摘　　要：根据爆破块度预测模型存在的问题 ,结合一组爆破试验 ,分析了最小抵抗线、炮孔密集系数、炸药单耗等爆破参数对爆破块度效果的影响 ,得出了这些因素影响程度的关联序 ,为爆破参数的合理选择提供了借鉴。In order to overcome shortage of model for predicting size performance of block blasted,a new approach of gray correlation analysis of blasting parameters(such as burden of hole,concentration coefficient of holes,unit consumption of explosive)influencing size performance of block blasted is introduced based on a series of blasting tests.The correlation sequence of these blasting parameters is obtained that can be taken as reference for reasonable selection of blasting parameters.
