Overview

Expansion of existing tailings storage facility.

Detail

This project, located in Coolgardie, involved the key-in and construction of new tailings walls into existing pit walls, placement of general fill and low permeability material for the embankments and the installation of aggregate curtains and subsoil drainage for leak detections systems within the embankment walls.

Working around the backfilled pit RJV were required to maintain current pumping operations and ensure that the operations of the minesite were unaffected by the expansion works. Using 50T articulated dump trucks, 85T excavators, 14M grader and large 20T rollers RJV were able to complete the project successfully with no incidents.

RJV also undertook clay capping to the existing waste rock areas forming the perimeter for the existing TSF and the installation of various drainage structures, drain channels, rock protection and toe protection details for the expansion works.

The project also included the cartage of rock fill and low permeability material across Great Eastern Highway from neighbouring waste dump areas to make up the necessary material requirements for the expansion works.
