In May, a ministerial panel had recommended conditional forest clearances for developing these two coal mines.
The Group of Ministers had given green signal for Chhatrasal and Mahan coal blocks after accepting recommendations of an expert panel set up by the Environment Ministry.
The sources said that all basic formalities related to the clearances have been completed and the files are with Environment Minister Jayanthi Natarajan.
She is expected to clear the projects soon, they said.
Anil Ambani group firm Reliance Power was alloted Chhatrasal mine for its 4,000-MW ultra-mega power project at Sasan. The Mahan coal block was jointly allocated to Essar and Hindalco for a power project.
Greenpeace, a green NGO had alleged last week that the Environment Ministry has given its nod to divert the Mahan forest area in Madhya Pradesh for a coal block.
The NGO, which has been campaigning against diversion of forests lands for coalblocks in the country, had termed as "appalling" the Environment Ministry's move to give clearance to Mahan coal block.
Greenpeace India campaigner Priya Pillai had said that the clearance is in violation of the Forest Rights Act and is a threat to the livelihood of more than 14,000 people dependent on Mahan forests.
