摘要： A tensionable mine roof cable bolt having a resin grouted upper portion and a mechanically anchored lower portion. The lower portion includes a shaft which is swaged to the cable and accepts a mechanical anchor. The cable bolt is rotated during installation in a mine roof to mix resin and simultaneously engage the mechanical anchor with the rock. A drivehead attached to the lower end of the cable fails upon tensioning of the bolt to a predetermined load.

摘要： A tensionable combination mine roof bolt is disclosed for use in resin grouted applications. The mine roof bolt includes a lower rod member having a rotatable bolt head at a first end thereof supporting a bearing plate and a threaded second end spaced from the first end. A coupling threadingly receives the lower rod member therein. A shearable stop device, such as a shear pin, is positioned within the coupling and adapted to stop the threaded lower rod member at a first position for rotation of the cable mine roof bolt during installation. After an upper portion of the cable mine roof bolt is secured, the shearable stop mechanism is subsequently sheared by the lower rod member to allow for tensioning of the cable mine roof bolt. A flexible multi-strand cable is coupled to the coupling device and forms the attachment point for the cable mine roof bolt.

摘要： An elongated rod fabricated of polymeric material for use in reinforcing an underground passage includes an integral structure of a shaft portion, washer element and torque receiving end portion. The shaft portion is fabricated of a preselected polymeric material as required to meet the strength requirements of the rod in reinforcing the rock formation surrounding the passage. For use in reinforcing the side walls of a passage, the rod is fabricated of plastic material recycled, for example, from plastic beverage containers. The integral construction eliminates the need to thread the end of the rod to receive a nut. The washer element seats against a bearing block compressed against the side wall. When used with a resin system, the rod is anchored in the bore hole to maintain the bearing block compressed against the side wall to support the surrounding rock strata.

摘要： A flexible multi-strand steel cable of a preselected length is inserted in a bore hole drilled in a rock formation above an underground excavation. The cable includes an anchor end portion positioned in the bore hole for frictionally engaging the cable to the wall of the bore hole. The anchor end portion may also be chemically bonded to the surrounding rock formation. The cable extends out of the bore hole and includes a drive end portion that retains a bearing plate opposite the opening into the bore hole. The drive end portion includes a pair of diametrically positioned jaw members on the cable. The jaw members form a frustoconical outer surface positioned within a tapered bore of a collar. The collar advances on the jaw members to compress them into nonrotational gripping engagement with the steel cable. End portions of the jaw members extend out of the collar on the cable. A torque transmitting device engages the ends of the jaw members removed from contact with the collar to transmit upward thrust and rotation through the jaw members to the cable and place the anchored cable in tension to reinforce the overlying strata of the rock formation.
