Challenger Gold Mine Geotechnical Review

Central South Australia

The Challenger Gold Mine is located in the remote centre of South Australia, 700 km north-west of Adelaide. Open-cut mining commenced in 2002 and was followed by the development of an underground mine in 2004. The mine had reached a depth beyond 1,000 m when pitt&sherry was engaged to review ground support and reinforcement practices at the operation.

A comprehensive review of the geomechanics of the mine was undertaken with the aim of providing a sound engineering justification for the ground support and reinforcement standard designs. This resulted in a reduction in consumable usage of up to 30 per cent across the operation.

pitt&sherry then wrote the new standards into the Ground Control Management Plan and assisted Challenger Gold Mine staff in benchmarking that document and upgrading it to current industry standards. The work undertaken by pitt&sherry with the Challenger Gold Mine staff was ultimately published at the International Seminar on Design Methods in Underground Mining in 2015*.
