Multi-Factor Analysis on the Stability of High Slopes in Open-Pit Mines

During the production of open-pit mines, stability slopes can be affected by various factors such as structural surfaces, blasting vibrations, and mining areas. In this study, researchers focused on slope mine at Yinshan employed UAV mapping technology to conduct an on-site geological engineering investigation. Information yield, trace length, spacing, density surface south was obtained. The also carried out vibration tests in combination with activities determine attenuation law whether speed met safety specifications. Additionally, numerical simulation methods were used examine influence area current designed excavation slope. evaluated using limit equilibrium method, separately discussed self-weight load plus force high open pit. results showed following: (1) rock mass plane mainly dominated a medium-large dip plane, three faults joint fissures investigation combined form cutting sliding surfaces that prone collapse sliding. (2) maximum requirements. (3) There no large range plastic zone damage entire slope, overall good. (4) present relatively stable when considering only stress force. However, there certain risk instability design
