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 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.
摘要翻译：扭矩螺母包括螺纹通道和凹槽。槽的开口面向通道。在通路中形成有具有主体部分的分离插入件，并且例如通过注射成型在凹槽中形成连接到主体部分的突片。连接到主体部分的突片防止插入件在通道中旋转。在一种用途中，将一种树脂组分，催化剂组分和岩石螺栓的第一端定位在钻孔中。扭矩螺母拧到岩栓的另一端。扭矩螺母的旋转旋转岩石螺栓，混合组件。在组件设置之后，向扭矩螺母施加增加的扭矩以破坏插入件，并将螺母向上移动到螺栓的螺纹端部以抵抗顶部稳定部件。

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.
摘要翻译：提供混合头附件，用于在井壁支撑系统中使用的用于固定钻孔中的锚定螺栓的砂浆和/或树脂（以下简称为统称为树脂）。提供螺纹紧固件以拉紧锚定螺栓，并且使用树脂组合物将至少一部分锚杆固定在钻孔中。混合头附件设置有刚体或半刚体，其沿主体轴线轴向延伸，并且具有足够的结构完整性，以在混合头绕其轴线旋转时实现未固定树脂的混合。混合头附件包括限定混合表面或面的一个或多个混合叶片或突起。在主体的最近端部形成凹部，其尺寸和形状用于与锚定螺栓的远端配合接合，允许将头部附件与大体上同轴的布置与锚定螺栓具有足够的最小接触选择的力，使得当树脂保持未设定时，锚杆在钻孔中的旋转或旋转使混合附件围绕其轴线旋转。
