The National Union of Mineworkers has urged UK Coal to request state aid so Thoresby Colliery can remain open until 2018.
The firm announced last week it had received a £4 million Government loan to finance the closure of the pit by July next year.
Representatives from the company met with the union on Monday night.
A spokesman from UK Coal refused to comment.
Chris Kitchen, from the union, said the talks were positive.
He said: "We have suggested they put in two applications for state aid - one to keep the mine open and another for a better redundancy package when it does close."
