A resin injection apparatus (19) for use in connection with a drilling apparatus (10) for installing ground anchors. The resin injection apparatus(19) comprises a fluid injector (20), adapted to be connected in fluid communication with a hollow drill shaft (21) of a drill rig (10). The fluid injector (20) can be used to inject one or more resin fluids into the drill shaft (21) wherein, in use, when a hole has been drilled in a rock stratum, resin can be injected into the hole via the drill shaft prior to inserting a ground anchor. |
