Course Summary

Introduction

The Design for Underground Metal Mines courses have been written with the mine operator in mind. Numerous conferences, papers and texts have been written on the procedures to gather and analyze data for implementing into a design process. Although there is wide experience and expertise in the design of mine openings, it has not previously been compiled into courses that enable users to engineer their work place based upon past experience and practice augmented by sound engineering principles.

Mining is a dynamic process which requires in excess of thousands of cubic metres of openings to be developed daily over the life of a mining operation. Those openings may be for development and/or production purposes, however all cases must be designed so as to ensure the required behaviour. The site engineer therefore, must design the mine opening or pillars after addressing all issues relevant to the design and assessment of the overall behaviour.

These courses are designed to give the operator a design procedure that has been developed in conjunction with academia and practicing operations. This design procedure has been implemented at over twenty underground metal mines around the world. The courses reference numerous authors in the field and apply their findings to arrive at tools for design. The geomechanics design group at the University of British Columbia has been instrumental in developing the design curves presented here along with the direction and sponsorship of CANMET and mining operations throughout Canada.

Design Parameters is the first of two Design for Underground Metal Mines courses by the author. The companion course is Design Guidelines.

Design Parameters provides the necessary background, in terms of input parameters for stress, structure, rock mass characterization, failure criteria and support procedures, for the design principles presented in the companion course.

Content

Design Parameters is structured as three parts...

  • Stress and Structure
  • Rock Mass Characterization and Failure Criteria
  • Support and Monitoring
The course comprises 11 viewing sessions at both summary and text level, plus multiple-choice reviews, and numerous figures, design tables and references. Course duration is equivalent to 12 hours of viewing content.

Learning Outcomes

  • Discuss data collection, implications and applications of the parameters on which the design of mine openings for underground metal mines is based.
  • Discuss the determination of in situ and induced stresses for underground mine openings.
  • Discuss data collection methods for geological structure and the influence of structure on the stability of mine openings.
  • Discuss the RMR and Q systems for rock mass characterization and their application to design of mine openings.
  • Discuss the derivation and application of appropriate failure criteria for design of mine openings.
  • Discuss the application, advantages and disadvantages of the different types of support available for ensuring the stability of mine openings.
  • Apply the knowledge gained to practical investigation, analysis and design of underground mine openings.

Recommended Background

  • A degree in mining or geotechnical engineering, engineering geology or related discipline.
  • Experience of mining operations for underground metal mines.

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.
