摘要
Abstract
In order to study the spatial distribution pattern of rock layers and convex slope stability in Baiyinhua No.3 Open-pit Mine,first,the surface-underground 3D geological model of Baiyinhua No.3 mine was established based on drilling core data and UAV aerial photography,and the surface-underground 3D geological model is transformed into a 3D numerical slope model to study the deformation and stability of the convex slope of Baiyinhua No.3 Mine.The results show that the distribution of rock layers in the sursural-underground three-dimensional geological model of Baiyinhua No.3 Mine is in good agreement with the distribution of rock layers shown by the core,which could accurately reflect the spatial distribution of slope rock layers.The failure is mainly concentrated on the bottom of the slope,the top of the slope and the corner of the north slope of the convex slope,and the simulation results are consistent with the field deformation area.关键词
