Abstract: Geological investigations on a rock slope near Boquan Iron Mine are presented in this paper. The investigations are performed on the rock slopes at the west side of the Pulverization Plant, south side of the Preliminary Broken Plant and Slopes from the Sieving Plant to the east side of the Preliminary Broken Plant. The stability of these slopes is evaluated and analyzed. The rock and soil parameters are determined from the laboratory testing on the samples from the rock slopes and the tailing mine.  The stability evaluation is also examined by using the FLAC3D finite element method. The mitigation methods are proposed for the potential problematic cutting slopes and rock falling areas.

Key words: Rock Slopes, Stereographic Projection of Rock Joints, FLAC 3D, Rock Mass Stability
