Provisional figures for the April-December 2017 period showed it has produced 383.93 million tonnes of the fossil fuel, falling short of the 406.58 MT target by six per cent.
However, during the nine-month period, it clocked a 1.6 per cent growth in production from 377.77 MT produced in the same period last year.
A CIL official said the company is striving to make up the shortfall by producing in excess of 2 MT per day.
With better availability of rail rakes and upstick in demand, the miner achieved a 7.6 per cent growth in off-take to 421.41 MT during the first nine months of the current fiscal, as compared to 391.78 MT during the same period last year.
Brokerage firm IIFL said in a report that there is a strong possibility that CIL would miss its annual production target.
CIL was given a production target of 600 million tonnes for FY'18, an annual growth of 8.3 per cent over FY'17.
