Gone in 15 seconds! Two 20-storey tower blocks are blasted to rubble in a controlled explosion after ‘being built illegally and left empty for nine years‘ in China


Two illegal tower blocks in were yesterday demolished in an impressive controlled explosion involving 1.1 tonnes of dynamites. 

The high-rises, both unfinished and 20 storeys, were blown into smithereens within 15 seconds in a city centre after being left untouched for nine years, according to a local newspaper.

There are numerous illegal buildings like these in China, a phenomenon that has caused much headache to authorities in the rapidly urbanised country.

Quickly disappearing: The two buildings in the city of Zhengzhou, Henan Province, were deemed illegal by the authorities

Structures can be deemed unlawful by Chinese authorities when the developers erect them on plots without planning permission or breaking rules during the construction process. 

The controlled explosion took place yesterday afternoon near a busy junction in the city of Zhengzhou, central China‘s Henan Province. 

The two towers, eight metres apart from each other, had been built by residents of the Changzhai Village through raised funds, reported local .

Soon after, authorities ordered the project to be halted, but the report did not explain why the structures were deemed illegal. 

Zhengzhou city planners said on Wednesday that the buildings had been earmarked for demolition to make room for a new project initiated by the government. 

‘This explosion has used the largest quantity of dynamites in the residential projects in Zhengzhou. [The amount] was seven times more than what we had used to blow up rocks,‘ Fang Guifu, chief engineer of the demolition project, told Dahe.

Before the explosion, workers drilled 7,263 holes on the structures before embedding 1.176 tonnes of dynamites, 9,160 detonators and 3,500 metres (2.1 miles) of detonating fuses. They also dug ditches around the site in a bid to reduce the impact to nearby buildings.

The two towers were brought down one after another in rapid succession.  

Mist cannons were at the scene to reduce air pollution.

Carrying a huge water at the back, those dust-control machines are often used in fighting smog in China. 

Yesterday, a fleet of eight of them blasted mist into the air to disperse the dust over busy streets right after the explosion.

The Zhengzhou government is planning to build a high-end residential complex, luxurious hotels and huge shopping malls in the area.
