Introduction

The purpose of this course is to provide mine staff the tools required to effectively gather geotechnical data for rock mass classification and rock mechanics design calculations. The majority of rock falls in mine operations are structurally controlled. Design is largely controlled by existing structure. It is critical that site characterization be performed so as to identify the structural factors that would affect rock slope angles, drill and blast design, support requirements, resultant dilution and span design, etc. A good understanding of rock mass structure forms the basis of rock mass classification which is used in the majority of rock mechanics design methods.

Upon completion of the course students are able to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. The focus of the course is towards gathering information for purposes of analysis and design. The goal is to use effective mapping techniques to obtain data that can be used as input for any of the established rock classification systems. All of the commonly used classification values such as Barton's Q and Q' systems, Bieniawski's RMR, Laubscher's MRMR and Hoek's GSI systems are covered.

Learning Outcomes

• Gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis.
• Apply this information to classification systems such as Barton's Q and Q' systems, Bieniawski's RMR, Laubscher's MRMR and Hoek's GSI for subsequent design purposes.
