Lecture Abstract
Approaches for Interpreting Instrumentation and Mapping Data for Rock Mechanics Design
Stable underground mine design relies on data and judgement to estimate rock mass properties, stress conditions and opening geometry behaviour. The data can be obtained through detailed data collection and local instrumentation programs coupled with numerical modelling. This approach can be expensive and provides detailed data on very localized conditions of an often highly variable rock mass and stress regime.
This presentation highlights the value of ongoing simple instrumentation and mapping techniques. Basic rock mechanics theory is coupled with simple interpretations to estimate material properties and stress conditions. When the collection, interpretation and application of the data is conducted on site, valuable information is obtained on the variable reaction of the rock mass and stress regime to continued mining. The data and methodology in this presentation are based on over 20 years of graduate student projects at the University of Saskatchewan. The approach presented follows work done by Dr. Rimas Pakalnis, University of British Columbia, and many others from UBC and the Noranda Technology Centre.
