摘　　要：炸药爆破时,爆破粉碎圈半径越小,产生的粉矿越小。因此,计算粉碎圈半径对爆破优化具有实质性意义。结合爆轰理论、冲击波衰减规律、岩石破坏准则,通过理论分析计算出了粉碎圈半径,与哈努卡耶夫的研究对比,计算值与之基本相符,验证了计算方法的可靠性。cates that calc The litter radius of blasting powdering region is, the fewer ore fines generates. It indi- ulating the radius of powdering region has great significance to blasting optimization. Through theoretical analysis and combined ure criterion of rock, radius of powdering H.
