State-run behemoth Coal India Ltd (CIL) produced 323.57 million tonnes (MT) of coal in the first eight months of the current financial year.
The world's largest coal miner had set a target of 360.84 MT during the April-November period of 2016-17 financial year, it said in a regulatory filing.
During November, the miner produced 50 MT of the fossil fuel against a target of 53.85 MT.
The offtake of the dry fuel by the coal PSU during the period was 340.32 MT, lower than the target of 381.55 MT.
Last month's offtake stood at 48.16 MT against a target of 49.80 MT.
CIL, which accounts for over 80 per cent of the domestic coal production, is eyeing 598 MT production in 2016-17 and targets to produce a billion tonnes by 2020.
