Tryana Garza-Cruz

General Manager, Principal Geomechanics Engineer

Dr. Garza-Cruz is a geomechanics engineer with 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.

She 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.
