摘要： In a cutting wheel (103) for a tunnel boring machine, a tool condition monitoring device is provided to monitor the condition of at least one mining tool (112, 115, 118) during removal of a geological structure present, during tunneling, at the cutting wheel (103) in a tunneling direction. At least one support part (121, 124, 127) is installed separately and at a distance from the or a relevant mining tool (112, 115, 118). In the relevant support part (121, 124, 127), a current conductor element is embedded, which is interrupted in terms of its ability to carry current after a wear limit which is characteristic of the condition of the relevant mining tool (112, 115, 118) has been reached. In this way, the condition of mining tools (112, 115, 118) can be reliably determined during a relatively simple maintenance operation or retrofitting with a support part (121, 124, 127).

摘要： A device for excavating a shaft in which a suction line extends between a mining tool and a single intermediate storage container. During the continuous operation of the mining tool, the intermediate storage chamber can be filled via the suction line to a predetermined filling level, and when said level is reached, in the event of a lack of pressure in the suction line, an ejector door can be opened to fill at least one of the conveyor containers. Based on the arrangement of the opening area of the suction line in the immediate vicinity of the mining tool, the degraded material produced when there is no pressure in the suction line can be easily evacuated after restarting the suction line.

摘要： In a tunnel boring machine with a shield skin (106) extending in a longitudinal direction, a sensor unit (118) for detecting convergences has a number of hydraulic distance sensors (121) equipped with an extendable probe (124) with extension path measurement. By virtue of the distance sensors (121), the distance between the shield skin (106) in the area of the relevant distance sensor (121) and the surrounding rock mass (103) can be detected as a distance value, so that the thickness of an annular gap (115) can be determined. The distance sensors (121) are arranged in the longitudinal direction of the shield skin (106) at a measuring distance which corresponds to a typical ring width of a tubbing (112). A central unit evaluates the distance values of the distance sensors (121) to determine convergences.

摘要： In a cutting tool (106) for a tunnel boring machine, a tool head (115) equipped with at least one wear sensor (315) is present that is detachably connectable to a tool holder (206, 321). A line arrangement having a wireless, connector-free coupling module (312) between the tool head (115) and the tool holder (206, 321) is provided for connecting the or each wear sensor (315) to an evaluation module (330). In this way, in the event of wear, a tool head (115) to be replaced may very easily be removed from the tool holder (206, 321) and a new tool head (115) may be connected to the tool holder (206, 321) very easily and in an electrically safe manner. A tunnel boring machine equipped with at least one cutting tool (106) of this type is thus operable in a very efficient manner.
