摘要： The invention relates to a rock anchor including an elongate, hydraulically inflatable anchor tube made of a ductile material and defining a closed leading end, a trailing end, and a tube cavity extending between the ends. The rock anchor of the invention includes an end cap on a trailing end of the tube, defining a feed aperture in communication with the tube cavity for pressure feeding a liquid substance into the tube cavity for inflating the tube. The end cap includes pressure indicator means configured for indicating when, as a result of pressure feeding of a liquid substance into the tube cavity, a predetermined installation pressure is reached in the tube cavity. The pressure indicator means typically includes a pressure indicator formation displaceable under pressure in the tube cavity, with such displacement being visible from the outside of the end cap.

摘要： An adjustable yield rock bolt that comprises an elongated tensile support member that interacts with at least one gouging member and a receiving member capable of receiving the elongated tensile support member and hold the gouging member segment there between, wherein the elongated tensile support member extends beyond the receiving member a length that corresponds to a predetermined amount of yield before ultimate failure. The bolt has adjustability by allowing for controlled yield by gouging of the elongated tensile support member for any length of displacement.

摘要： There is provided a tensioning device that includes an inflatable pressure vessel, a bellows arrangement, and a valve. The pressure vessel has two superimposed major wall components fabricated from sheet metal and further has an aperture which passes through the two superimposed major wall components. The aperture has an axial direction. The bellows arrangement is connected to and located between the two superimposed major wall components at and around the aperture. The valve is for filling the pressure vessel with liquid under pressure to cause the pressure vessel to be inflated in the axial direction of the aperture.

摘要： A tensionable mine roof cable bolt having a resin grouted upper portion and a mechanically anchored lower portion. The lower portion includes a shaft which is swaged to the cable and accepts a mechanical anchor. The cable bolt is rotated during installation in a mine roof bore hole to mix resin and simultaneously engage the mechanical anchor with the rock. A drivehead press fitted onto the lower end of the cable fails upon tensioning of the bolt to a predetermined load.

摘要： A tensioned truss system for supporting a face of a passage in a geological structure, such as a mine roof. Spaced anchors extending into the geological structure support corresponding truss transition brackets positioned adjacent the roof. The proximal end of each of the anchors is connected to the respective brackets so as to provide support and dual elongated truss members are attached to and span between the brackets for assisting in the support. The truss members are tensioned together through a driver mechanism carried by a drill head on a roof bolter machine. The driver mechanism includes a detachable drive adapter assembly having a pair of deep well or through sockets that engage rotary fasteners threaded onto one end of the truss members to apply the tension. Prior to tensioning, split wedge retainers are used to fix the other unthreaded end of the truss members. The brackets are interchangeable and include a frusto-conical bore for receiving the retainer, or which is spanned by a washer on the fastener. The drive adapter assembly is detachable from the drill head, and includes a flexible coupling and a worm gear to drive integral side by side pinion gears and deep well or through sockets for tensioning the fasteners. A color code is provided on one truss member to designate the required opposite hand thread.
