中文摘要：

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。

英文摘要：

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 developed based on the void filling method.Different structural parameters are taken in the simulation experiment.The results 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.
