Caving Prediction
Itasca Consulting Group, Inc. and ASC (Applied Seismology Consultants) are in an ongoing partnership to apply advanced numerical modeling tools and microseismic data analysis techniques to caving prediction. Itasca studies rock mass strength and brittleness, using the Particle Flow Code (PFC) to create and test "Synthetic Rock Mass" samples (SRM) and subjecting these to induced stresses expected in situ.

Rock + Dam Analysis
To improve monitoring of the Bin El Ouidane dam, built in 1952, Itasca Consultants S.A.S. (Ecully, France) was asked by INGEMA to conduct a FLAC3D analysis of the behavior of the "dam + rock" system with respect to seasonal temperature variations and water level changes in the reservoir.

Fracture Zone Study
In a project for SKB, Itasca Geomekanik AB conducted a detailed study of a minor fracture zone at the Äspö Hard Rock Laboratory. The goal was to increase knowledge of the geological and geometrical structure.

Tunnel Infrastructure
Itasca Consulting Group, Inc. has conducted several 3D stability analyses of complex geometry tunnel infrastructure for road as well as rail tunnels by applying both the continuum code FLAC3D and discontinuum code 3DEC. Innovative analysis techniques were developed to demonstrate that the total utilization of all rock bolts is quite low with respect to characteristic strength and strain capacities.

Behavior of Repository Tunnels Support
Numerical modeling was used to compare the support stability for tunnels in two potential nuclear waste disposal sites; the sites had varying rock properties, emplacement depths and storage geometries. The tunnels were excavated using a Tunnel Boring Machine (TBM).

Depressurising an Underground Ore Body at the McArthur River Mine
Pre-mining depressurising of a deep ore body at the McArthur River mine in northern Saskatchewan was considered to decrease the risk associated with mining near 5 MPa water pressure and increasing the amount of ore that can be extracted.

Itasca is pleased to announce that as of May 1, 2009, Applied Seismology Consultants (ASC) is an Itasca International company. ASC is a world leader in microseismic monitoring services and has developed, in partnership with Itasca, a new discipline called "Fracture Network Engineering." The combined companies will seek to explore the exciting potential of this discipline with clients throughout the world.
Itasca is an official sponsor of Rock Slope Stability 2009. “Rock Slope Stability 2009 will provide a forum for open pit mining and civil engineering practitioners, consultants, researchers and suppliers worldwide to exchange views on best practice and state-of-the art of rock slope technologies.” — Slope Stability 2009
