Abstract
Cankiri rock salt formation is one of the most important rock salt sources of Turkey. Rock salt production in this area is performed by underground room and pillar mining method approximately 150 m under existing topography. However, pillar dimensions which are used in Cankiri rock salt mine are determined by trial and error method. Aim of this study is to create a model which will overlap long and short term rock mechanics analysis results with in-situ stresses and in-situ deformations. By the evaluation of these results pillar dimensions were determined by numerical methods. Numerical analyses were carried out with PHASE(2) software which uses a hybrid numerical modeling method. Firstly the pillar dimensions applied at the present time were investigated then different pillar dimensions were tested in order to investigate the boundary conditions of safe pillar dimensions.
