Design and Construction of a Plastic Concrete Cutoff Wall for the Island Copper Mine

Source

A plastic concrete slurry wall was constructed at the Island Copper Mine on Vancouver Island to prevent excessive seepage from the ocean into a large copper mine open pit during a south wall push-back which would lead to pit slope stability problems and flooding. An unusually low strength plastic concrete was chosen as a backfill to sustain relatively large deformations without cracking and to resist erosion if a crack should develop. Very difficult construction problems were successfully surmounted including excavation through a loose, pervious mine rock waste dump and embedding the toe of the wall into a very hard glacial till. Pit slope excavation has been completed through the cutoff soils without problem.
