摘要： A shield-type support assembly for a mine working is composed of three substantially identical frames aligned side-by-side. Each frame has a floor sill structure which carries props capable of bracing a roof cap and the floor sill structure between the roof and floor of a mine working. A goaf shield is provided for each frame and these shields combine to screen off the goaf zone. The outer frames on the one hand and the central frame on the other are shiftable in alternation with the aid of shifting rams. One or more transverse arms extend across the forward regions of the frames and the or each arm is carried by the central frame floor sill structure. Guide devices are connected to the arm or arms and serve to guide the frames when shifted by the rams and the rams themselves transmit the shifting or reaction forces to the arm or arms.The coupling between the floor sill structures of the frames permits relative vertical mobility therebetween to cope with variations in the floor level of the working.

摘要： A roof support for a mine gallery which extends at a relatively large angle to the horizontal comprises an upper, a middle and a lower roof support unit arranged adjacent each other and having each a pair of elongated transversely spaced skids rigidly connected by bridges to each other and engaging the sole of the inclined mine gallery. An abutment beam likewise engaging the sole is arranged inclined to the elongation of the skids adjacent to the face of the gallery to be mined and connected to the skids of the middle roof support unit by a pair of flat sole plates rigid with the beam and tiltable about horizontal axes with respect to the skids, whereas the upper and the lower roof support unit are connected to the beam by flat elongated sole engaging end members connected to the beam pivotable about vertical pivot axes. In this way ample space is provided beneath the roof of the mine gallery between the beam and the roof support units to permit mining of coal seams of small height. The upper and the lower roof support units include elongated guide members in which advancing cylinder and piston units are located, and a pair of directing cylinder and piston units connect the elongated end members of the upper and lower roof supporting units with the adjacent sole plates of the middle unit.

摘要： A mineral mining installation is provided for use in a steeply-inclined longwall working. The installation comprises a ladder-shaped support frame, and a plurality of roof support units. The support frame extends along the entire length of the longwall working, and has a pair of generally parallel longitudinal beams interconnected by a plurality of transverse beams. The roof support units are positioned between the longitudinal beams, and are supported on the transverse beam. Each of the longitudinal beams comprises a plurality of beam sections pivotably connected together end-to-end. The support frame comprises a plurality of detachably connected sub-frames, each of which comprises a respective transverse beam and a respective beam section of each of the longitudinal beams.

摘要： Apparatus is disclosed for supporting the lowermost roof support unit of a series of roof support units positioned side-by-side in an inclined longwall working. The support apparatus comprises a beam mounted for pivotal movement in a plane parallel to the floor of the working. The beam can be held in any given angular position. A support plate is provided for engagement with the side of the lowermost roof support unit. The support plate is movable towards, and away from, the beam by means of hydraulic rams, which also constitute means for holding the support plate and the beam at any given spacing within a predetermined range of spacings.
