摘要： An apparatus for cutting excavations having a substantially planar face comprises a cutting tool which is rotatably mounted on a jib. The jib is mounted on a mobile machine for a pivotal movement in a plane which is transverse to the heading direction and is divided into two jib sections which are pivotally movable relative to each other about an axis which is substantially parallel to the pivotal axis of the jib. The cutting tool is rotatably mounted close to or at the free end of that jib section which is most remote from the pivotal axis of the jib.

摘要： A drift advancing or a partial-cut mining machine (1) comprises a cutting arm (11) being swivellable in a height direction around an axis (10). The front end of the cutting arm (11) is equipped with guides (26) transversely extending relative to the longitudinal axis (38) of the cutting arm (11) and having shiftably supported thereon a carrier (27) for the cutting heads (28, 29). The cutting heads (28, 29) are rotatably supported on the carrier (27) for rotation around vertical axes (46). The distance (a) between the axes of rotation (46) is, as measured in a transverse direction relative to the longitudinal axis (38) of the cutting arm, at most equal to half the width (b) of the drift face.

摘要： A cutting machine (1) includes on its base frame (3) a carrier construction (19) for wall elements (21) and appliances (20) for drilling anchor bores and applying anchors the carrier construction being shiftable in longitudinal direction of the machine. The wall elements (21) are adjoining the drift roof (22) and, respectively, a cutting arm (11) via elastic sealing elements (23). The cutting arm (11) and the charging means (15) are pivotally linked to a shiftable frame (42). The cutting heads (28, 29) can be shifted along guides (31) in transverse relation to the longitudinal axis of the drift, the cutting heads (28, 29) being arranged between drift face (33) and wall elements (21).
