The stability of the dump in the large inclination area of ​​the open-pit mine is very important to the safe production of the mine. The pit blasting treatment of the basement can effectively improve the stability of the dump. This study analyzes the effect of the area ratio and dispersion degree of the treatment area in the puffed surface blasting method on the deformation and failure of the dumping bench in the large inclination area. Based on the limit equilibrium method, the relationship between the stability factor and the area ratio of the treatment area is deduced. How does the area ratio and dispersion degree of the treatment area affect the deformation and failure mechanism of the dumping site with inclined basement. The results show that the stability factor is a quadratic function of the area ratio of the treatment area. An increase in the ratio leads to a sharp reduction in deformation and a significant change in the direction of deformation. The increase in dispersion effectively reduces the displacement and shear strain increments, and the failure mode changes. . The research on pockmarked blasting in this paper provides a basis for the optimization of dumping in the large dip angle area of ​​open-pit mines.

The stability of the draining field in the large inclination area of the open-pit mine is very important for the safe production of the mine, and the substrate of the hemp blasting treatment can effectively improve the stability of the draining field. This study analyzes the effect of the processing area ratio and dispersion degree on the deformation and destruction of the drainage steps in the large inclination area in the hemp blasting method, deducts the relationship between the stability coefficient and the processing area area ratio based on the limit balancing method, and studies how the processing area ratio and dispersion degree affect the deformation destruction mechanism of the slope substrate drainage field through numerical simulation test. The results show that the stabilization coefficient is a secondary function of the area ratio of the processing area, which leads to a sharp decrease in deformation, a significant change in the direction of deformation, an increase in dispersion effectively reduces displacement, shear strain increment, and changes in destruction mode. In this paper, the study of hemp surface blasting provides a basis for the optimization of soil draination in the large inclination area of open-pit mines.

The stability of dump in large dip angle area of open-pit mine is very important for mine safety production, and the stability of dump can be effectively improved by pitted blasting. In this paper, the influence of the area ratio and dispersion degree of the treatment area on the deformation and failure of the dump bench in the large inclined area is analyzed. Based on the limit equilibrium method, the relationship between the stability coefficient and the area ratio of the treatment area is deduced. Through the numerical simulation test, the influence of the area ratio and dispersion degree of the treatment area on the deformation and failure mechanism of the dump in the inclined base is studied. The results show that the stability factor is a quadratic function of the area ratio of the treatment area. The increase of the ratio leads to the sharp decrease of deformation, the obvious change of deformation direction, the increase of dispersion degree, the effective reduction of displacement and shear strain increment, and the change of failure mode.
