Definitions

  • Bolting In underground mining and strata control, bolting is generally recognised as the primary support system. Bolting usually involves grouting of a rock bolt within a bolt hole formed in the strata of an underground mine. The bolt is commonly tensioned using a 2-speed resin capsule so that the strata surrounding the bolthole is held in compression. This technique has been extended to cables or tendons where generally a barrel and wedge fitting is attached to the cable and is tensioned using hydraulically actuated equipment.
  • the capsule includes an outer membrane containing the grout or resin and the step of laterally displacing the capsule involves advancing the cable or tendon within the cavity pushing the membrane aside with the oblique surface.
  • the elongate cavity is in a pre-grouting step partly loaded or filled with capsules containing grout or resin.
  • the capsules are broken with the advancing cable 12 or tendon to release the resin or grout which sets to secure a distal end of the cable 12 or tendon within the cavity.
  • the cable 12 or tendon is tensioned by rotating the nut 20 around the thread portion 18 which drives a strata or volcano plate 34 against the strata to compress it about the cavity.
  • An intermediate domed washer and bearing assembly 36 is located between the nut 20 and the volcano plate 34. Operation and construction of the tensioning device 10 is otherwise described in some detail in the applicant's international patent application no.
  • the tensioning device of this embodiment is preferably fabricated from steel, any suitable material such as plastic or alloy would suffice.
  • the tensioning device may also provide for a different porting or grout/resin entry point to that described.
  • the cutting or piercing to is not limiting to the shape described but may extend to other asymmetric shapes and configurations.
  • the steel strands of the braided cable or tendon may be fabricated of other materials such as plastics.
  • the present embodiments are, therefore, to be considered in all respects as illustrated and not restrictive.
