Based on the current damage model studied by Kuszmaul, Thorne et al, a new model for rock fragmentation by blasting has been presented.applying fractal theory and its achievements used in rock mechanics. In the new model named FDM, the original damage in rock is determined by the fractal dimension of fracture or flaw in it which is the basis of rock fragmentation, and the damage evolution during blasting is connected with the fractal dimension and damage energy dissipation rate.

Based on the current damage model studied by Kuszmaul, Thorne et al, a new model for rock fragmentation by blasting has been presented.applying fractal theory and its achievements used in rock mechanics. In the new model named FDM, the original damage in rock is determined by the fractal dimension of fracture or flaw in it which is the basis of rock fragmentation, and the damage evolution during blasting is connected with the fractal dimension and damage energy dissipation rate. Thus two defects in current model have been remedied which the direct effect of original damage is disregarded and the damage evolution is reduced to the functionof bulk strain. The postulates of the new model have been verified by the results of simulated testand other methods.

在Kus和Thorne等人研究基础上,利用分形理论及应用成果提出了一种新的岩石爆破损伤模型。新模型将岩体中各种结构弱面视为初始损伤,并将其分形维数作为岩石性质的主要参量,用损伤能量耗散率及与分形维数的关系表征爆破过程中的岩石损伤演化规律,从而弥补了现有模型未考虑初始损伤影响和将损伤演化归结为体积应变函数的不足。还通过模拟试验等手段验证了新模型的如上观点。

Under the function of blasting loading,the rock damage evolution has an evident percolation effect. It is feasible to use percolation model to describe the process of the damage fracture of rock blasting. The potential further research approach is suggested.
