摘要
本文就影响镜铁山矿输出矿石块矿率因素进行了分析研究。研究表明，放矿过程中岩石混人对采出矿石的粒度组成有直接的影响。在镜铁山矿条件下，减少放矿过程中的岩石混人，是提高镜铁山矿输出矿石块矿率的重要途径之一。
In this paper,a factor infiuencing on ore lump output is analysed. It shows that the rock dilution during ore drawing directly influences on the size distribution of mined out ore. Under conditiorls ofJingtieshan Iron Mine, decreasing rock dilution during ore drawing is one of important ways for increasingore lump output.
