    Abstract: The present invention pertains to a mining support for supporting rock within a mine. The mining support is constructed of a cable and means for mixing resin in a resin cartridge as the cable is inserted into a bore hole drilled in the rock which the resin cartridge is disposed. In a preferred embodiment, the mixing means is comprised of a helical mixing strand which is fixedly attached to one end of the cable. The mining support can include a drive ferrule, swaged onto the cable, for driving the end of the cable into the bore hole. In a preferred embodiment, the drive ferrule is threaded and there is included a hex nut washer and contact plate for tensioning the cable after the resin has set. The present invention also pertains to a drive tool for driving a metal cable having drive ferrules disposed in proximity to either end of the cable into a bore hole containing a resin cartridge.

  • Patent number: 5526720
    Abstract: The present invention is a wrench device for installing a mine roof bolt. The device comprises a body portion having a socket end for holding and turning a nut of the mine roof bolt. There is also a retractable bolt stoppage mechanism engaged through the body portion. The bolt stoppage mechanism when raised prevents the bolt from threading onto the nut during resin mixing so as the nut is turned, the bolt is also turned. In a preferred embodiment, the body portion has a hollow central cavity which extends into the socket. The bolt stoppage mechanism can comprise a head portion and a rod portion slidably engaged within said central cavity. The bolt stoppage mechanism can also comprise a spring for biasing the stop member away from the socket end.

  • Patent number: 5387060
    Abstract: The present invention is a system for supporting rock within a mine having a bore hole. The system comprises a mining bolt having a round metal tube which has a completely hollow interior and all cross sectional dimensions less than that of the bore hole. The metal tube has a first end and a second end which are swaged closed to permanently close off the completely hollow interior so the bolt can crush and deform during movement of the rock when in place therein. The swaged second end has a square cross section to allow a tool to turn the mining bolt in the bore hole from the second end. The mining bolt has a metal washer flange fixedly attached to the metal tube adjacent to the swaged second end. The system also comprises a bearing plate disposed between the rock and the flange and a resin cartridge for bonding the mining bolt to the rock within the bore hole.

  • Patent number: 5114278
    Abstract: A mining bolt for holding rock comprised of an elongate shaft at least a portion of which has threads. The threads directly thread into the rock and are capable of supporting the bolt under tension in the rock. The mining bolt is also comprised of a flange system disposed about the shaft in proximity to one end thereof such that when the shaft is threaded into the rock, the flange system abuts under tension the rock's face. A method for holding rock in a mine comprising the steps of drilling a bore hole into the rock; and inserting the shaft of a mining bolt into the bore hole. The shaft has a flange system disposed about the shaft in proximity to the end thereof. The shaft has threads and is of a length longer than the length of the bore hole. There is also the step of screwing the shaft into the rock at the top of the bore hole such that the threads of the shaft penetrate into the rock and the flange abuts under tension the rock face.

  • Patent number: 4984938
    Abstract: The anchor bolt assembly is of the tensionable type used in mine roofs and the like in which the anchor bolt assembly is positioned in a bore hole of a rock formation. The bolt assembly includes an elongated bolt shaft with a head at one end and is threaded on the other end and has a mechanical expansion anchor on the threaded end. A bearing having a central opening is positioned on the bolt to engage a face of the rock formation. A two faced graphite coated washer is positioned on the bolt between the bolt head and the bearing plate. During installation, the washer acts as an anti-friction bearing between the bolt head and the plate to improve the torque to tension relationship.
