    Abstract
  • Based on parallel computation of explosive blasting in concrete and analysis of the numerical result as well as study on the foundational theory of explosion mechanics, a conclusion has been drawn that in the process of explosive blasting in rocks, explosive energy is released by way of shock waves several times reciprocate reflect in blast cavity which is full of explosion product while rock mediums are damaged and moved, and the interface loses gradually its positive expansion velocity along with the rarefaction wave in blast cavity.
