A 27 year old chimney at the Tata Steel factory in Jamshedpur Jharkhand was demolished on Sunday. The chimney – 110 meters high – was safely demolished in just 11 seconds and the company tweeted a video of the process, underscoring that it had been carried out in a safe, controlled and environmentally friendly manner.
The video shows an explosion at the base of a chimney after which it falls slowly and neatly into a designated area. This was followed by the use of ‘water curtains’ to control dust and ‘moats with dikes’ also used to absorb vibrations.
The use of ‘steel wrap’ ensures that debris is not scattered.
Tata Steel vice president, Avneesh Gupta, said: “The Jamshedpur factory’s 27-year-old 27-year-old battery chimney was demolished using the explosive method, which made the demolition process safe for the workers. It also saves time and is also environmentally friendly. The smoke tower was destroyed within 11 seconds.”
The demolition task was carried out by Edifice Engineering India in South Africa – the same company that reduced Noida’s twin towers to ashes. The towers, Apex (32 floors) and Ceyane (29 floors), were demolished with explosives weighing at least 3,700 kg, in the largest-ever tower demolition plan ever planned on 28 August.
Gupta further said the demolition was successful and did not cause any casualties. “Prior to the fall of this chimney, a 75-year-old man, a 2 meter high coke factory workshop was dismantled for drills,” he added.
