Definitions
- the invention relates to a shield driving device with a a mining space perpendicular to the tunnel axis delimiting wall, with a rear the baffle located on the baffle, the a pressure wall is closed perpendicular to the tunnel axis, and with an annular space discharge device, those in the annulus behind one in the diving wall brought in, with a baffle closure device closable baffle opening is arranged so that from material entering the annulus into the annular space can be removed is.
- the known shield jacking device has one The baffle that delimits the installation space, together with a Pressure wall arranged on the tunnel room side and a shield jacket encloses an annulus.
- an annulus discharge device is provided in the annulus in the area a lockable with a baffle closure device, baffle opening in the lower area of the baffle an annulus discharge device is provided with which a liquid-assisted mining operation from the mining room in material entering the annulus is removable.
- DE 37 41 460 C2 is a shield driving device known, via a screw conveyor flanged to a baffle and also flanged to the diving wall hydraulic conveyor.
- This for Mining operation with supports for the working face using earth pressure, compressed air or support fluid set up shield jacking device has a screw opening closure device in order to the screw conveyor device in a liquid-assisted mining operation to empty and to apply compressed air, so that a screw conveyor tube as a pressure chamber for Compensation of pressure fluctuations in the support fluid is used.
- This device is a mining operation with supports Face can be carried out using earth pressure or supporting fluid, however, it has the disadvantage that maintenance work in particular at the entrance to the hydraulic conveyor only with a compressed air-supported working face under accordingly difficult and dangerous conditions is possible.
