摘要：

This paper presents the project of improvement of the management of underground mine (mine of Draa Sfar, Marrakesh, Morocco), and its first scientific results, Draa Sfar mine is ranked among the deepest mines in North Africa. Currently, violations depths exceed 1,100 meters. Thus we are witnessing the instability phenomena of land which demonstrate the failure of retaining quote some areas. The most frequent problems of instability especially problems of rock falls due to non-resistance depending bolts and buckling of attack galleries siding with a direction parallel to the foliation. The object of this project is the development of original and reliable models, designed by analytical and empirical learning, dedicated to the relation support-stability stability of underground structures. These models will be integrated into the channel of exploitation of the mineralized deposit.
