AI Technical Summary

Technical Problem

Existing calculation methods cannot effectively account for the quantitative impact of irregular V-shaped slope morphology on stability in open-pit mines, leading to difficulties and complex calculations in three-dimensional stability analysis.

Method used

Based on the limit equilibrium theory and the spatial mechanical effects of slopes, a potential sliding body spatial morphology equation for a V-shaped slope is established. By dividing the slope into micro-columns and performing static equilibrium analysis, the equation is transformed into a two-dimensional equivalent shear strength parameter. The stability coefficient is then calculated using the rigid body limit equilibrium method.

Benefits of technology

It realizes a two-dimensional equivalent characterization of the three-dimensional stability of V-shaped slopes, simplifies the calculation process, reduces costs and the difficulty of parameter determination, provides more reliable theoretical and technical support, and ensures mining safety and production efficiency.
