The uranium ore extraction from Jaduguda and Bhatin mines, operated by the Uranium Corporation of India (UCIL), a PSU under the Department of Atomic Energy (DAE), has been suspended since September this year.
"The temporary shut down of the two mines led to a loss of production of additional mined uranium equivalent to about 19.1 tonnes, having the potential to produce about 860 million (86 crore) units of electricity," the official said.
Jaduguda mine, one of the deepest underground mines in the country, had run uninterrupted since 1968. It has a depth of nearly 3000 feet and had been daily producing 700 tonnes of ore. UCIL was mining 150 tonnes of ore from Bhatin daily.
DAE sources said it has taken steps to increase the production from other mines to maintain the supply and demand, but the low quality of ore from other mines has led to increase in the production cost.
