Design by Measurement Philosophy
► The verification of a rockbolt system design by monitoring, measurement, and observation.
► The basis of the method is to understand the roof and rib deformation mechanisms.
► This can be achieved using in-situ strata deformation monitoring, rock-bolt support loading, and an assessment of the site conditions.
► The purpose is to optimise the rockbolt design so that is both effective and efficient in ground support. Mining, consultancy, support, rock stress measurement, instrumentation, CSIRO Cell, training, instrumentation, extensometers,
Understand Failure Mechanisms – Use an Effective Rockbolt System – Design by Measurement – Monitor the System – Use Real Data to Validate Computer Models.
Understand the environment we are working in
► Geotechnical Assessments
► Rock Properties and Structure
► In Situ Stress
Measure and Monitor Rock Mass Behaviour
► Use instrumentation to define failure ► criterion
► Telltales
► Extensometers
► VW Stress Cells
► Strain Gauge Bolts
► Both Safety and Design Monitoring
Use Appropriate Support Consumables and Test Performance Criteria
► Ensure Support Consumables are ‘Fit for ► Purpose’
► Test - Monitor - Optimise
► Train Operators and Supervisors ► concerning installation and quality control standards
