| Abstract: | The characteristics of the diversion tunnel on the eastern end of Jinping Hydropower Station are deep-buried sur- rounding rock and high geostresses and others. According to these characteristics, we can choose the appropriate technology of the tunnel blast. Through the analysis and calculation, we can decide the parameters of smooth blasting, the blast-hole arrangement and the distribution of the explosive etc, and propose a reasonable design program of the smooth blasting to instruct the tunnel construction and achieve good effect. |
