A simple search for "Adani mine" would give you all the info you need if you bothered, but start off with this
Actually I had already carried out more research than you care to name some time ago.
There are lots of "IFS and BUTS" about this project and its viability on todays market price of $60 per tonne and financial backers have moved away for this reason but Adani does have other resources from India.
I believe Adani may hang out until 2019 when coal prices are expected to increase to $88 per tonne....I think their break even point is around $54 per tonne.
