| Abstract: | In this project, over 400kg weight lump rock occupied 30% of the total blasted rock volume. For purpose of sea filling and dyke building, the chamber controlled blasting is used in this project. In this blasting technology, single layer charge arrangement, the largest charge divided into two charges, Nonel millisecond delay controlled initiating methods are used. Excellent blasting results have been obtained. |
