1. Introduction In order to study rock damage and fragmentation during blasting, many numerical models have been developed. These efforts have varied from semi-empirical [1,2] to formulations based on shock wave physics [3,4]. Numerical modeling of blasting has been focusing on the complexity of the blasting process. This complexity requires that numerical models be developed in a highly systematic fashion in close coordination with controlled field and laboratory experimentation. This work d…  相似文献
