摘要
引入岩体裂隙分布的统计理论，探讨了爆堆岩块的分形特性，从统计岩体力学及爆炸分形的角度建立爆炸过程并对硐室爆破进行级配分析，级配预测结果和实际工程吻合较好。
The fragment size distribution is the main problem of production of materials for rockfill dam by means of chamber blasting.In this paper, the author refers to the statistical distribution of cracks in rock body, and analysizes its fractal characteristics of the fragments. The prediction of fragment distribution for chamber blasting is deduced is this paper. The result is in agreemeat with that of the practice.
