    • A shield-type support frame for serving as a face support in underground mining operations having a bottom structure, a one-piece roof cap, at least one hydraulic plunger connecting the bottom structure and the roof cap and two shield elements arranged side by side, which can be adjusted in height separately and which are each pivotally connected to the bottom structure and the roof cap. Joint connections between each shield element and the roof cap permit tilting of the roof cap relative to the shield elements about axes extending in the forward direction. In such a shield-type support frame, the roof cap is guided better in the forward direction and tilting of the roof cap about a vertical axis is prevented by the joint connections between the shield elements and the roof cap each having a hinge connection with two hinge pins of which the one extends in the face length direction and the other in the forward direction, where the roof cap is supported by the hinge pins extending in the forward direction and the shield elements by the hinge pins extending in the face length direction.

    • In a roof-shield support system employed in mines, at least two levelling rams each acting between a shield frame unit and an associated gap-seal plate, the latter being arranged so as to be slidable relative to the associated shield frame unit. Each levelling ram comprises a cylinder, piston and piston rod, is arranged so that the piston rod has a longitudinal bore which is open at the piston end of the piston rod, and an elongated rod which is sealed relative to the piston rod being disposed within said bore. The bore is in use in communication with a hydraulic fluid system of the ram and after levelling has occurred by actuation of the ram the pressurized hydraulic fluid admitted into the bore applies a force to the associated gap-seal plate so as to ensure its continuing tight engagement with the adjacent shield frame unit.

    • An advancing excavation roof support has a base and a shield assembly above the base. The base has two base portions which are spaced from one another at its end which faces toward the face of the excavation, and a lifting member is mounted between the two base portions for pivoting about an axis. A hydraulic cylinder-and-piston unit extends between the base and the lifting member and pivots the latter about its pivoting axis between a retracted position in which the lifting member is out of contact with the excavation floor, and an extended position in which an engaging portion of the lifting member engages the excavation floor and is downwardly spaced from the base so that the one end of the base which faces the excavation face is elevated and digging thereof into the excavation floor is prevented. The lifting member may be either of box-shaped configuration with an open top, and in that case a transverse beam rigid with the base portions carries a downwardly extending cylinder-and-piston assembly engaging the lifting member intermediate the axis and the engaging portion thereof, or a single-acting lever mounted on a pivot in an upper region of the base, and in that event cylinder-and-piston assembly exerts a force on the lever in direction toward the excavation face.
