The national coal quality watchdog has downgraded 177 of Coal India Ltd’s 413 mines, potentially impairing the monopoly miner’s profitability, starting from the current year. The downgrades took effect 1 April. A total of 2,636 samples from the miner’s seven subsidiaries were examined and that led to the downgrading of 177 mines, said a key official at Coal Controller’s Organization (CCO), the watchdog.
