摘要
研究散体移动密度和速度场是放矿理论的重要内容之一 ,本文基于随机介质放矿理论提出了膨胀散体移动密度函数和等密度体方程、移动速度函数 ,并对移动场进行了分析。
Researching the movement density field of granular mass is important in ore-drawing theory.On the basis of stochastic theory of ore-drawing the author puts forward the movement density function and the equal density body equation as well as the movement velocity functions of dilatant granular mass,and analyzes movement field in this paper.
