Abstract

How to select scientific and reasonable mechanical parameters of rock mass is particularly important to evaluation of slope stability. Based on the collection of engineering geological data about a mine, and through detailed survey and analysis of the engineering geological conditions in the field, the Hoek-Brown strength criterion was used to estimate the rock mass strength parameters of this mine. Finally, a numerical simulation model for the open-pit mine slope was established; the finite difference method was employed for numerical calculation of the slope stability; the rule of changes in displacement field, plastic zone and shear strain was analyzed; the stability of open-pit mine slope was analyzed and evaluated. These provide a basis for design and safe production of the mine.
