ABSTRACT:
An expansion anchor including an expansible shell and tapered nut for insertion into a drill hole in a rock formation and adapted for outward expansion of the shell into gripping engagement with the drill hole wall to support a rock bolt and bearing plate engaging the rock formation surface around the hole. The invention resides in a novel arrangement of dimensional and structural relationships of the expansion shell and tapered nut which allow the same anchor to be used in drill holes over a range of diameters approximately three times that of conventional prior art anchors of the same general type.
