Analysis EDZ using verified numerical models (FLAC3D)
Staš, Lubomír ; Waclawik, Petr ; Gong, Libin
Based on the obtained geotechnical and laboratory data, the extent and character of Excavation Damage Zone (EDZ) was simulated using static and dynamic models in the commercial software FLAC3D. The commercial program Fast Lagrangian Analysis of Continua in 3 Dimensions (FLAC3D) (Itasca Consulting Group 2012) was adopted to analyse the EDZ of Rozna Mine roadway. The analysed profile is located on the roadway No. Z3-XX in an environment formed mainly by migmatized biotite to amphibole-biotite pararules. The dynamic mode simulate using of blasting method. The research report summarize results of numerical simulation of EDZ in high anisotropic rock mass.
