Dr. Erik Eberhardt

Erik Eberhardt is a Professor of Rock Mechanics and Rock Engineering, and the Director of the Geological Engineering program at the University of British Columbia. His research focuses on the integration and advancement of field geology, innovative geotechnical monitoring and state-of-the-art numerical modelling applied to underground excavation and deep mining problems. His research is driven by a recognition that the tools frequently used in assessing risk are often descriptive and qualitative, and that there is a need to better understand the underlying mechanisms responsible for complex rock mass responses to engineering activities. Erik is a registered professional engineer and consults on international projects in North and South America, Europe and Asia. He has published over 200 technical papers, and was the 2013 recipient of the John A. Franklin Award for outstanding technical contributions to rock mechanics and rock engineering, and 2017 recipient of the Thomas Roy Award for outstanding contributions to the field of Engineering Geology in Canada.

Erik was the Associate Director of the Rio Tinto Centre for Underground Mine Construction (RTC-UMC), a state-of-the-art knowledge centre tasked with developing and implementing innovative step-change technology designed to improve mine safety and create value by mitigating geo-risk. He has led numerous industry-sponsored research initiatives related to block caving, including those investigating mining-induced subsidence, cave interactions with open pit slopes, rock caveability and fragmentation, rockburst hazard and mitigation, and wet muck spills and mudrush hazards. He helped establish the International Caving Research Network (ICaRN), focussing on rockbursting and mudrush hazards in deep caving operations.
