Expecting the details would emerge in "a couple of days" on what actually transpired during the bidding process for these mines, Coal Secretary Anil Swarup insisted that the government wasn't looking at cartelisation aspect at the moment.
There have been reports that some bidders could have indulged in cartelisation to keep the prices low for the concerned mines.
"In the schedule II, we were looking at four mines and in schedule III we are looking at five mines...Prima facie we found that it requires a re-examination, so it has been re-examined that is about all," Swarup told news channel CNBC TV18.
The bids of four coal blocks of the schedule II mines (ready to produce) which are being re-examined are Gare Palma IV 2, Gare Palma IV 3, Gare Palma IV-1 and Marki Mangli III.

The coal blocks which do not figure in the list of successful bidders of schedule III mines are Brinda and Sasai mine (one bid was invited for both the mines), Meral mine, Dumri mine, Tara mine and Mandla South mine.
On whether the government has noticed any evidence of cartelisation, Swarup said: "As I said, this is a process underway. I would not like to comment on what is going on the file. A decision will be taken in couple of days and you will get to know what has happened."
"Whether it is a cartelisation or not it not something which I can say as of now. We are certainly not examining these aspects. We are examining if there is an outlier the reason for it and then we will take a call."
So far, a total of 33 coal blocks have been auctioned in two tranches. While in the first lot 19 coal mines were auctioned, in the second lot 14 coal blocks went under the hammer.
