基于随机理论，结合力学判据，提出散体流动空位填充法，并给出模型建立规则和方法，简化散体之间的力学关系，为崩落矿岩流动规律的研究提供新的方法；同时基于空位填充法，研发了二维放矿仿真系统（ VFMS），并利用该系统对不同结构参数进行放矿仿真试验，得出的结果符合放矿规律，说明利用空位填充法模拟散体流动是可行的。
A granular flow void-filling method is proposed based on the stochastic theory and mechanical criteria . Modeling methods and regularities were presented so as to simplify mechanical relations between granular media and to provide new methods for the study of flowing rules of caved ores .A 2-D ore draw simulation system ( VFMS) is devel-oped based on the void filling method .Different structural parameters are taken in the simulation experiment .The re-sults are in consistence with that obtained by theory of ore-drawing .It means that the void filling method can be used in granular flow simulation .
