摘　　要：针对上向分层充填采矿法生产作业中存在的问题,将真实物理模拟实验与虚拟数值模拟实验相整合,设计了实验工艺流程和装置,对全尾砂压缩固结充填技术进行实验研究。采用固结强度测试、平面物理模拟、三维数值模拟等方法,对不同载荷条件下充填体的力学特性,以及上向分层充填采矿过程中充填体、矿体、围岩的应力、应变的变化规律进行了实验研究。According to problems existing in upward cut-and-fill mining,the experiment model of integration of the physical simulation experiment and the numerical simulation experiment was formed and the experimental process and devices were designed. The experimental study on the relationship between loading and consolidation strength was carried out.Using the two-dimensional physical simulation method and the threedimensional numerical simulation method,the experiment went on,and the change rule of stress and strain of backfill,orebody and surrounding rock was obtained.
