Michael Davies, P.Eng./P.Geo, has a B.A.Sc. in Geological Engineering, a M.A.Sc. in Geotechnical Engineering and a Ph.D. in Civil Engineering (Geotechnical). He has over 25 years experience related to mining. He has worked on projects throughout North, Central and South America, Southeast Asia, Australia, Africa and Scandinavia. His project experience includes:
- Mine Waste Management - evaluation, design, and closure plans for tailings impoundments and mine rock dumps with particular expertise with co-disposal (tailings/rock) and dewatered tailings (thickened, paste, and filtered);
- Open Pit Mining - evaluation and design for coal and hard rock mining including tropical environments (saprolites/laterites)
- Risk Management - decision analyses, facilitation and risk assessments related to all stages of the mining life cycle.
Dr. Davies has authored/co-authored more than 50 papers in conference proceedings, journals and texts on mine waste management. He has particular interest in mine tailings failure case histories and was awarded a Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Distinguished Lecturer Award in 2000 for his work in this field.
Jack Caldwell, P.Eng, has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Canada and the United States. His project experience includes:
- mines and waste disposal facilities - design, construction supervision and reclamation of tailings impoundments, mine rock dumps, heap leach pads, landfills and radioactive waste disposal units;
- hazardous and radioactive waste site remediation - senior management and technical consultant
- landfills - design, construction, operation and closure with special focus on liners, covers, and soil reinforcement.
In addition, Mr. Caldwell has been the lead specialist for various geotechnical and civil engineering projects in Southern California. Mr. Caldwell has written many engineering reports, proposals, and technical papers. He is the lead author of the book, Principles and Practice of Waste Encapsulation, on the design of waste disposal facilities for radioactive and hazardous wastes.
Lawrence Charlebois is an active Engineer-in-Training (EIT) in the province of British Columbia. He holds a B.Sc. in Geological-Environmental Engineering and is a M.A.Sc. candidate in Mining Engineering with the University of British Columbia. As a practicing EIT, his project experience includes:
- Soils and rock mass characterization
- Contaminated sites investigation
- Water balances for tailings facilities
- Analytical and numerical modelling of groundwater flow and contaminant transport in mining environments
- Tailings drying and strength characterization
Recently, Mr. Charlebois has focused his research attention on the rheological-geotechnical behaviour of flocculated tailings flows and their depositional characteristics on sub-aerial beaches.
