SummaryAt an open-pit mine, ore production has been processed with forming slopes. At this type of mining enterprises, permanence of the production can be realized depending on the stability of the slopes. Region of Marmara of TKI (General Directorate of Turkish Coal Enterprises) which is the subject of the project is faced sometimes with production intermittent due to slope instabilities. The aim of the project is to determine the displacement and subsidence on the slopes and their vicinity from InSAR images in junction with ground control stations measured by static GPS technique and equipped with corner reflectors, and to take precautions for any possible collapse giving recommendations for reinforcement and stabilization. The modeling of the velocity of the slopes with comparing in situ measurements will be obtained. During modeling the methods of finite elements and boundary elements will beused. In the project, movements of the slopes will be followed and these movements will be used to provide a database of stabilizing model through determined displacements using the advanced techniques of the interferometric SAR and GPS measurements. The determination of a model is an essential work in order to follow slope slides. With the model, movements and stability problems will be sent to the mining administrative so that necessary precautions can be taken.
