| Abstract: | The partial stability and integral stability of the high sideslope of Zhuziba quarry are analyzed for drawing up its permanent protective scheme.The unfavorable fissures composition and probable instable mode of the high sideslope are assessed by means of stereographic projection.The stability factors of the high sideslope under different excavating conditions are calculated by means of rigid body limit equilibrium.The relevant reinforcing measures are suggested. |
