Developed with foreign technology for Rs.100 crore in 1986, the dragline 'Pruthvi Banjan' was deployed in Singareni’s first opencast coal mine, OCP-1, in the Ramagundam-III area. Over its 35-year lifespan, it worked for 1.7 lakh hours, significantly contributing to coal production by removing the overburden accumulated on coal stocks.
