摘要
在分析造成采场溜井破坏的主要原因基础上 ,应用FLAC3D数值计算软件 ,从岩体应力分布、塑性破坏区和岩体移动等方面 ,系统研究了溜井加固前后的围岩力学状态 。
Based on the analysis of the main causes of stope chute failure,FLAC 3D numerical calculation software is used in the systematic study of the mechanical state of the surrounding rock before and after the chute reinforcement from the aspects of the stress distribution of rock mass,the plastic fractured region and the movement of rock mass so as to disclose the fracture mechanism of the surrounding rock and the mechanical system of the reinforcement engineering.
