    摘要： A mobile mine roof support in which a rear shield is pivotally and shiftably attached at one end to the rear end of a sole plate and extends upwardly and forwardly curved therefrom. A mine roof supporting cap is pivotally attached intermediate its ends to the other end of the rear shield and an extensible and contractable prop is pivotally connected at opposite ends to the sole plate and the rear shield, respectively, to thereby press the cap against the roof of a mine gallery, whereby depending on the extension and inclination of the prop, the vertical distance between the sole plate and cap as well as the horizontal distance between the front end of the cap and the front end of the sole plate may be changed. To prevent tipping over of the mine roof support under the pressure of the mine roof exerted on the cap, when the front end of the latter extends too far beyond the front end of the sole plate, extension means are provided which are releasably but rigidly attachable to the front end of the sole plate to rest, as the latter, on the floor of the mine gallery.

    摘要： The roof of an underground excavation is supported by a lining, and a conveyor extending along the mine face is reinforced at least in a section facing away from the mine face and supporting at least one cantilever beam and a hydraulic advancement assembly. A floor base of the lining is provided with recesses for guidingly accommodating the cantilever beam in the floor base, so as to permit relative movement of the conveyor and the lining in the direction perpendicular to the mine face, the lining and the conveyor alternately serving as retaining means for each other during the step-wise advancement of the combination.

    摘要： A lining for underground excavations comprises a floor base, a shield, a roof cap for supporting the mine roof, a pit prop for engaging the floor base and the shield and pushing the roof cap into abutment with the mine roof, and a support assembly for displacing a lower end of the shield along an arcuate path and fixing it in a plurality of positions along this path.
