| Abstract: | The important problems such as the scheme of the controlled blasting, deep-hole bench blasting, smooth blasting with lateral protecting layer and the excavation of the horizontally protecting layer of rock foundation of the permanent lock of Three Gorges Project are discussed in this paper. The practice could be used as reference for similar project. |
