Treatment Technology and Stability Analysis of Dump Slope in Open Mine

In order to obtain the law of Yinwan dump deformation and failure of slope and propose targeted control measures, this paper discussed the causes of Yi nwan landslide, based on the existing geological data and on- site displacement monitoring results from the surface GPS. Then, it analyzed the safety of the slope usin g FLAC3D software, and studied the failure mechanism to the creep slope. Combination with the engineering practice, considering the creep areas near to the influence of soil on the slope stability, and through to the two kinds of earth pressure foot for slope stability under the limit equllibrium analysis, the paper put forward cloudy bay I andslide governance measures and subsequent next dumping scheme and site management after the cloudy bay two typical section 1. 24, 1. 38 respectively, and the st ability coefficient of stability meet requirements. The results showed that the stability analysis and engineering practice after comprehensive consideration of soil presser foot scheme of creep slope governance was effective, for guiding the late row soil work and the same type mine dump slope stability control had a certain guiding sign ificance.
