About Itasca

New ICG General Manager

Dr. Tryana Garza-Cruz is a Principal Geomechanics Engineer who has been with Itasca Consulting Group since 2011. She has experience in the application of three-dimensional continuum and discontinuum numerical methods to assess the stability of mining excavations, caveability, extraction level performance, surface subsidence, primary fragmentation, and stope-back behavior, as well as to evaluate underground mining methods and understand the creep behavior of excavations in frozen ground.

Dr. Garza-Cruz has applied numerical models to formulate recommendations on mine design criteria (pillar, room, stope, and panel dimensions), as well as regional barrier-pillar and crown-pillar dimensions, sequencing, and set back of infrastructure and accesses. She has also developed specialized tools using Bonded Block Models in 3DEC for the study of spalling rock mass response at tunnel scale.

Dr. Charles E. Fairhurst, ICG's past General Manager, will now be focusing all of his efforts as CEO of ICG's parent company, Itasca International, Inc.
