Course Summary


The ultimate objective of the course is to assist the mine operator in making decisions employing sound geotechnical input.

This course provides the operators of underground mines with the tools required to make on site pillar and opening stability assessments. Tools for assessing opening stability are provided. Empirical methods for considering the complex interaction of stress, opening geometry, structure and rock mass are provided. Ample time is given for solving stability problems and participants are strongly encouraged to bring case histories or questions from their own operations. Case history data should include stope or pillar geometry, depth, estimated stress levels as well a description of the rock mass (bring photos if possible).

You will learn how to:

  • Make decisions on site stability assessments of openings and pillars
  • Develop an understanding of the critical field data required for stability assessment
  • Judge the influence of rock mechanics on the stability of planned openings
  • Understand the influence of rock mechanics on overall mine design

For details of topics covered see course schedule.

This course has been given to over two hundred participants throughout North America over the last ten years and is recognized by mining operations in Canada as providing "common core" training for onsite personnel in the field of rock mechanics.

Pre-Course e-Learning

Prior to the course, registered delegates have access to online e-learning material consisting of two introductory courses titled Design for Underground Metal Mines 1 - Design Parameters and Design for Underground Metal Mines 2 - Design Guidelines, authored by Dr. Rimas Pakalnis.

Certificate in Mining Studies

This course qualifies for two days of short course credit for the Certificate in Mining Studies (CMS), a continuing education program of accredited short courses, webcasts and online courses for lifelong learning in mining, supported by University of British Columbia, University of Arizona and University of ConcepciĆ³n. more details »

Continuing Professional Development (CPD)

Registered participants who attend the entire short course and complete an evaluation at the end of the course will receive a Certificate of Attendance, confirming the Professional Development Hours (PDH)/Continuing Education Units (CEU) earned. Please confirm with your employer and/or professional association that this course qualifies for CPD.

Who Should Attend?

The course is directed at ground control, mine planning and chief engineers/geologists.

Dr. Rimas Pakalnis

Dr. Pakalnis is an emeritus professor with the University of British Columbia, Mining Department, in Canada, and has consulted to over 175 underground mines throughout the world. He has authored over 100 papers and is instrumental in the development of underground design methodologies in rock mechanics that are being used universally.
