Abstract: The blasting program, parameter selection, blasting network and security measures of the cutoff wall demolition project of downstream transverse earthrock cofferdam in the secondstage project in Xiangjiaba Hydropower Station are introduced. The quality and safety control difficulty of flyrock from cutoff wall blasting was increased on account of the excavation of rockfill materials upstream. We ensured the quality and safety of the blasting construction by means of the strict implementation of the blasting program.

Key words: hydropower station, cofferdam, cutoff wall, demolition blasting
