Stability simulation calculation of a large mine dump based on Midas
A waste dump is a place where mining waste is concentrated and discharged,and it is a giant artificial loose cushion.If the slope of the waste dump is unstable,it will lead to disasters and major engineering accidents in the mine,affect the normal production of the mine,and cause huge economic losses to the mine.This article takes the slope of a large mining waste dump as an example,and based on a systematic analysis of its engineering geological conditions,conducts grading,zon-ing evaluation,simulation calculation,and other work.The research results indicate that the slope level of the waste dump is Level 1,and it is divided into four areas,with Zone A having the highest slope height and the most serious potential hazards.Using Midas software,the stability coefficients of three typical profiles were calculated,among which the A-A'profile stabili-ty coefficient was 1.401,the B-B'profile stability coefficient was 1.385,and the C-C'profile stability coefficient was 1.404,all in a stable state.However,it is necessary to strengthen local deformation monitoring and stability analysis under extreme geological conditions.
