摘　　要：本文通过对崩落矿块的随机模拟放矿和物理模拟放矿说明,侧面岩石混入量与放矿制度有关,并从数量上给出了这种关系。指出了那种认为放出体的形状与放矿制度无关,从而认为侧面岩石混入量与放矿制度无关的观点是错误的,根据那种观点预测出的侧面岩石混入量同样也是错误的。此外,文中还指出了降低侧面岩石混入量的途径。By means of both random and physical simulation of ore drawing, this paper expounds that the mixing volume of flank caved rock is concerned with the ore drawing system, and gives the quantitative relationship as well. It is considered a mistake that the shape of drawn body and the mixing volume of flank caved rock have no concern with the ore drawing system. And the mixing volume of flank caved rock deduced from this viewpoint is mistaken also. In addition, the way that reduces mixing volume of flank caved ...
