    摘要: A mixing head attachment is provided for use in mixing grouts and/or resins (hereinafter for brevity collectively referred to as resin) used in mine roof support systems in the securement of an anchor bolt in a bore hole. A threaded fastener is provided to tension the anchor bolt, and a resin composition is used to secure at least part of the anchor rod in the bore hole. The mixing head attachment is provided with a rigid or semi-rigid body which extends axially along a body axis, and has sufficient structural integrity to effect mixing of unset resin as the mixing head is rotated about its axis. The mixing head attachment includes one or more mixing blades or projections which define a mixing surface or face. A recess is formed in a proximal-most end of the body, sized and shaped for mated engagement with a distal end of the anchor bolt, allowing mixing head attachment to be in generally co-axial arrangement to the anchor bolt with a sufficient minimum contact force selected so that while the resin remains unset, the rotation or spinning of the anchor rod in the bore hole effects rotation of the mixing attachment about its axis therewith.

    摘要: A mine roof support system includes an elongated anchor rod or tendon having a rigid non-deformable distalmost anchoring end portion, and one or more axially deformable portions which are configured to deform in the event load forces exceed a threshold force approximating the forces during a rock burst or rock dilation event. The rigid anchoring portion is provided with primary anchor members such as ribs, grooves, studs and the like. The primary anchor members are configured to reduce bar plasticity, and fixedly secure and retain the rigid portion in place in a drill hole. In the event rock forces exceed the threshold force, the plastically deformable portions elongate with the dilating rock to accommodate and absorb the rock forces.

    摘要: A mine roof support assembly for anchoring in a bore hole by means of a resin, cementitious grout which includes an elongated reinforcing tendon which extends from a proximal end portion to a distal end portion. A slip sheath formed from a heat shrunk plastic, is secured by heat shrinkage radially about the tendon. The sheath is mechanically coupled to the tendon so as to allow the desired axial sliding of the tendon relative to the sheath on the application of predetermined forces which sufficient to effect any desired yielding movement of the tendon in the bore hole. An anti-bonding agent or coating and/or anticorrosive may be interposed between the sheath and the tendon, whereby the sheath substantially encapsulates and limits the admixing of the interposed anti-bonding agent/anti-corrosive coating with the resin.
