摘要
结合南芬铁矿 1号驱动站大硐室的工程地质条件 ,分析了该矿岩体条件下自稳结构的形成、特点、破坏机理、支护方式的关系。在现场监测数据和有限元数值计算的基础上对南芬
According to the engineering geological conditions of big underground opening of No 1 driving station in Nanfen Iron Mine,the formation,characteristics,failure mechanism of self sustaining structure and its relationship with supporting mode are presented.Then based on the results of in site monitoring and numerical simulation the formation of self sustaining structure in No 1 driving station and its stability are analyzed.
