摘要
采场结构参数优化对于矿山的安全高效开采具有十分重要的意义。为确定某铁矿山南矿段的采场结构参数,应用有限元数值模拟软件建立3种数值计算分析模型,并计算矿体开采充填过程中应力分布和位移变化情况。综合分析矿体开采过程中的应力和位移云图,得出采场结构参数的最优方案:采场长50m,高50m,宽25m。
Optimization of stope structure paremeters for safe and efficient mine production is of great significance. To determine the structure parameters of stope for the south ore block in an iron mine, three kinds of numerical analysis models were established, and the stress distribution and displacement changes were calculated in the process of ore excavating and filling by finite element numerical simulation software. The results showed that stope structure parameters with length of 50 m, height of 50 m, and width of 25 m were the optimal solution by comprehensive analysis of stress and displacement contours in the process of ore excavating.
