摘要： A rock bolt is for use in stabilizing a rock face. The rock bolt comprises a body having a plurality of elongate lobes spaced apart by substantially resilient channel means. The rock bolt is further configured to receive expansion means for urging the lobes outwardly to thereby expand the rock bolt for improving a communication with a bore hole in the rock face. Following expansion the expansion means may be removable, the expansion means can comprise any suitably sized hollow or solid bar expansion member. The configuration of the present invention also enables, subsequent to an initial expansion, the resilient channel means to provide a gripping force on any suitably sized member inserted into the internal space. This feature of the rock bolt allows for a mesh plate having an elongate portion to be securely and removably fitted to the rock bolt after the rock bolt has been expanded.

摘要： A yielding rock bolt having a solid metal shaft with a relatively wide portion and a relatively narrow portion and an anchor member mounted about the shaft. The anchor member has longitudinal bore which is of lesser dimension than the relatively wide portion. The anchor member is mounted about the relatively narrow portion adjacent the wide portion. In use the shaft is extruded through the anchor member to cause the rock to yield as a rock face moves.
摘要翻译：一种产生的岩石螺栓，其具有相对宽的部分和相对窄的部分的固体金属轴和围绕轴安装的锚固构件。锚定构件具有比相对较宽部分更小尺寸的纵向孔。锚固构件围绕邻近宽部分的相对较窄的部分安装。在使用中，轴通过锚固构件挤出，以使岩石随着岩石的移动而屈服。

摘要： A cable bolt is provided that is suited to stabilize rock surfaces, particularly to withstand loads placed on the cable bolt when tensioned to stabilize rock surfaces of coal mines. The cable bolt comprises a tendon composed of a plurality of strands, the tendon having a plurality of pre-formed bulbous portions. The bulbous portions house rigid elements, such as a ball bearing, which are inserted after the bulbous portions are formed. When the cable bolt is tensioned or stressed, the load placed on the bulbous portion will be resisted by the rigid element housed within the bulbous portion, thereby preventing the bulbous portion from collapsing.
摘要翻译：提供了一种适用于稳定岩石表面的电缆螺栓，特别是当张紧以承受放置在电缆螺栓上的载荷以稳定煤矿的岩石表面时。电缆螺栓包括由多根股线构成的钢筋，该钢筋具有多个预先形成的球形部分。球形部分容纳在形成球根部之后插入的刚性元件，例如球轴承。当电缆螺栓张紧或应力时，放置在球根部分上的负载将被容纳在球形部分内的刚性元件抵抗，从而防止球茎部分塌陷。
