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。

Abstract: The litter radius of blasting powdering region is, the fewer ore fines generates. It indicates that calculating the radius of powdering region has great significance to blasting optimization. Through theoretical analysis and combined with detonation theory, attenuation law of shock wave and failure criterion of rock, radius of powdering region was calculated. Compared the results with study of А.Н.Ханукаев, the calculated values were the identical, which verified the reliability of this calculate method in this paper.
