Underground mines from Jiu Valley have as objective the extraction of hard coal, used for energetic purposes. Exploitation activities are associated with the extraction of significant amounts of sterile, derived from opening and preparing works, but also from coal processing activity. The sterile rocks are stored in waste dumps of different sizes, which must undergo periodic stability analysis. This paper aims to estimate waste dumps stability, by using fuzzy theory, the results of such an analysis being of qualitative type, which shows waste dumps technical conditions at a time and the need for detailed stability studies. Using this type of instrument allows early observation of variations of the waste dump stability reserve depending on the values of the considered variables, and intervention in the direction of increasing the stability reserve in order to ensure optimal conditions during the construction of the dump and in the process of ecological reconstruction. Moreover, estimating stability at a certain point in time and establishing the need for detailed studies is a mandatory step before the start of any type of ecological reconstruction.
