采用FLAC对金山店铁矿 - 2 0 0m阶段西区回填体和采场围岩受力状况进行数值模拟 ,分析了其稳定性 ,为该矿确定矿床开采与采准巷道参数的选择提供了可靠的理论依据。该方案简单易行 ,在处理矿山类似问题时 ,与传统的受力分析方法相比 ,具有较大的优势。
The FLAC is used to simulate the stress condition of the backfill and the surrounding rock of the Jinshandi Iron Mine in the western part of the 200m stage, and the stability of the rock mass is analyzed, which provides a reliable basis for the determination of the ore deposit and the selection of the parameters of the roadway for the mine. Theoretical basis. The scheme is simple and easy. Compared with the traditional method of stress analysis, it has a great advantage when dealing with the similar problems in mines.
