摘　　要：针对崩落采矿法放矿实验中存在的问题,将真实物理模拟实验与虚拟数值仿真实验相整合,优化了实验方案,设计了实验工艺流程和装置。采用平面物理模拟实验、立体物理模拟实验、三维数值仿真实验等方法,对不同步距条件下的端部放矿中矿岩流动机理和贫化损失变化规律进行了实验研究。According to problems existing in the ore drawing experiment by using caving method,based on the granular dynamics theory,the experimental model of integration of the real physical simulation experiment and the virtual numerical simulation experiment was constructed.The experimental scheme was optimized,and the experimental process and devices were designed.The experimental study on the movement law of ore and waste rocks and the change rule of ore waste dilution were carried out,by using the two-dimensional physical simulation test,the three-dimensional physical simulation test and the three-dimensional numerical simulation,the experimental study on the source of mixed waste rocks of ore drawing under the overlaying rock and parameters optimization is carried out.
