A driving or mining machine includes a pivotable cantilever arm that is hinged so as to be pivotable in the height direction to a pivoting mechanism capable of being pivoted about a substantially vertical axis and on its free end carries rotationally mounted excavation tools, in particular cutter heads. It further includes a traveling mechanism and a frame carrying the traveling mechanism, on which frame a haulage device and a suction device as well as anchor boring and setting devices are arranged. The frame carrying the traveling mechanism on its side facing away from the cantilever arm behind the pivoting mechanism is designed as a lowered platform. The anchor boring and setting device is arranged substantially in the longitudinal center of the frame above the platform and pivotally mounted on a rollover whose pivot axis crosses the vertical axis of the pivoting mechanism. The pivot angle of the anchor boring and setting device is larger than 180° and extends to below the horizontal plane containing the pivot axis of the rollover.
In a driving or mining machine of the type including a pivoting mechanism capable of being pivoted about a substantially vertical axis, a pivotable cantilever arm hinged to said pivoting mechanism so as to be pivotable in the height direction and having a free cantilever arm end, excavation tools rotationally mounted on the free end of the cantilever arm, a traveling mechanism, a frame supporting said traveling mechanism, a means for suction, and a means for anchor boring and setting arranged on said frame, the improvement wherein:
