| 摘 要： | 为了解决武钢集团金山店铁矿深部开采面临的高地应力问题，在分析深部矿床赋存特点及矿岩物理力学性质的基础上，提出4种开采顺序方案，并运用三维弹塑性有限元软件对4种开采顺序方案进行数值模拟，分析各方案开采后水平分段应力分布状态以及安全系数，结果表明由上而下由东向西的回采顺序有利于实现深部矿体安全高效的回采。

| Abstract: | In order to solve the high ground stress problem of deep mining faced by Jinshandian iron mine of Wusteel Group，and based on the analysis of occurrence characteristics of deep deposit and physical-mechanical properties of ores，4 kinds of mining sequence schemes were put forward，and the three-dimensional Elastoplastic FEM software was adopted to make numerical simulation on these four schemes.The sublevel stress distribution and safety factor for each scheme were analyzed，and the results showed that the downward and eastward mining sequence is conducive to realize the safe and highly efficient mining for deep ore body. |
