Definitions
- the invention relates to a method for driving and expanding an underground route, in which the tunnel face is dismantled with a tunnel boring machine with a cantilever arm that can be pivoted at least vertically with removal tools, and route extension elements are transported and set with a device that can be moved on the existing upgrade a tunnel boring machine for performing the method with a cantilever arm that can be pivoted at least in the vertical direction.
- a partial cutting machine with a boom arm that can be pivoted on all sides with a cutting head is used and the face is alternately removed and then, when the partial cutting machine is at a standstill, the extension is set by a track extension device that can be moved on the existing extension.
- the expansion elements essentially consist of a cap element and laterally adjoining the cap element supporting elements which rest on the sole.
- a disadvantage of this known combination of a partial cutting machine with a section extension machine is the fact that the expansion can only be carried out when the section cutting machine is at rest, since in order to manipulate the elements of the section extension device, the cantilever arm with the removal tools must be completely lowered to the sole in order to have a corresponding one Ensure free space for placing the expansion elements.
- a similar combination of a partial cutting machine with a device for transporting and setting track extension elements can also be found in DE- ⁇ S 25 58 647.
- a manipulator for pre-attachment on the cantilever arm, which carries the removal tools is provided, so that even in this embodiment, the face cannot be further removed while the removal elements are being inserted.
- the invention now aims to provide a method for driving and expanding an underground route, in which expansion elements can be introduced, pledged and set right up to the face even during the operation of a route driving machine, so that for the setting of the expansion elements an interruption of the tunneling work is largely not necessary.

- the removal elements adjoining the base are braced with pre-attached caps, so that completed arches extend into a section are present, which extends to the front end of the tunnel boring machine.
- further cap elements of the route expansion are pre-found up to immediately on the working face, from which it follows that all removal work is carried out during the dismantling process of the lower working area of the working face.
- the tunnel boring machine is thus advanced in the direction of the face and appropriately braced or anchored, whereupon the upper part of the face can be dismantled immediately afterwards. There is thus a complete parallelization of the dismantling and expansion work, so that downtimes of the tunnel boring machine for inserting the expansion elements can be largely avoided.
- the preferred procedure is to select the dividing line between the upper and lower part of the orb breasts below the stage of the device for setting and transporting the removal elements .
- the preferred procedure is that before the tunnel boring machine is positioned for a new mining operation, a sole cut is made directly on the sole whose depth corresponds to at least a quarter of the total mining depth of a mining operation.
- This makes it possible, before the start of the dismantling process in the upper part of the working face, to bring the line driving machine or the loading ramp directly to the working face, in order to enable the removed material to be removed safely during the entire dismantling process.
- the tunnel boring machine is advantageous Move into the sole incision and clamped in this position.

- the cantilever arm can be telescoped and / or the bearing of the cantilever arm can be displaced relative to the frame of the tunnel boring machine, it is possible to dismantle a correspondingly deep upper part of the face, whereupon the dismantling tools are shortened accordingly Cantilever arm or a shifting of the support of the cantilever arm in the direction away from the working face into a position in which the lower part of the working face can be removed.
- a displaceable mounting of the cutting boom relative to the frame of the cutting machine and to the loading device can be implemented in a simple manner by means of a longitudinally displaceable slide for the swivel mechanism. The use of operating personnel is practically indispensable, in particular for introducing the lateral expansion elements adjoining the sole.
- the training is preferably carried out in such a way that the machine for the tunnel boring machine facing side of the loading device are arranged at least over a portion of the circumference in a substantially vertical direction extending deflector plates, in which a: passage opening is provided for the extension arm, wherein according to a particularly preferred embodiment, the deflector plates extend substantially up to the top - Extend edge of the machine frame of the tunnel boring machine.
- deflectors firstly provide effective protection for the operating personnel working directly behind them when the removal elements are set.
- the loading device has adjustable, in particular hydraulically adjustable, side parts, as a result of which the charging device is securely braced in the sole cut.
- the design is such that the baffle plates or partition elements carry, at their ends adjacent to the front end of the loading device, further pivotable baffle plates which are pivoted beyond the lateral limitation of the loading device, whereby particularly simple bracing is achieved.
- the deflecting plates or partition elements which can be extended laterally extend in the extended position over the width

- FIGS. 1 to 7 generally 1 denotes a tunnel boring machine which can be moved by means of a crawler chassis 2.
- a boom arm 3, which can be pivoted at least in the vertical direction, is mounted on the tunnel boring machine and carries removal tools, such as cutting heads 4.
- a loading device 5 is used to hold the dismantled material, which has baffles 7 on its rear side facing the tunnel boring machine, ie facing away from the face 6, the upper edge 8 of which essentially extends up to the upper edge 9 of the frame of the tunnel boring machine or the storage of the Cantilever arm 3 is sufficient.
- the material picked up by the loading device 5 is conveyed away via a schematically indicated conveyor 10.
- a device, generally designated 11, for setting and transporting removal elements is provided, this device 11 being movable on a track or rail 13 fixed to existing removal elements 12.
- Fig.l shows the state immediately before the start of a new dismantling process.
- the cutting arm 3 with the removal tools 4 is in its raised position, in which a cutting takes place.
