Course Summary


This live webcast will present the principles and applications of stereographic projection techniques commonly used in rock engineering to analyse geotechnical data and to determine the likelihood of rock mass failure induced by geological structures. The principles of projecting the orientation of 3D geological structures onto a 2D grid or stereonet and distribution of structural populations will be demonstrated with interactive figures, examples and exercises. The methodology of plotting, processing, and interpretation of geotechnical data for the purpose of stability analysis of rock slopes and underground excavations will be introduced in the context of various rock mass failure modes.

Pre-Course e-Learning

Prior to the course, registered delegates have access to online e-learning material consisting of an introductory course titled Stereographic Projections.

Certificate in Mining Studies

This course qualifies for one day 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 Concepción. more details »

Continuing Professional Development (CPD)

Registered participants who attend the entire webcast 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 recommended as a prerequisite or refresher course for individuals interested in taking advanced courses in rock engineering, mine geotechnics and underground support design.

Grazyna Chrobok

Grazyna B. Chrobok is a mining consultant with expertise in rock mechanics and mine permitting. She holds a Master's degree in Mining Engineering from the University of British Columbia and the University of Mining and Metallurgy in Krakow, Poland.

Over 20 years' experience in the industry as an engineer and mining technology instructor at BCIT has provided her with practical knowledge of geotechnical investigation techniques, stability assessment of surface and underground excavations, blasting, ground support and mine design.
