Three-Dimensional Simulation Stability Analysis of Slopes from Underground to Open-Pit Mining

The stability of mine slopes is an important factor influencing the orderly production mines and safety people’s lives property. can be effectively determined by means three-dimensional simulation analysis. Some 3D analysis methods are based on 2D analysis, still essentially methods, whereas this digital uses a true method. This method reflect overall slope in more realistic way, at same time, situation selected sections observed, making scientific rigorous. study takes Shizhuyuan Nonferrous Metal Mine as example studies through results show that open-pit stable. model there only small amount tensile damage no penetration; section absolute value stress generally small, with maximum 1.45 MPa being less than strength material (7.04 MPa). After monitoring simulation, it found displacements each point process fluctuation then stabilisation, which also indicate finally stable state. Comparing above conclusions obtained from method, to general agreement, indicating effective feasible.
