    Abstract: New prop assemblies, suitable for a range of uses, including in mines and construction, have a pole subassembly. The pole subassembly includes:



    a first prop part and a second prop part, the first prop part being axially movable with respect to the second prop part;
    a first extending means adapted to enable the first prop part to be moved in a first adjustment with respect to the second prop part; and either or both:
    a second extending means adapted to enable the first prop part to be moved in a second adjustment with respect to the second prop part; or
    a third extending means, adapted to adjust a length of the prop assembly.

    Abstract: A mine prop is comprised of an elongate tube having a slenderness ratio that would generally allow buckling or kneeling of the elongate tube when exposed to a sufficient axial force. A plurality of elongate support members having a length less than the elongate tube are attached to the tube to prevent buckling or kneeling of the elongate tube along the portion of the tube to which the elongate support members are attached. The portions of the tube that are unsupported by the elongate support members define one or more yieldable zones proximate at least one end of the tube. A compressible filler material is disposed within at least portion of the tube to support yielding in the yieldable zone.

    Abstract translation: 矿井支柱由细长管组成，细长管通常在暴露于足够的轴向力时允许细长管的屈曲或跪下。 具有小于细长管的长度的多个细长支撑构件附接到管，以防止细长管沿着细长支撑构件附接到的管的部分弯曲或跪下。 管未被细长支撑构件支撑的部分限定了在管的至少一端附近的一个或多个可屈服区。 可压缩填料材料设置在管的至少部分内以支撑在可屈服区域中的屈服。

    Abstract: The invention concerns a prop headboard (10) which is used in conjunction with an elongate mine prop. The headboard supports a preload bag (50) inflatable with a settable grout. The headboard is composed of a headboard member (12) and a pot (34). The headboard member includes a pressed steel sheet (14) having relatively higher end regions (16) and a relatively lower central region (22). The central region is formed with an opening (24). The headboard member also has bag retaining formations (30) which receive opposite ends of a preload bag located on the headboard member. The pot is engaged in the opening in the central region and receives the upper end of an elongate prop, thus supporting the headboard member on the prop with the headboard member extending transversely to the prop.

    Abstract: 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.

    Abstract: A mine prop includes a first pipe having a first end and a second end, a second pipe having a first end and a second end, and a yield member secured to the second pipe. The second pipe is slidably received in the first pipe. The yield member is configured to yield before the first and second pipes when the mine prop is placed under a predetermined load.
