The Numerical Simulation Study of the Influence on Stability of Slope by Underground-mining under Opencast Coal Mine Slope

摘要

In the view of study on Mining transferred from open -pit to underground caused the research of the problem of the stability of slope is less. This article combines the actual situation of the Haizhou open -pit of FuXin city, and sets up the three - dimensional model of the part of Haizhou open — pit slope by the finite difference software software. Through the three -dimensional numerical simulation study of the influence on stability of slope by underground -mining won the basic characteristics of the open pit slope deformation and the situation of the basic stability. The simulation results of the mining slope of the displacement and deformation analysis of state for mining analysis provides a reference to the slope.
