Abstract
The paper, starting from a series of general considerations regarding the closure of a mine, makes an analysis, according to the available data, of the manner some of the mines in the Valea Jiului were closed. It is specified that the relatively short time since the closure of the first mine in the Valea Jiului (30 years) did not allow to highlight any mistakes / errors of closure, which would have significant repercussions on the surface land and, in general, on the environment. However, more or less serious problems have already been reported, which arose after the closure of some mines, problems that appear in the last part of this paper.
