Optimization analysis on the presser foot tracing distance of internal dumping in open-pit mine based on 3DEC
DING Xin-pin
Abstract：In order to solve the problem of soft rock slope deformation and instability about Baorixile Open-pit Mine, GeoStudio geotechnical environment simulation calculation software and 3d discrete element software 3DEC are applied, to study the slope stability control function of internal dumping presser foot and the internal waste dump tracing distance optimization problem. The results show that the internal dumping presser foot method has obvious control effect to side slope stability, when the internal waste dump tracing distance is 40m, slope deformation can be effectively controlled and work can be normally succeeded. Scientificity and applicability of the research result are validated in actual production, which is worth widely using in mines with similar condition.
