Between 1987 and 2015, he was Chair for Rock Engineering and Ground Control at Laurentian University and in 1997 became the Founding President of MIRARCO-Mining Innovation. Between 2007 and 2014, he was seconded to lead the Centre for Excellence in Mining Innovation (CEMI) and then the Rio Tinto Centre for Underground Mine Construction (RTC-UMC).

      He is the author of more than 350 technical and scientific geomechanics publications and has received awards from the International Society for Rock Mechanics, the Canadian Geotechnical Society and the Canadian Institute of Mining. He is a Fellow of the Engineering Institute of Canada (EIC) and the Canadian Academy of Engineers. In 2013, he was awarded the Julian C. Smith Medal of for his “Achievements in the Development of Canada” and was named the “Tunneller of the Year” by the Tunnelling Association of Canada.

      He is a specialist in applied research for underground construction and mining with primary interests in rock engineering, rock support in burstprone ground, mine design and the application of innovative technologies to increase mine safety and productivity. He brings extensive experience from both the industrial and academic sectors, having served as consultant to numerous consulting companies, mines, and public agencies. He has supported contractors, mining companies and public sector clients during Coroner’s inquests and litigations.

      For the economic and safe construction of deep tunnels, a contractor has to be presented with efficient and effective support systems, i.e., support classes that can be rapidly installed and are effective in managing stress-fractured ground. For this purpose, it is necessary to properly anticipate the actual rock mass behaviour and to provide flexible but reliable means of ground control. In mining, mining-induced stresses changes further damage rock near excavations and excessive rehabilitation often causes undesirable delays and costs. In these situations, a deformation-based support design approach is needed to prevent overloading of the rock support system by excessive deformations and to sequence the support installation for optimal support performance.

      In practice, robust engineering approaches have to facilitate cost-effective construction processes by ensuring that all construction tools work well.
Within this framework, the lecture will focus on four technical aspects and the author draws on experiences in deep mining and Alpine tunnelling. Findings from collaborative research and “real world” experiences are merged to highlight sound engineering design practices that respect the reality of construction and the demand for workplace safety.


    • ARMA 16-MTS lecture – Underground rock engineering to match the rock’s behaviour

      – Challenges of managing highly stressed ground in civil and mining projects (Executive Summary)

      by Peter K Kaiser

      Abstract
      In the spirit of the conference theme of the 50th US Rock Mechanics Symposium, this lecture addressed one of many prerequisites for “exciting advances in rock mechanics”, i.e., the need to fully comprehend the rock mass behaviour before solving “practical issues” in rock engineering.
In most engineering fields it is possible to select the best fitting, artificial materials for a given engineering solution. In rock engineering however, a misfit between the behaviour of a natural material, the rock, and a chosen engineering solution often leads to serious complications with costly project delays or rehabilitation works and sometimes with unacceptable safety risks.
      Proper rock engineering means to fit the engineering solution to the actual rock mass behaviour!
Overcoming the challenge of matching the rock behaviour with meaningful engineering models and design parameters is therefore a prerequisite for advances in rock mechanics and for successful rock engineering. This lecture highlights some recent advances in understanding rock mass behaviour for the design and construction of underground excavations.

    • 13th ISRM lecture 2016 – Challenges in rock mass strength determination for the design of underground excavations

      by Peter K Kaiser

      Abstract
      Rock mass characterization for deep underground construction and mining offers many challenges. This lecture builds on a paper presented at the 2015 ISRM Congress in Montreal. It first describes some of the key challenges when characterizing rock and then offers guidance on how to arrive at reliable rock mass strength parameters for the engineering design of deep underground excavations.
The limitations of various available rock mass classification systems, developed for excavation stability assessments and support selection, and rock mass characterization systems, developed for the purpose of rock mass strength determination, are also briefly discussed.
      The main part of the lecture deals with rock mass characterization for strength determination and on practical implications for the design of deep underground excavations. It is illustrated how common practices in the use of available rock mass characterization systems often tend to underestimate the rock mass strength, particularly when well confined at depth. Improvements to currently adopted approaches are presented to help overcome these challenges.
The practical relevance of reliable rock mass strength determination is illustrates by case examples from civil tunnelling and mining applications.
