早在五十年代初期,苏联学者就通过大量的实验,建立了椭球体放矿理论。我国的专家和工程师们对此理论的发展和完善也作出了自己的贡献。由于这种理论来自实验,简单明了,易于运用,它的部分观点已在理论上和生产实践中得到了验证,因此乞今为止,此理论仍居主导地位。但由于椭球体放矿理论的某些观点概念不清,前后矛盾,有的甚至是错误的,对一些基本规律,缺少必要的严格论证。例如“等速体”这个概念,从定义到推导以至于方程式的建立,都是不够完善的,甚至是有错误的;而放矿时矿岩颗粒运动轨迹方程也
As early as the early 1950s, Soviet scholars established large-scale experiments of ellipsoid ore drawing. Our experts and engineers also made their contribution to the development and improvement of this theory. Since this theory comes from experiments, is simple and straightforward, and easy to use, some of its ideas have been validated both in theory and in production practice, so this theory still dominates. However, due to the unclear concepts of certain views of the ellipsoid drawing-ore theory, inconsistencies before and after, and sometimes even mistakes, some basic laws are lacking in the necessary strict argument. For example, the concept of “constant velocity body” is not perfect or even wrong from the definition to the derivation and the establishment of the equation; and the equation of ore particle motion trajectory
