Course Summary


Geotechnical Data 1 - Rock Fabric and Structures is intended as both a course and a technical reference for an audience of mining engineers, engineering geologists and geotechnical engineers concerned with underground and surface excavation in rock.

This course introduces the user to data collection for rock fabric and major geologic structures using stereonets, mapping and core logging techniques. It introduces the concept of rock mass classification for excavation design and discusses the importance of the geologic regime, rock fabric, rock strength and other properties. The course provides practical guidelines and procedures for collection of relevant geotechnical data by stereonets, cell mapping, core logging, and reduction of data for rock mass classification purposes.

Geotechnical Data 1 - Rock Fabric and Structures, and its companion course Geotechnical Data 2 - Rock Material Properties, replace and expand upon the original course Geotechnical Data Collection for Excavation in Rock by the same author.

Course Content

The course comprises 14 learning sessions of 30-60 minutes each at both summary and text level, plus multiple-choice reviews, extensive worked examples, and numerous illustrations and supporting tables. Course duration is equivalent to approximately 11 hours of study content.

Learning Outcomes

  • Explain the principal data collection methods for excavation in rock.
  • Plan a data collection campaign and apply these data collection methods in practice.
  • Discuss and apply the models and procedures presented for data reduction and interpretation.

Recommended Background

  • A degree in mining or geotechnical engineering, engineering geology or related discipline.
  • Experience with underground and/or surface excavation in rock.

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.
