Consulting services and activities
Maintaining close contact with current practice and issues in the mining industry is an essential factor in maintaining up to date content in courses, and in identifying relevant research topics. For these reasons, I maintain consulting activities, principally in the area of rock mechanics applied to mine design. However, since my primary job is at the university I have limited time for consulting work, so my preferred mode of consulting is on a review basis. For larger projects I often work with other consultants or companies to provide a larger range of services. Where appropriate, I also involve my graduate students in consulting under my supervision as this provides them with valuable work experience.
Main areas of expertise:
- Rock mechanics program review
- Numerical stress analysis
- Geomechanics applied to open pit and underground mine design
- Ground support
- Geomechanics of mining in deep and high stress conditions
- Mining induced seismicity
- Planning of field investigation programs, and interpretation
- Instrumentation programs and data analysis
