This technical presentation is primarily for engineers, geologists and geoscientists who are actively involved in the geotechnical assessment of fractured rock masses in the mining and infrastructure industries.
This webinar will explore the integrated FracMan DFN methodology and workflow for the characterisation and analysis of naturally fractured rocks. The presentation's three main sections report on the Discrete Fracture Network (DFN) method and use:
- The first section focuses on an overarching approach, covering a brief history of the approach, its basic philosophy and typical methodology, as well as outlining data and characterisation requirements of the approach.
- The second section considers strategies for obtaining key rock mass mechanical descriptions including block size distributions, rock mass measures such GSI values and key effective rock mass property values.
- The final section reports how DFN description can be carried forward to perform insightful geotechnical analysis considering in situ stress prediction, kinematic block stability analysis for benches/slopes and tunnels, excavation analysis, and support strategies such as grouting and bolting etc.
These workflows are considered key to underpinning the characterisation process as well as the optimised design and construction phases of underground developments.
