摘要： A mine roof bolt includes an elongated rod and a polymer coating layer. The elongated rod has a first end and a second end with a protruding portion extending radially outward from the elongated rod. The polymer coating layer covers at least a portion of the elongated rod between the first and second ends. The elongated rod is movable relative to the polymer coating layer in an axial direction. The elongated rod has a first position where the elongated rod has a predetermined axial position relative to the polymer coating layer and a second position where the elongated rod has a displaced axial position relative to the first position.

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 torque nut includes a threaded passageway and a groove. The groove has its opening facing the passageway. A breakaway insert having a major body portion is formed in the passageway, and a tab connected to the major body portion is formed in the groove, for example, by injection molding. The tab connected to the major body portion prevents rotation of the insert in the passageway. In one use, a resin component, a catalyst component and a first end of a rock-bolt are positioned in a bore hole. The torque nut is threaded onto the opposite end of the rock-bolt. Rotation of the torque nut rotates the rock-bolt, mixing the components. After the components set, increased torque is applied to the torque nut to fracture the insert and move the nut up the threaded end of the rock-bolt against roof stabilizing components.
