The one-day strike on Tuesday by coal workers against FDI in the sector has led to an estimated loss of 1 million tonnes (mt) in production as the Centre looks to initiate talks with the unions to normalise the situation by Wednesday.
The strike has affected production across the subsidiaries of Coal India and Singareni Collieries.
The unions said the strike was successful even as coal minister Pralhad Joshi hoped that production would normalise from Wednesday.
Coal India, which produces over 80 per cent of the production of the mineral in the country, saw its attendance go down in the early shifts, with only officers present.
