Outline
On the basis of revealing the formation mechanism and development mechanism of the slope in the latent sliding zone of Shuguang Gold-Copper Mine, the treatment work of slope in the latent sliding zone was carried out. The formation factors and processes of the latent sliding zone were studied through on-site engineering geological investigation and limit equilibrium analysis. Based on engineering geological investigation, the formation factors of the latent sliding zone were divided into internal and external factors, and the formation process was divided into three stages, including the generation, development, and penetration of slope cracks. Combining the treatment conditions, a treatment scheme with large-diameter anti-slip piles has been formulated. Through engineering geological investigation and parameter back calculation, the rock mass parameters and the position of sliding surface of the latent sliding zone have been determined. Based on the residual sliding force calculation, a single row of circular anti-slip piles with a diameter of 800 mm, a length of 32 m, and a hole spacing of 4 m will be constructed on the 590 m platform. Three limit equilibrium analysis methods were used to verify the stability of the post-treatment slope, and the results show that anti-slip piles can effectively resist sliding. The research results can provide a reference for safety production and slope treatment in mines.
