Nineteen buildings in Wuhan's downtown area were demolished by five tons of explosives in only 10 seconds on Saturday, in order to build a new business district in the capital of central China's Hubei Province.
The blast area was located in the city's downtown area which lies next to a light rail viaduct, residential communities, a shopping mall and a transformer substation.
"For this kind of large-scale blasting demolition conducted in the downtown area, we not only need to guarantee the demolition result, but also strictly control the adverse effects of blasting," said Jia Yongsheng, general director of the project
Jia said his team erected more than 120,000 protective screens and prepared five tons of explosives. In order to guarantee safety, they set the collapse time to the millisecond.
"The demolition effect was ideal. The explosion didn’t affect the light rail and public facilities around the blasted buildings. There was no damage or adverse effects of blasting," said Jia.
