This paper explains how a large Underground Crushing Chamber of 140m 2 of section and 35m length has been preliminary designed and optimized by applying a combination of two geotechnical well-kwon software: A 3-dimensional boundary element stress analysis as EXAMINE 3D and finite element modeling program as PHASES 2D. The first one allows us to know the correlation among the main void and the auxiliary ones, the vertical shaft and the haulage tunnel. Secondly the Finite Element Program will show the extension of the plasticizing zone around excavation. Thanks to the easy preparation of the models, this methodology enables us of making decision related to the preliminary design, knowing as well the previewed deformations. © 2014 Taylor & Francis Group, London.
