自20世纪60年代无底柱分段崩落采矿法引进以来 ,已得到广泛应用.与其它采矿方法相比 ,该法具有机械化程度高、安全性好及采矿成本低等特点.但是 ,受松散覆岩下放矿条件的影响 ,其矿石损失贫化率较高 ,在开采过程中造成了大量矿产资源的浪费.本文通过对崩落矿岩的流动特性及移动规律的研究 ,进一步探索了无贫化放矿机理 ,为该法能在实际中更好的应用 ,提供了一定的理论基础.

The bottomless pillar sublevel caving method has been widely used in metal mines since it was in-troduced in the 1960 .Compared with other mining methods , this method unique to the high degree of mechanization , safety , and low cost of mining .However , it affected by the loose overburden rock under mining conditions , the ore loss and dilution rate is high , resulting in a large waste of mineral resources in the mining process .we can provides certain reference value for the actual production using the method base on the non dilution ore drawing theory ,which study on the flow characteristics and the movement law of caved ore and rock .
