Did the last high chimney in the main city of Ningbo be successfully blasted?

At 12: 47 on January 3th, with a loud noise, the last big chimney in the downtown area of Ningbo collapsed in the blasting, which lasted only five seconds, was submerged in flying dust and finally flattened. The towering blue-gray chimney is a reinforced concrete structure. The red brand "Changfeng Thermal Power 1997" on the chimney is still faintly visible from a distance. In 1997, it rose from the ground, but now there is no white smoke. The old chimney and the Ningbo Changfeng Thermal Power Group Co., Ltd. are adjacent to Fenghua River, located at Guangdehu Road at the foot of Changfeng Bridge. This is the junction of Haishu and Yinzhou, and it is also the Sanjiang area of Ningbo. The thermal power plant was completely demolished at the end of last year. Except for the chimney, only a wall near Guangde Hubei Road remained in the whole plant.

"Two days ago, I saw the public notice that the road was to be temporarily closed, so I guessed that the chimney was going to be demolished." "It has been said for 9 years that it has to be demolished, and this time it has finally been demolished." "Goodbye, old chimney!" ..... At 1 o'clock on the morning of January 29th, the last day left before the on-site blasting, reporters also met some citizens at the scene to "see me off". Approaching the old factory, a notice about blasting matters was posted on the glass window of the doorman, and Mr. Jin, the on-site person in charge of the blasting general contractor "Su Hua Construction Group", was just there. Mr. Jin said that the safety scope of this blasting is 18 meters away from the radius around the chimney, and the demolition unit in the early stage has been doing the final cleaning and preparation work in the same place to ensure that nothing is lost when blasting.
