Mining operations at the Kristineberg Mine approaches depths of more than 1200 m. Severe ground conditions are consequently expected due to the combination of weak rock formations and relatively high in-situ stresses which are making the ground support installation inevitable. The applied support technique, however, is not unique and varies depending on the ground deformation characteristics, i.e. failure type and magnitude. On the other hand, the complex geology of the mining zone induces different types and magnitudes of failures as the rock types and locations vary at different levels of the mine. As a result, to improve the support performance, the possible ground conditions which may be arising from varieties of geological parameters at the mine need to be known. This work aims mainly at studying the ground deformation characteristics against some of the most probable geological scenarios at the mining zone. The study is performed through numerical modeling of an unsupported stope by FLAC2D; the required input data is determined based on the observations and literature, the proper modeling approach is identified and the modeled deformation behavior of the stope is studied through so-called “Parameter Analysis”. The results of this analysis can be used, then, for further numerical simulations of the supported stopes.
