Research on monitoring and deformation failure mechanism of northern slope in Xianfeng Open-pit Coal Mine
摘要
Abstract
In order to study the deformation and failure mechanism of the northern slope in Xianfeng Open-pit Coal Mine,based on the field survey results,GNSS surface displacement monitoring,deep displacement monitoring and rainfall monitoring data,combined with FLAC3D numerical simulation,this article studies the deformation evolution process and failure mode of the northern slope.The results show that the northern slope is affected by rainfall,and the catastrophic evolution process is slow deformation,accelerated deformation,instability and failure;the shear sliding failure of slope soil occurs along the mudstone interbedding,and two shear sliding planes are formed in the middle and bottom of the slope;the numerical simulation results are consistent with the slope monitoring results.关键词
