(一)问题的提出在“关于崩落法放矿时矿岩移动方程”(以下简称文献[1])一文中,用divV=0对“放矿基本规律的统一数学方程”(以下简称文献[2])进行了连续流动检验,并得出了以下几点结论:1.文献[2]首先提出的幂函数的偏心率回归方程,即1-ε~2=KH~(-n),因为它形式简单,便于应用,同时也能较好地满足速度矢量的散度要求;2.文献[2]得出的速度方程,在Υ=0时,可以满足连续流动条件divV=0的要求;3.文献[2]得出的速度方程,在Υ(?)0时,不能满足连续流动要求,这一点正是文献[2]中存在的问题;
(1) Proposing the problem In the article “On the movement equation of ore and rock during caving of ore deposits” (hereinafter abbreviated as reference [1]), use divV=0 for the “Unified Mathematical Equation of Basic Rules for Ore Drawing” (hereinafter referred to as “[ 2]) The continuous flow test was conducted and the following conclusions were drawn: 1. The eccentricity regression equation of the power function first proposed in [2], namely 1-ε~2=KH~(-n), because It is simple in form, easy to apply, and can well satisfy the divergence requirement of velocity vector. 2. The velocity equation obtained in [2] can meet the requirement of continuous flow condition divV=0 when Υ=0. 3. The velocity equations derived from the literature [2] cannot meet the requirement of continuous flow when Υ(?) 0. This is exactly the problem in [2].
