Research on East No.1 Dump Slope Deformation and Failure Mode of Weijiamao Open Pit Mine

摘要

According to Weijiamao mine's specia geological and physical and mechanical characteristics,using FLAC3D numerical simulation software to simulate east No.1 mine deformation failure mechanism.And a detailed analysis of the displacement characteristics of the mine slope,the stress distribution characteristics and the damage characteristics of rock mass.The failure modes mainly occur in the abandoned materials inside the arc landslides and landslides along the foundation surface of foundation type,including a certain amount of settlement deformation.
