Abstract


Waste disposal is one of the most important part in the opencast mining. The Continuity of Stripping and Mining Projects are affected by the work. Dump go with landslide phenomenon under some conditions. In the practical work, stripe stability draws attention in recent years. In this paper, a number of studies on the YuanBaoShan 3# line ChangSheng dump are did from on-site survey, theoretical analysis and numerical analysis.In this paper,it summarizes Waste disposal slope failure mode about loess basement dump.In this paper, it determinate that the YuanBaoShan 3# line dump landslide model is a type of stant slip and reveals the landslide mechanism; Limit row abandon height of YuanBaoShan 3# line dump is calculated by the ultimate bearing capacity in the correction of the Prandtal which calculate the ultimate bearing capacity of soil overall shear failure;The stripe stability of YuanBaoShan 3# line is analysised by limit equilibrium method to rigid block and FLAC3D as numberic analysis.This paper puts forward the measures for preventing and controling about the drain of slope base and press stand.
