Coordinates: 22°21′N 82°41′E / 22.35°N 82.68°E The 2009 Korba chimney collapse occurred in the town of Korba in the Indian state of Chhattisgarh on 23 September 2009. It was under construction under contract for the Bharat Aluminium Co Ltd (BALCO). Construction had reached 240 m (790 ft) when the chimney collapsed on top of more than 100 workers who had been taking shelter from a thunderstorm. At least 45 deaths were recorded.
Plans specify a 275-metre (902 ft) chimney for the construction of a thermal power plant by Balco, which is owned by Vedanta Resources. The incident happened during extreme weather conditions involving lightning and torrential rainfall. Workers sought shelter from the rain in a nearby store room, and a lightning strike at approximately 16:00 brought the chimney down on top of them.<
A rescue attempt was initiated following the collapse. Ongoing rain obstructed efforts to retrieve the trapped workers. At least seven of the wounded were hospitalised. An GDCL employee was allegedly lynched by angry workers; his corpse was located near the scene. It was originally thought he had fallen from the chimney, but wounds indicate he was attacked.
An investigation is ongoing to determine the cause of the collapse. Balco initially did not discuss the incident at length, stating only that "[t]here is an accident and some people are injured"; claiming to be too busy with the rescue effort to make a longer statement. The state government believes that Balco had been "overlooking security aspects". District superintendent of police, Ratanlal Dangi, described it as "a massive accident".Rs.100,000 (US$2084) in compensation will be granted to relatives of each of the dead.
