Blasting Demolition Technology and Vibration Testing of 210 m Reinforced Concrete Chimney
This paper describes the successful experience of the directional control blasting of 210-m-high reinforced concrete chimney of Nanchang Power Plant in Jiangxi Province called as “First height in Asia”. It emphatically describes the pretreatment measures, blasting cut shape and size, blasting parameters, electronic digital detonator detonating network and blasting safety technology. And the blasting vibration was tested and analyzed, and this paper presents the method for opening the arch overlarge oriented window and comprehensive protection method for anti-flyrock splash, vibration reduction and dustfall. Especially, the electronic digital detonator was first applied in the blasting demolition of 210-m-high structures, it improves the delay precision and also has a good anti-stray current effect to ensure that the blasting can be safely implemented in the power plant, and it has a good application prospect in the future large-scale and high level complex engineering blasting.
