Fundamental research into rock mechanics and geomechanical behaviour for nuclear waste management has cross-over applications for other sectors, such as tunnelling, trenchless excavation techniques, and oil gas production. Some examples include:

  • Studying stress-induced changes in the excavation damage zone around underground openings to assess the implications for civil tunnels, pipelines and wells
  • Exploring the limitations of mechanical excavation techniques in pipeline applications based on mining experience
  • Investigating thermally-generated borehole breakouts in large-diameter boreholes in granite to understand the implications for oil gas applications
