| Abstract: | The excavating sequence in a large scale chamber blasting is introduced . The implementation method of controlling the chamber excavation by quasi presplit blasting technology is described.In accordance with the disadvantages of the traditional presplit blasting, the quasi presplit blasting which enlarges the hole space was used to achieve the effectiveness that can not be achieved with smooth blasting, and to improve the economic benefits and implementation process. |
