Research on slope stability of open pit mines under different load actions
To study the deformation law of slopes under external loads,a metal open-pit mine in the southeast region was taken as the research object.By analyzing the deformation of slopes under rainfall and blasting condi-tions,the stability of open-pit mine slopes under different loads was studied.The research results indicate that rainfall has a certain scouring effect on the slope,weakening the strength of the rock mass,and with the duration of rainfall,the deformation of the slope continues to increase.Blasting has a disturbance effect on slopes,and there is a growth phenomenon over time,with the impact becoming more pronounced as the blasting period approaches.Therefore,analyzing the deformation law of slopes under external loads and studying slope stability can have refer-ence significance for the safety of open-pit mine slopes.
