A boring rig ( 14 ) for underground boring for excavating purposes and including a substructure ( 21, 22 ), a propulsion device, a stabilizing device ( 31, 32, 35, 36, 37, 38, 39, 42 ), and a boring unit ( 20 ) having a cutter head ( 29 ) and a rotation and forcing device ( 26 ), in which the rig has a first direction of general travel and two sideways directions, and in which the boring unit ( 20 ) is pivotally attached to the substructure for pivotal movement of the boring unit into an operating direction. The stabilizing device includes horizontal ( 31, 32 ) and vertical ( 35, 36, 37, 38, 39 ) stabilizing elements that are attached to the substructure ( 21, 22 ) in order, in active positions, to be pressed against an adjacent rock face so as to transmit forces from the boring unit ( 20 ), that are occurring during boring, to the rock face. |
