The Study on Blasting Shock Control for A Hydropower Plant under Operation

This paper gives priority to the study of impact of blasting shock on the power generating units and their instruments of a power plant under operation and makes an approach to the safety assessment basis and control standard of blasting shock according to the experiences gained from realignment and widening of the river bed downstream from the Gongzui Hydropower Plant on the Daduhe River. The paper also has made comparison and analysis using the experiences and indexes obtained from a number of similar practical projects. The conclusions drawn from the study could be used for reference in terms of safety control of blasting shock for other projects of this kind.
