NEW DELHI (AP) -- Around half a million coal workers in India have vowed to continue their strike after inconclusive talks with the government, possibly jeopardizing power supplies.
Wednesday was the second day of a five-day strike called by five coal industry trade unions.
The unions have called the strike to protest the government's plan to open up the coal industry to private companies.
Supplies to nearly 100 coal-fired power plants have been hit, raising fears that it could lead to widespread disruption in power supplies.
Talks between union leaders and government officials remained inconclusive.
Prime Minister Narendra Modi wants to open India's mostly state-run coal mines to private players as part of wide-ranging reforms to boost the economy.
The five unions represent 3.5 million workers but a majority have not joined the strike.
