Study on the Method for Slope Stability Analysis in Open-pit Mining and Its Preventive Measures

Research on the safety and stability of slope in open-pit mining is very significant to safety production of open mines. Based on the analysis of these factors affecting the slide of slope, this paper made a study and summary of the situation that methods for slope stability analysis were applied in open-pit mining. Three methods, often used in the safety assessment of slope in open-pit mining, were systematically explored. A typical example has been used to illustrate the applicability of the three methods. Finally, preventive and controlling measures were discussed and presented based on the analysis of mechanism of slope sliding.
