A massive power outage on Tuesday across India's north and east trapped more than 700 miners in underground coal mines.
India has a long history of energy problems and is one of the main importers of Australia's thermal coal.
Earlier this week the state provider of power went down, trapping approximately 700 coal miners that were at the time working underground in around 20 mines, half of which were known to be highly gassy, according to the Hindu Times.
The Asian Age reported that as soon as news of the incident was released families of the trapped miners began pushing for an immediate rescue.
A major crisis managed to be averted as one company, DPSC Limited, was able to supply enough power to keep some operations running and to rescue some workers, after one of the larger miners ECL sent an emergency distress call to the power provider.
Miners were not rescued until later in the day, with help from technical experts.
