摘　　要：本文从崩落矿岩移动规律的角度 ,就无底柱分段崩落法结构参数对矿石回收指标的影响情况进行了分析和研究。研究表明 ,对于矿体条件较好的无底柱分段崩落法矿山 ,由于特殊的结构和连续的放矿空间 ,结构参数在一定范围内调整不会显著影响矿石的回收效果 ;无底柱分段崩落法的结构参数可以根据采矿技术及经济的需要在较大范围内进行调整。Based on study of caved ore and rock flowing law,this paper analyzes and studies the influence of sructural parameters of sublevel caving on ore recovering results.The research results show that ore recovering results may not be affected significantly by the change of structural parameters due to the special structure and the continuing flowing space for caved ore and rock if the change of structural parameters is in a reasonable range and the sublevel caving has a favorable ore body conditions.This means the structural parameters of sublevel caving can be adjusted within a considerable range according to the needs of mining technical and economical considerations.
