三山岛金矿盘区回采规格数值模拟优化

Numerical Simulation Optimization of Panel Stoping Specification in Sanshandao Gold Mine

三山岛金矿S12186采场为盘区法试验采场,在采场宽度确定的情况下,合理布置矿房宽度成为安全生产的重要因素。通过采用FLAC3D软件,对5种不同矿房布置形式进行数值模拟,分析了不同方案应力、位移和塑性区的分布情况,提出了最优的回采规格,为安全回采提供了理论参考。

Taken the S12186 slope of Sanshandao Gold Mine as the panel method test slope, with a certain width of the slope, the reasonable width of the chamber was a critical factor which affects the safe- ty production. Numerical simulation was done on five different specification of the chamber using FLAC3 D, stress distribution, displacement distribution and plastic zone distribution of different plan were analyzed. The optimal specification of stoping is proposed, which provides some reference for safe stoping.
