Numerical modelling is an important tool for mining and civil geomechanics. When properly calibrated, numerical models are capable of simulating construction methods or mine plans in order to predict rockmass deformation, the severity of seismicity and potential for rockbursting over the project life. These predictions can then be used to identify potential risk for damage to critical infrastructure, and for ensuring personnel safety.
This workshop will focus on the types of qualitative and quantitative data that can be utilized for model calibration, and provide participants with an invaluable toolbox of procedures and methods for calibration of numerical models.
Numerous case studies will be presented to demonstrate the techniques and approaches being taught in this course.

Distinct Element Modeling of Fractured Rock
This one-day workshop will discuss numerical simulation of fractured rock masses using the distinct element technique. The following topics will be covered:
- Introduction to the distinct element method
- Numerical representation of rock
- Continuum vs discontinuum
- 2D vs 3D
- Polygonal blocks
- Rock properties
- Equivalent continuum and the Geological Strength Index (GSI)
- Joint properties
- Stiffness and strength
- Adding joints and fractures
- Mapped faults (deterministic)
- Discrete Fracture Networks (stochastic)
- Modeling considerations
- Initial and boundary conditions
- Model results interpretation
- Rock mass failure
- Joint slip
- Practical example: Open pit mine
Facilitator: Jim Hazzard, Product Manager - 3DEC
The hybrid finite-discrete element method (FDEM) is an explicit numerical approach which combines continuum mechanics principles (FEM) with discrete element algorithms (DEM) to simulate multiple interacting deformable and fracturing bodies. With its ability to qualitatively and quantitatively reproduce failure processes in brittle materials, FDEM is gaining increasing acceptance in civil, mining, geological, and petroleum engineering applications, where fracture and fragmentation processes are key to fully understanding the rock mass behaviour.
This workshop will combine theoretical lectures on the fundamental principles of FDEM with practical modeling sessions where participants will be guided through several simulation cases. The workshop will start with a general introduction to the FDEM modelling philosophy and its application to engineering geology, rock mechanics, and geophysics problems. After a quick review of the basic algorithms, such as element deformation, contact detection, and contact interaction, the fracture model will be discussed in more depth. More advanced features of the FDEM code, including: in-situ stress initialization, rock excavation, and the incorporation of rock-reinforcement and Discrete Fracture Networks (DFNs) will also be introduced. In the second part of the workshop, participants will gain valuable “hands-on” experience through a series of practical modelling exercises using Geomechanica’s FDEM software (FEMDEM).

This workshop will comprise a series of lectures, discussing seismic hazard mechanisms and techniques for modelling mining induced seismicity and its effects.
We will discuss experiences at operating mines and the evolution of modelling approaches over the last 20 years concluding. We will show how modelling, mine management and monitoring can be integrated to minimise risk and maximize productivity, and we will talk about some of the mistakes that have been made along the way. The session will conclude with a discussion of todays state of the art and a discussion of what we need in the future.
The analysis will be presented using examples from mines, from mine scale forecasting, to ground support capacity analysis, to forensic back analysis.
