本文用随机介质理论研究大量崩矿中的重力放矿规律问题。文中指出放矿场的移动区域周界是一非线性闭合曲线绕其对称轴旋转而成的闭曲面,表明该非线性闭合曲线在一般情况下不是椭圆,在一定条件下它近似瘦长的椭圆。并证明该曲线方程为 由此导出了放矿松动体(高H)的体积V_o、放出体(高h_d)的体积V_d分别为: 从而应用上述结果解释了重力放矿中的一些有关因素,对传统的经验“放矿椭圆”说提出了改进。
In this paper, we study the law of gravimetric ore draining in a large number of collapse with random medium theory. It is pointed out that the perimeter of the moving area of the mine is a closed curved surface formed by the rotation of a nonlinear closed curve about its axis of symmetry. This indicates that the closed nonlinear curve is not an ellipse under normal conditions, but it approximates an elongated oval under certain conditions. It is proved that the curve equation leads to the volume V_o of the releasing loose body (high H) and the volume V_d of the discharging body (high h_d), respectively. Therefore, the above results are used to explain some relevant factors in gravity ore drawing. The traditional experience of “Ore drawer” said that improvements were made.
