Description Of Project

The Olympic Dam mine located 560km north of Adelaide is a world class mining and mineral processing operation exploiting a multi-mineral ore body containing uranium oxide, copper, gold, and silver. The facility is owned and operated by the BHP group.

The current Olympic Dam underground mine consists of two interlinked mining areas: the northern mine area, and the emerging southern mine area. BHP have developed a mine plan to access the ore in the southern mine area, which offers the Olympic Dam mine access to more and higher-grade ores. As part of the development of this area of the mine, materials handling systems were required to support mine production. The provision of suitable and efficient underground rock transport and surface delivery systems were critical to the success of the Southern Mine Area.

SYSTRA Bamser Involvement

As part of BHP’s strategy to develop the southern mine area (SMA) at Olympic Dam, Downer Engineering were engaged by BHP to undertake an Early Contractor Involvement (ECI) study to provide a safe and innovative construction methodology and sequence for the installation of the Materials Handling System at SMA.

Downer engaged SYSTRA Bamser to provide independent underground construction advice and support services to assist in the development of the ECI study submission.

Specifically, SYSTRA Bamser provided support in the following areas:

  • Review methods and provide input into the construction methodology and staging for underground construction sections of the project;
  • Rail track structure proposal and recommendation;
  • Coordinate preparation of and collate the EIC study report document;
  • Provide cost estimation support and procurement options advice; and
  • Provide advice on construction logistics.
