SLOPE STABILITY ASSESSMENT IN THE OPENCAST QUARRY IN HAMMAM DALAA (M'SILA, ALGERIA)

The aim of this study is to identify the main factors that affect the site's stability by using the adequate solutions, which help to solve the problems of slope stability at the quarry of Chouf Amar, Hammam Dalaa, Algeria. A large amount of geological, hydrogeological and mechanical data has been collected from the site. We realized the study of the influence of different factors on the safety coefficient. Limit equilibrium techniques have been adapted, taking into account the variability of the site data, to analyze the performance of the existing area of production site. Results solution under different configurations has shown that stability index is highly affected by hydraulic and seismic factors
