Abstract (en)
[origin: US6431653B1] The tunnel rock drill (100) for driving a tunnel bore optionally in open or shielded mode comprises a shield tail (33), which is connected to the drill head (10) and which covers optionally the bore wall over a defined length; a bracing device (20), which can be optionally fixed in the tunnel bore; at least one optionally activaatable advancement device (25), which, on the one hand, rests on the bracing device (20) and , on the other hand, acts on the drill head (10); and an optionally activatable force generator (35), which has a variable length and which, on the one hand, rests on a tubbing support (32) and, on the other hand, acts on the drill head (10). To introduce the advancement forces into the drill head in open mode, there is an inner kelly (16), which can be moved in the direction of boring in relation to the bracing device (20) and to which the advancement generator (25) is hinged and whose breast-sided end bears the drill head (10).
