Material Detail
Estimating Rock Mass Strength Using the Hoek-Brown Failure Criterion and Rock Mass Classification
This report constitutes part of a joint research project between Boliden Mineral AB and Luluea University of Technology, concerning large scale slope stability in open pit mining. The project is aimed at developing a design methodology for large scale rock slopes, with special application to the Aitik open pit in northern Swedan. In this report, the history of the Hock-Brown failure criterion is reviewed, and its validity discussed, with particular application to the design of large scale rock slope. The report specifically deals with strength estimation for the Aznalcollar open pit mine in Spain. These strength estimates will serve as input to numerical modeling and limit equilibrium analysis of the footwall stability at Aznalcollar, which will be described in a subsequent report.
