Blast Design and Optimization Studies Based on Vibration Control for Excavation of Hydropower Stations

It makes a systematic summarization on the key points of controlling blasting vibration for hydro-electric projects, including requirements of controlling vibration and prediction of vibration. Then it provides a set of blast design and optimization method on the basis of controlling blasting vibration. At last a case of blasting design by this method is introduced, which is from the project of Zhexi hydropower station. Results show that ground vibration is controlled effectively by this design method.
