Study and Practice on Rock Mass Cofferdam Blasting Demolition of Pumped Storage Power Station

摘要

Based on the analysis the difficulties and characteristics of rock mass cofferdam blasting demolition in pumped storage power station, study on some key technology problem such as the optimization of rock mass cofferdam shape and blasting scale control in rock mass cofferdam demolition, blasting particle control and the optimization of blasting parameters, blasting safety control standard and single dose control, blasting adverse effects and safety protection and so on, and with Bailian River pumped storage power station rock mass cofferdam blasting demolition as an example, the paper detailed introduces the practical application of this technology, provide reference for the similar projects.
