Abstract: Compared with traditional demolition technology, shaped charge cutting blasting technology has the characteristics of concentrated energy, rapid action, strong directivity, strong penetration, safe and easy construction, low requirements for working environment, and et al. Also, precise demolition of a specific object can be realized by use of it. By application of shaped charge cutting blasting technology to a hydropower station, the flood discharge gate was successfully demolished and the emergency rescue was successfully finished. The principle of shaped charge cutting blasting, the case design and its application prospect are briefly introduced in this paper, providing reference for safe and rapid demolition of large-scale structures in emergency rescue at hydropower stations, earthquake relief and situations under special environment conditions.

Key words: shaped charge cutting blasting technology, demolition, emergency rescue
