马拉霍夫在五十年代初期,写出《崩落矿块的放矿》建立了放矿椭球体理论体系。特别是在运用该理论说明矿石损失贫化过程以及确定崩落采矿法合理结构参数等方面进行了大量工作。迄今该书仍是崩落法放矿方面的一本较好的参考书。马拉霍夫放矿理论的基本点是:1.放出体是旋转椭球体,矿石放出时以椭球体形式移动;2.在移动带内存在表面垂直下降速度相同的等速体,其形状也是椭球体,并且在 In the early 1950s, Malahov wrote a “draining ore block” to establish a theoretical system of ore-laying ellipsoid. In particular, a great deal of work has been done in applying this theory to explain the process of ore loss and depletion and to determine the reasonable structural parameters of the caving mining method. So far the book is still a good reference book for ore caving. The basic points of the Maravhov ore draining theory are as follows: 1. The launching body is a spheroid which moves in the form of an ellipsoid when it is released. 2. There is an isokinetic body with the same vertical descending velocity in the moving belt, and the shape is also Ellipsoid, and at
