    摘要: The invention relates to a load support (1) comprising a container (2) manufactured from a flexible material, having at least one side wall (4), a top panel (3), a bottom panel (5), and a filler aperture (13). The side wall (4) has a predetermined height selected to be greater than the installation height of the support (1), operatively to allow for vertical expansion of the top of the container (2) into contact with the roof upon filling of the container (2) with a filler material.

    摘要: A high pressure bag for pre-stressing a support pack in an underground mine has a fluid impervious liner and three tubular envelopes. The liner is located in the first envelope with end portions of the first envelope and edge strips of the liner folded over underneath the first envelope. The first envelope with the liner therein are in the second envelope, with end portions of the second envelope folded over on top of the second envelope. The second envelope is located within the third envelope which has opposed edges stitched closed. The liner has a nozzle which extends through openings in the envelopes.

    摘要: The invention concerns a method and apparatus for providing yielding support for a hanging wall above a footwall in a mine working. A support assembly is installed between the hanging wall and the footwall, the assembly including a spacer (10), a pack (30) and a grout-inflatable bag (32). Grout is pumped into the bag (32) and is allowed to set to apply a vertical prestess force to the support assembly. The spacer (10) is substantially stiffer in compression than the pack (30), which is designed to yield under the compressive loading applied by the hanging wall. The use of a stiff spacer (10) serves to elevate the yielding pack to a suitble operative height without the allowable slenderness ratio for the pack to be exceeded.

    摘要: A yieldable confined core mine roof support including a container and a filler placed within the container. The container is yieldable and the filler is compressible. The combination of a filler within a container produces a mine roof support which is yieldable under a substantially axial load and which increases in load carrying ability as it yields, impeding any decrease in the distance between a mine roof and a mine floor, minimizing or preventing mine roof collapse and mine floor heave, buckling or punching.

    摘要: The prop preloading apparatus comprises a frame and means for supporting the frame on an end of an elongate prop in a manner permitting at least limited swivelling movement of the frame relative to the prop about at least one axis transverse to the axis of the prop. The apparatus also includes a flexible preload bag which is inflatable with a settable substance and which is dimensioned to be supported by the frame.

    摘要: A support between the floor (22) and the roof (24) of e.g. a mine stope, is made by using an inflatable container comprising an inner bag (10), received in an outer bag (12). An inlet valve (14) extends through both bags as does a relatively higher pressure relief outlet valve (16). In use, air is pumped into the container until it is fully inflated, following by a grout, the air escaping via the valve (16) until the inner bag (10) is filled.
