Monitoring the Performance of Underground Excavations Workshop

2 November 2020


Modern underground mine infrastructures are generally built to minimise the risk of accidents associated with rockfalls or production delays due to excessive tunnel deformation. Strategic mine design, conservative ground support and proactive monitoring are the main tools to achieve this goal. The performance of underground excavations is adequate when it remains safe and serviceable for its entire intended life, without unplanned rehabilitation and maintenance.

This workshop will explore how current and emerging technologies are employed in the global mining industry to monitor underground excavations and provide the vital feedback loop to ensure they remain safe and serviceable.

In recent years, new and promising technologies, including LiDARs, drones, data acquisition and underground WiFi, can be packaged to enable a better understanding of excavation performance. Some of them have shown very promising results and, as with new technologies, they evolve rapidly.


Workshop Objective and Format


This workshop will examine the current status of different, emerging technologies and how they can be applied to monitor the performance of underground excavations.

The programme is divided into two themes:

  • The morning session will explore the technologies focussing on convergence measurements from repeated laser surveys.
  • The afternoon session will be dedicated to more conventional instrumentation.

For each theme, the format will involve a series of presentations from technology suppliers/developers, as well as from end users at mine sites. Both morning and afternoon sessions will be followed by an open discussion lead by a panel of experts carefully selected based on their extensive experience and knowledge on applying these technologies.


Workshop Facilitator

Professor Yves Potvin
Professor of Mining Geomechanics
Australian Centre for Geomechanics

Yves joined the Australian Centre for Geomechanics at The University of Western Australia in 1998 and was Centre Director, 2000 – 2019. Professor Potvin has published more than 100 articles and is the editor/co-editor of 14 conference proceedings and books. He has over 30 years of experience in rock mechanics and mine design and has previously held managerial positions at Mount Isa Mines, the Noranda Technology Centre and worked as a mining engineer at Noranda Mines, Gaspe Division. Yves undertakes numerous collaborative industry-focussed research projects and is presently involved with the ACG’s Ground Support Systems Optimisation Project, and the Stope Reconciliation and Optimisation Project. He is currently participates in several geotechnical review boards.
