Ensuring High Quality Seismic Data for the Mining Industry Workshop

Monday, March 27, 2017 - 12:00am to 11:45pm

Monday 27 March 2017  |  Silver 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.

Workshop Presenters

Professor Savka Dineva Lulea University of Technology, Sweden
Professor, PhD

‘Routine seismic source parameters in underground mines in Sweden – limitations and problems’

Savka is a Professor in the mining and geotechnical engineering division of the Lulea University of Technology, Sweden and an Adjunct Professor at Queen’s University, Canada. In 1978, Savka completed her Masters Degree in physics at Sofia University, Bulgaria, and her PhD in physics/mathematics (seismology) in 1986 at the O.Yu Schmidt Institute of Physics of the Earth, Russian Academy of Sciences. Savka was a research associate at the Geophysical Institute of Bulgarian Academy of Sciences from 1986 to 2000 before becoming a research associate and Adjunct Professor at the University of Western Ontario from 200 to 2007. She was an Assistant Professor at Queens University until 2010 before taking on her current roles. Savka undertakes research in mining and rock engineering and has authored or co-authored 44 publications.


Dr Dmitriy Malovichko Institute of Mine Seismology
Director and Head of Applied Seismology

‘Detecting problems in the configuration of the seismic system (misorientation and mislocation of sensors, wrong site responses and local site effects, inappropriate velocity model) and their effect to the interpretation of seismic data’

Dmitriy has a degree of candidate of phys.-math. sciences (PhD) from the Institute of Physics of the Earth (Moscow, Russia). Between 2000 and 2009 he worked in the Mining Institute (Perm, Russia) and was involved in regional seismic monitoring, local seismic observations in potash mines and karst caves, and engineering seismology projects. In 2009 he joined ISS International (South Africa) which later transformed into the Institute of Mine Seismology (Australia, South Africa and Canada). There he is responsible for seismological services for mines (processing and interpretation of seismicity, investigation of large seismic events) and is involved in research projects in mine seismology. Dmitriy enjoys inferring information about seismic sources and properties of the rock mass from seismic signals. He is also interested in integration of seismic monitoring data with stress modelling.


Dr Peter Mikula Mikula Geotechnics
Director – Mikula Geotechnics

‘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
Research Engineer

‘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.


Dr Ted Urbancic ESG Solutions, Canada
Chief Technology Officer, ESG Solutions

“Uncertainty, precision and errors in microseismic event locations and their interpretation”

Dr. Ted Urbancic, a founder and current Chief Technology Officer at ESG Solutions, has over 30 years of experience examining and interpreting microseismicity associated with mining and petroleum applications. He is a pioneer in the development of microseismic monitoring in industrial applications, authoring over 150 publications ranging from understanding the fundamental aspects of microseismicity to characterizing rock and reservoir behavior by integrating microseismic data with numerical modeling, engineering and geomechanical data. Over the past 15 years, Ted has been integral in building ESG’s microseismic hydraulic fracture monitoring capabilities and in promoting microseismic tools for enhanced reservoir characterization. Currently, Ted oversees work by ESG’s Innovation and Technology Group, which spearheads all R&D related to microseismic analysis in the mining and oil & gas sectors. Ted holds a Ph.D. in Seismology from Queen’s University, Kingston Canada. He is a member of numerous professional societies, including SPE, SEG, AGU, SSA, and EAGE and was recently on the organizing committees for the 2014 and 2016 EAGE Passive Seismic Workshop.
