Course Summary


The collection and compilation of structural geologic information from the field is the basis for a proper understanding of the rock mass as seen from a geologic structure perspective. Whether this is done using conventional techniques or with cutting edge technologies, the requirements are the same. Data must be collected consistently, thoroughly, and with as few biases as possible.

The advent of powerful computer programs allowing 3D visualization of geologic structures properly oriented and located in real space has the potential to revolutionize geologic structural interpretation. While not a "silver bullet", photogrammetry is an exceptionally useful tool in that it allows mapping of areas that are inaccessible and/or dangerous, as well as perspective views and coverage that cannot be obtained with conventional mapping. Orientation, location, and continuity of a structure can generally be obtained much more rapidly, accurately, and economically using photogrammetry as compared to conventional mapping. However, photogrammetry does not replace conventional mapping. Conventional mapping is required to confirm physical characteristics of the geologic structure that can only be ascertained from physical examination as well as to verify photogrammetric interpretations. Additionally, developments in drilling and core orientation, especially using downhole televiewers, now permits reliable interpretation of the location, and orientation, of major geological structure at depth.

The goal of the course is to provide an overview of:

  • geologic data collection utilizing conventional and photogrammetric methods,
  • the required compilation of the collected structural data for analysis, and
  • analysis of the compiled data such that geologic structural frameworks may be completed.

These structural frameworks, or models, can be utilized for a variety of end purposes.

This course will provide a detailed overview of theory and techniques, and while examples will be provided during the course, this cannot be seen as a substitute for "hands on" training in the field.

Pre-Course e-Learning

Prior to the course, registered delegates have access to the online e-learning material consisting of two introductory courses titled: Geotechnical Data 1 - Rock Fabric and Structures and Geotechnical Data 2 - Rock Material Properties.

Certificate in Mining Studies

This course qualifies for 1 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 of interest to geologists and geotechnical engineers, especially those that require detailed structural geologic models for design purposes. It is intended for those who have practical experience in the field and are seeking better methods of collecting data, and interpreting the data they collect. It will require a basic understanding of structural geology, geologic structure genesis, structural data collection procedures (core drilling, core logging, etc), and stereographic projections of structural orientations.

James Mathis

Dr. Mathis received his B.Sc. in Mining Engineering from the University of Nevada Reno and a Doctorate in Rock Mechanics Engineering from the Högskolan i Luleå, Sweden. He has over 30 years of engineering consulting experience in rock mechanics. He holds professional engineering registration in Arizona (USA), Washington (USA), Nevada (USA), Northwest Territories (Canada), British Columbia (Canada), and Queensland (Australia). One of his primary specialties is rock mass characterization, with emphasis on definition and inclusion of discontinuities in statistical assessment of opening designs for rock. His research has been practically applied in a wide range of mining operations, both surface and underground.
