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.
摘要翻译：一种用于通过树脂锚固在钻孔中的矿山屋顶支撑组件，其包括从近端部分延伸到远端部分的细长的加强筋。由热收缩塑料形成的滑动鞘通过围绕腱径向的热收缩而固定。护套机械地联接到腱上，以便在施加足以实现榫孔中的腱的任何期望屈服运动的预定力的作用下允许腱相对于护套的期望的轴向滑动。可以在护套和腱之间插入抗粘合剂或涂层和/或防腐蚀剂，由此护套基本上封装并限制了插入的抗粘连剂/防腐蚀涂料与树脂的混合。
