| Abstract: | The project of directional controlled demolition blasting of 210m high reinforced concrete chimney is introduced.Some methods were,such as emphatically introduced,the pretreatment measures,shape and size of blasting cut,blasting parameters,blasting network based on digital electronic detonator,safety technical measures and blasting effect.Especially the electronic digital detonator was the first time in high amounts to high structure demolition blasting.The digital electronic detonator applied good resistance to stray electrical effect,ensured the blasting work in the power plant security implementation,which improved the accuracy of extension.Can be used for reference for the similar projects. |
