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).
