Abstract：Based on the investigation，test and numerical analysis of the mine dumps，it is believed that the key of disaccord between results from the 2D-LEM and reality is system spatial effect under the interaction of base and dump body. The spatial clamp effect of convex and divergent effect of concave are explained，as well as essential relationship between height and radius of curvature which should be abided by 2D or 3D stability analysis is given on the basis of field test，theoretical analysis and physical model. Furthermore，the safe class，evaluation criterion and technical route which takes the factor of stability as major and also considers stress，displacement fields and plastic region distribution is established，under the principle that the deformation and partial failure are allowable.
