Abstract: The present invention is directed to an anchor assembly for installing a threaded mine-roof bolt under tension in a bore hole formed in underground passageways, mines, and the like. The anchor assembly includes a two compartment resin cartridge and a mechanical expansion unit. A support collar is threaded on the bolt to restrict axial movement of the mechanical expansion unit. The mechanical expansion unit includes a camming plug and an expansion shell. The expansion shell has a plurality of fingers extending upwardly from an annular collar. Spaces or slots are formed between adjacent fingers. Each of the plurality of fingers include a vertically extending rib for forming channels between the external surfaces of the fingers and the side walls of the bore hole to permit the free flow of resin. The side surfaces of the fingers adjacent the uppermost portion thereof are tapered so that substantially V-shaped notches are formed between adjacent fingers. Vertically extending recesses are formed in the camming plug. At least one of the vertically extending recesses of the camming plug is aligned with at least one V-shaped notch formed in the mechanical expansion shell. This arrangement of aligning at least one recess and one V-shaped notch further facilitates the free flow of resin about the anchor assembly components.

Abstract: An assembly and methods of installation thereof for supporting and stabilizing a rock structure adjacent a mine tunnel or other underground passageway. The assembly includes an elongated bolt, threaded from both ends for at least a portion of its length. A conventional, mechanical expansion anchor is threaded on one end of the bolt, within a drill hole in the rock structure, and a bearing plate, washer, jam nut and tensioning nut are carried on the other end, outside the drill hole. The tensioning nut is threaded into firm engagement with the jam nut to prevent further threaded advance of the tensioning nut a substantial distance from the termination of the threads. A torque applied to the tensioning nut thus rotates the bolt and expands the anchor shell into gripping engagement with the bore hole wall; torque producing an axial load on the jam nut in excess of its strength causes it to fracture or strip from threaded engagement with the bolt, permitting travel of the tensioning nut. The jam nut is received in a recess in the lower surface of the washer, which is preferably spherical on its upper surface.

Abstract: A resin reinforced expansion anchor system for a mine roof support bolt or the like utilizes a specially configured, thin-walled expansion shell together with a thin-walled, dual-taper plug for expanding the shell. The shell and the plug cooperate to implement a particularly desirable type of mechanical expansion anchoring action while simultaneously providing a symmetrical array of resin flow passages at circumferentially spaced locations about the anchor assembly to permit proper distribution and flow of a quick setting resin mix. The system of the invention enables a relatively large diameter rock bolt or threaded bar to be securely anchored in a blind drilled hole that is of relatively small diameter, with the anchoring action of a mechanical expansion anchor assembly being desirably augumented by the anchoring action of a concurrently established resin bond. The system of the present invention has particular utility in providing a means for effecting combined mechanical expansion anchoring and resin bond anchoring of a relatively large diameter threaded member such as a 7/8" rock bolt that is installed in a relatively small diameter hole such as a 13/8" blind drilled hole that is formed in a mine roof or the like.

Abstract: A reinforcing and support system and method of installation thereof including both a mechanical expansion anchor on the distal end of an elongated bolt and a resin grouting mix installed in a blind drill hole in a mine roof, or the like. A pair of elongated leg members, fixed with respect to the shell, extend into the annular space surrounding the bolt below the shell for a distance about as great as the axial length of the shell. Upon advance of the bolt, carrying the expansion anchor and leg members, into the drill hole to break a cartridge containing the initially flowable components of the grouting material, the bolt is rotated to effect expansion of the anchor and tensioning of the bolt. Mixing of the components in the annular space surrounding the bolt below the anchor as the bolt is rotated is enhanced by hydraulic turbulence produced by flow of the components about the leg members. A support nut may be installed on the bolt below the anchor, and the leg members may be fixedly attached to one another near their terminal ends.

Abstract: A mine roof expansion anchor having a conventional tapered camming plug and radially expansible shell having associated therewith an element which resiliently engages the wall of a bore hole as a roof bolt carrying the anchor is inserted in the hole. The resilient element may be incorporated in the structure of a bail having bore wall engagement portions position in a plane closer to the lower end of the expansion shell than the lowest position of the tapered plug after full expansion. The engagement portions may comprise outwardly and downwardly extending portions of the bail legs, either at the terminal ends or pierced from the bail material slightly above the ends. In another embodiment, the engagement portions extend from a support nut positioned on the bolt below the lower end of the shell.

Abstract: A nut for use with an elongated rod having one end anchored by a hardened resin grouting mix in a drill hole in a mine roof or other such rock formation. The nut has a body portion with a threaded bore through which the rod is advanced and a dome-shaped wall surrounding one end of the bore in radially outwardly spaced relation and an annular lip defining an opening in coaxial, axially spaced relation to the one end of the bore. A metal disc, either solid or with a central opening of smaller diameter than the bore, is positioned in covering relation to the bore and surrounded by the dome-shaped wall. As the rod is advanced through the nut, the disc is moved into contact about its entire periphery with the inside of the dome-shaped wall and rotation of the nut is transmitted to the rod to mix the resin components within the drill hole. After the mix hardens, excess torque applied to the nut deforms the nut toward the dome shape of the wall and eventually fractures the annular lip, thereby expanding the opening and expelling the disc. The torque required to fracture the nut is considerably higher when the disc is incorporated in the nut structure, thereby ensuring complete mixing of the resin components prior to fracture.

Abstract: A threaded fastener and method of fabrication thereof wherein the fastener or nut includes a first portion having external, wrench-engaging surfaces and a central, through bore, internally threaded for at least a portion of its length from a base surface. A wall portion extends integrally from the end of the first portion opposite the base surface, concentrically surrounding and spaced radially outwardly from the end of the bore. The first and wall portions are formed as a metal casting with the wall portion in two segments separated by longitudinally extending, V-shaped notches. The free edges of the wall segments, which initially lie in a plane normal to the axis of the bore, are deformed by a die, moving radially inward so that the wall segments are in a domed configuration with the free edges defining a substantially oval opening having a major axis with a length about equal to the diameter of the bore and a minor axis about 4/5 that of the major axis. A method of supporting a mine roof using such a threaded fastener with a bearing plate, resin cartridge and elongated rod having threads mating with the internal threads of the bore is also disclosed.
