现有的研究成果主要为水平、近水平、缓斜基底排土场变形破坏模式及防治措施

The existing research results mainly include the deformation failure mode and prevention measures of horizontal, nearly horizontal, and gently inclined basement dumping sites. There are few studies on large-dip basement dumping. The <br>literature[] solves the blasting parameters of pockmarked blasting from the perspective of blasting. , Did not analyze the deformation and failure mechanism of the <br>dump site after pit blasting from the perspective of stability. Combining the engineering background of the Luzigou anticline dumping in Anjialing Open-pit Mine , this paper first studied the relationship between the base treatment area ratio and the stability coefficient, and then The effects of processing different areas on the stability of dumps are calculated, and the deformation laws and failure mechanisms of dumps with large inclination angle basement are studied based on actual field and numerical simulation.

The existing research results are mainly horizontal, near-level, slow-slope substrate deformation destruction mode and prevention measures, for the large inclination base drainage less research,<br>The paper solves the blasting parameters of hemp blasting from the angle of blasting, and does not analyze the deformation and destruction mechanism of the soil field after hemp blasting from the angle of stability.<br>In this paper, combined with the engineering background of the back oblique drainage of the reed ditch of The Anjialing open-pit mine, the relationship between the substrate treatment area ratio and the stability coefficient is studied first, and then the effect of dealing with different areas on the stability of the drainage field is calculated, and the deformation law and destruction coefficient of the large inclination base drainage field are studied based on the actual and numerical simulation of the site.

The existing research results are mainly horizontal, near horizontal and gently inclined base dump deformation and failure mode and prevention measures, but there is little research on large angle base dump,<br>The reference [1] solved the blasting parameters of pockmarked blasting from the perspective of blasting, but did not analyze the deformation and failure mechanism of soil field after pitting blasting from the perspective of stability,<br>Based on the engineering background of luzigou anticline dump in Anjialing Open-pit Mine, the relationship between the ratio of base treatment area and stability coefficient is studied, and then the influence of different treatment areas on the stability of waste dump is calculated.
