  • Patent number: 4263005
    Abstract: The invention refers to a device with which provisional consolidating frames adapted to be brought to a smaller size can be transported to the drift face and can be put in place. According to the invention this device is arranged on the cutting machine itself so that the narrow space remaining between the contour of the cutting machine and the cross section of the drift is sufficient for transporting in forward direction and putting in place the provisional consolidating frames without the necessity to retract the face advancement machine from the drift face. Thus, face advancement machines can be used which occupy the major part of the inside width of the drift, noting that the face advancing machine is maintained in its working position. The invention further describes a doorjamb frame for the provisional drift consolidation and which is particularly suitable for the device proposed.
