Abstract：In order to master the slope deformation law of grand stand area in the east slope of Wucaiwan No.1 Open-pit Coal Mine,based on the geological section of the slope engineering,the numerical calculation model of the slope is established,and the displacement deformation law is analyzed by FLAC3D software.Combined with the displacement data of two monitoring points,the latent sliding mode and deformation characteristics of the slope are comprehensively analyzed.The results show that the failure mode of the slope is the bedding sliding failure mode along the coal seam floor.The local deformation area is formed at the dumping step and the original rock step,and the abandoned material resists the deformation of the original rock step.Displacement monitoring shows that the slope has an overall horizontal displacement trend to the free surface,and the discarded materials are in the stage of constant settlement.The deformation law of numerical simulation is consistent with the research results of monitoring deformation.
