Two 105-meter-high steel boiler plants and two 105-meter-high cooling towers fell in seconds in Taiyuan, Shanxi Province on Nov. 20.
The controlled explosion was impressive.
It is said to have been the most difficult demolition to date, the project manager said.
With innovative scheming, the project only needed 280 kilos of explosives.
Conventional means would have require over 1 ton.
