Results of the radius factor stability assessment method for design and pillar extraction at the Conqueror Mine, St Ives Gold Mine

Author: Andrews P, Barsanti B

The St Ives Gold mine is located on Lake Lefroy, approximately 60 km south of Kalgoorlie. The site at present comprises three underground operations and four active open pits. It produces approximately 484 kg of gold annually.

Defining the role of elastic modelling in underground mine design

Author: Barsanti B, Basson F

In recent decades, geotechnical engineers have been forced to consider and develop a rigorous approach to problem solving through conscious (explicit) model building. Conscious model building is a process of developing a model with a well-defined purpose recognised by the model builder.

Simulate waste rock flow during co-disposal for dilution control

Author: Basson F, Dalton N, Barsanti B, Flemmer A

The Callie underground gold mine (CUG) is located 531 km north-west of Alice Springs in the Northern Territory. The underground mine has been in production since 1998 with a current mine depth of 1,400 m below surface.

Harvesting tailings from an active tailings storage facility: success and challenges – Frog’s Leg mine, Evolution Mining

Author: Gopalakrishnan V, Nester T, Mgumbwa J, Holtzhausen W

Frog’s Leg mine is part of the Mungari Gold Operations (MGO) owned by Evolution mining and is located 20 km west of Kalgoorlie in the Kundana mining region. The mine uses undercut long-hole stoping with cemented paste fill (CPF) as backfill for the continuous end on retreat ore extraction.

Managing the onset of accelerated deformation in capital development at Agnew Gold Mine

Author: Moulding C, Stephenson R, Barsanti B, Francis D

The Kim Lode at Waroonga Underground (Agnew Gold Mine) extracts ore using a longhole open stoping method. The orezone dips west at approximately 65° and predominantly lies between a sandstone hanging wall contact and an ultra-mafic footwall.

Stability of Pillars and Tabular Excavations under Shear Loading Conditions–Implications for Mine Planning and Design

Author: Meyer S, Doolan J, Chester C, Basson G

Rockbursts are well known hazards in deep hard rock mines and tunnels, posing serious threats to production and personnel safety. To date, the reasons for the occurrence of some rockburst events cannot be explained with conventional rockburst genesis mechanisms.
