Vibration Measurement and Analysis on Control Blasting Technology for Shaft Excavation of the Reservoir Dam Area

PING Qi1,MA Qin-yong1,XU Xiao-he2 (1.School of Civil Engineering and Architecture,Anhui University of Science and Technology,Huainan 232001,China;2.Construction Comittee of Changshou,Chongqing 401220,China)  
In the light of its practical construction,the blasting parameters of the shaft were designed,and the monitoring method and results of shaft blasting excavation in the reservoir are introduced.From the typical waveform graph,different wave peaks are separated as the designed millisecond delay intervals.The blasting sections are reasonable because no peak overlapping was found due to sectional blasting.The maximum vibration speed is 2.68cm/s,therefore the blasting vibration has no impact on the dam.
