Numerical modeling of three cases (Fuka Mine,Okayama;Shouda Mine,Okayama;Tokiwa Mine,Fukushima) of mining in Japan using FLAC (fast Lagrangian analysis of continua) is introduced to evaluate the stability of hilltop excavation. Ubiquitous joint model is adopted to account for the presence of weak planes,such as weathering joints,bedding planes,in FLAC Mohr-Coulomb model. By studying the distribution of stress,displacement and safety factor,the stability of excavation can be evaluated and new suggestions based on the numerical modeling process can be presented. Further consideration and methodology of the numerical modeling method are also discussed.
