Abstract
A rockbolt assembly for securement within a borehole generally comprising a rockbolt, an anchor, a hollow tube assembly, a faceplate and a nut. The rockbolt has a threaded free end and a second end associated with the anchor. The hollow tube assembly has open first and second ends and an internally extending threaded portion configured to engage the rockbolt. The threaded portion is positioned between the ends with respective first and second tube areas defined on opposite sides thereof. At least one channel is defined in the tube assembly and extends from one tube area to the other such that a continuous passage traversing the threaded portion is defined between the ends of the tube assembly. The nut engages the tube assembly and the faceplate such that tightening of the nut about the tube assembly is translated through the rockbolt to cause engagement of the anchor.
