摘　　要：为推动放矿理论的发展和建立比较完善的放矿理论体系 ,对随机介质放矿理论中速度方程进行了评价 ,并补充了加速度方程 .指出随机介质放矿理论本质上仍然属于连续介质放矿理论 ,因此其速度、加速度方程必须满足连续介质放矿理论速度和加速度方程的要求 .研究结果表明 ,随机介质放矿理论的速度方程、加速度方程不能充分满足要求 。The velocity equations in the drawing theory in random medium were discussed in order to promote the development of the drawing theory and establish a perfect drawing theory system. And its acceleration equations were added. It was pointed out that the drawing theory studies the movement laws of broken ore and rock by means of the probability theory and has founded velocity equations which can reflect the movement features of loosing bodies, and has presented approximately the equation of movement boundary. It was demonstrated that this drawing theory is still a drawing theory in continuum and must meet the conditions of velocity and acceleration equations in the drawing theory in continuum. The research result shows that the velocity and acceleration equations in the drawing theory in random medium can not fully meet the requirement. Therefore, it was believed that the drawing theory in random medium is imperfect.
