  I assumed the role of Department Head for Geological Sciences and Geological Engineering in July

  having joined the Department in July 2001. My research interests include: ground hazards including subsidence and landslides and management of geological hazards and risks. Major research projects include: the Canadian Railway Ground Hazard Research Program with CN Rail

  CP

  Transport Canada and Derek Martin's research group at the University of Alberta; and Bedrock to Blue Sky - a multi-disciplinary project involving universities

  government agencies and companies in Ontario and Quebec to examine the feasibility and viability of sustainable energy retrofits to campus buildings including addition of geothermal and solar capacity and internal power saving measures through the development of accurate simulation and decision support models.

  Klohn-Crippen Consultants

  Based in the Sudbury office

  our major task was preparing Closure Plans for Inco's Ontario Division Mines. I also worked on mine subsidence issues for a substantial number of Canadian mines and in Greece and Slovakia. During this time

  I developed the core structure for the site investigation protocol for assessing mine site geomechanics structures which was included within the Ontario Mining Act Mine Closure Guidelines.

  Funded by a substantial number of mining companies through CSIRO in Australia and the Geomechanics Research Centre at Laurentian University in Canada

  this year-long project resulted in the publication of "Cablebolting in Underground Mines"

  co-authored with Dr. Mark Diederichs. The project allowed us to visit over 50 mines in Canada

  Australia

  Papua New Guinea and the United States

  assessing cablebolting practice - including design

  installation and monitoring

  and provided us the opportunity to work with superb colleagues all over the world

  including Dr. D. McCreath and Dr. P. Kaiser at Laurentian

  and Dr. A. Thompson and C. Windsor at CSIRO.

  Optimization of the mining sequence in terms of economics (maximizing net present value) often leads to multi-front mining methods generating pillars. Significant resources are tied up in these pillars

  but mining them is often challenging. In order to improve our understanding of rock mass behaviour while extracting these pillars

  an extensive monitoring program has been designed and implemented at Vale’s Coleman mine (Sudbury

  Canada). The program focuses on existing and new technologies that have potential for monitoring deformation and rock mass property changes. It includes both active and passive methods: gravimeters

  multi-point borehole extensometers

  fiber optic strain meters

  fixed and portable three-component seismic arrays

  borehole imaging and sonic logging

  and

  repeated LiDAR surveys. This paper reports results from an initial project phase

  when only a small amount of mining has taken place. The goal was to test and compare technologies in order to assess their sensitivity

  accuracy

  repeatability and suitability for underground mining conditions. Value is gained by having a broad range of monitoring devices running side by side

  enabling comparisons and benchmarking.

  Uncertainty plays a critical role in geotechnical design projects. In addition to the inherent uncertainty stemming from the natural variability of geomaterials

  knowledge based uncertainty involving testing

  transformation and modeling errors must also be considered. While several tools are available to incorporate uncertainty into the design process

  most only deal with it subjectively

  which typically leads to an inconsistent estimate of design risk and the selection of overly conservative support systems. Reliability methods

  however

  incorporate the uncertainty in material properties directly into the design process

  allowing for an assessment of system performance with respect to a prescribed failure criterion or mode. This eliminates the need for overly conservative design methods and allows for a more economic design to be selected. This paper presents a standard reliability approach for the design of tunnels and underground works and discusses some of the critical questions that must be addressed to facilitate its incorporation into current practice.
