IMS Seismological Course
Sunday 26 March 2017 | Novotel Perth Langley, Perth, Western Australia
Mira Geoscience Workshop: Data Integration Strategies for Deep Mining Hazard Assessment
Sunday 26 March 2017 | Novotel Perth Langley, Perth, Western Australia
Monday 27 March 2017 | Langley Room, Novotel Perth Langley, Perth, Western Australia
Hardrock mines in deep and high stress environments often require the use of seismic systems to enable operators to manage seismic risk posed to the workforce, the mining investment and environment. Seismic data is also used in assessing the rock mass response to mining activities where source parameters are used in the interpretation of rock mass failure mechanisms, the calibration of numerical modelling, and the interpretation of failure mechanics of the rock mass.
High quality seismic databases are of the utmost importance. In rock engineering the transfer of empirical knowledge from one site to another, or between different time periods at the same site, is crucial for good decision making in complex situations. The complexities involved in the design, installation and maintenance of seismic systems and the challenges imposed on processing the data can result in noise and poor quality data contaminating the databases; adversely impacting on decision-making.
The workshop will provide a forum to discuss the different aspects that impact on data quality with the following aims:
- To provide mine site rock engineers and seismologists with practical knowledge to ensure the highest quality data for the site
- To identify problems impacting on the industry which need to be addressed with focussed R&D
Due to the wide range of aspects that contribute to seismic risk in mines, the workshop will cover the following:
- Global case studies, including data quality issues
- Best practice for system design, maintenance and data QA/QC
- Dealing with noise (orepass or crusher noise and blasts etc.)
- System auditing
- System effect, assumptions and algorithms
Who should attend
All users of mine site seismic data.

‘Geotechnical engineers can have their seismic data cake and eat it too’
A graduate of the University of NSW in Sydney Australia in 1980, Dr Peter Mikula worked for ACIRL Ltd, Coffey Partners International, and Mt Charlotte Gold Mine, Kalgoorlie. At Mt Charlotte for 12 years, Peter became very conversant with various issues including seismicity and large underground stope stability. He was also a key player in mine safety, accident investigation, and risk management. In 2005 Peter formed Mikula Geotechnics Pty Ltd, a geotechnical consultancy working in underground hard rock mines, with increasing emphasis on seismicity, dynamic capable ground support, and the need for data to support engineering design. He has authored or co-authored over 50 professional papers.
Gerhard Morkel Australian Centre for Geomechanics
‘Case studies — investigating the seismic data quality at mines’
Gerhard joined the ACG in 2014 as a research engineer for the ACG’s Mine Seismicity and Rockburst Risk Management Project. Gerhard graduated from the North-West University with an MSc in Physics in 2008. After finishing his studies Gerhard joined IMS, working in the operational aspects of mine seismology. In 2009 he joined Anglogold Ashanti, where he was involved with the seismological aspects of their Western Deep level mines. During this time, Gerhard completed his Chamber of Mines, (South Africa) certificates in Strata Control and Rock Mechanics (metalliferous). In 2012 Gerhard relocated to Australia where he worked as a seismologist/ geotechnical engineer for Kanowna Belle Barrick. Gerhard has more than five years of experience in the seismological and geotechnical aspects of high seismically active underground mines.

Professor Phil Dight Australian Centre for Geomechanics
Phil has been involved with the development and design of ground support for mining applications since 1975. He was a partner in BFP Consultants until BFP was acquired by Coffey Mining. Phil has extensive consulting experience in the geotechnical aspects of the mining industry, and has worked on open pit and underground metalliferous mining problems. In 1985 he was awarded the Manuel Rocha Medal by the International Society of Rock Mechanics for his work in open pit mining and use of ground support to improve pit stability. His ground support algorithm has been adopted by Rocscience in its evaluation of ground support in Phases®, and a variation had been adopted by ITASCA in the Bonded Block Model. In the 1980s with Dr Peter Fuller, he undertook research into ground support work in a number of AMIRA sponsored projects based on open stope mining. Much of that early research work has now been formalised in the literature by others. Phil joined the ACG in 2008 and has since been working on stress memory effects in rocks, ground support applications, slope stability problems (including the use of microseismicity to understand failure mechanisms), and 3D rock properties. Most recently, Phil commenced a four year MRIWA project aimed at investigating the issues of strainburst vulnerability in underground mines.
