative to the driving direction, especially substantially relative to the passage lengthwise axis. Preferably the drilling mounts are pivotable and/or displaceable in a drilling direction defined by the drilling mounts, especially by means of fluid-operated cylinders.
