摘　　要：影响爆破效果的因素很多 ,灰色关联分析能确定出影响爆破效果的各因素的主次关系。本文采用灰色关联分析方法 ,确定出会东铅锌矿影响爆破块度的主要因素为岩石爆破性指数 ,同时指出 ,在爆破设计中 ,调整炸药单耗和孔网参数 ,对控制爆破块度仍有重要作用。Blasting results are influenced by lots of factors,grey correlation analysis can determine the primary or secondary relationship of each factor which will affect the results of blasting.This paper verified with grey correlation analysis method that the blastability index of rock is the main fac tor affecting the blasting fragmentation of Huidong Lead-Zinc Mine and also demo nstrated that the adjustment of explosive factor and pattern parameters in blast design is still very important to the control of blasting fragmentation.
