| Abstract: | A chamber blasting in excavation of Yuan-tai expressway in Shanxi province is introduced,in which the chamber blasting is implemented,and a few cracks and ruptures are found. To obtain an ideal result of blasting, factors such as the location of chambers, charge, stem and the proper delay times are calculated. The project are also analyzed. |
