ABSTRACT
The paper fits in actuality treating aspects of which the apparition and evolution of the surface’s movement and deformation under due to the underground exploitation is connected. The ruin of the rocks that cover underground excavations gives birth to the subsidence phenomenon, which has a bad influence that can extent on all covering rocks’ lengths till the surface, and it manifests on a very long period of time, even after the productive activity stops. The whole mining activity produces, due to its specific, multiple and various negative effects on the environment, exemplified by: modifications on the relief, manifested in the degradation of the landscape and movements of the houses and industrial objectives in the exploitation areas; the degradation of the field through surface’s vertical and horizontal movements, provoking possible accidents and so on. In this paper I’ll present the current situation on the influence of the underground mining exploitation on the surface fields and constructions, in the conditions of the Jiu Valley mining perimeter. After the data from the measurements has been processed and after the results have been interpreted, by comparing the real submersion, resulted from the measurements, with the values of the influence factors (this has been distinguished through different diagrams, graphics and tables) I proposed and used a prognosis equation of the submersion for a point in the exploitation’s influence area. This can be applied for all points of the M.E. Livezeni tracking unit and not only. The study of the underground exploitation’s influence on the surface is necessary in order to evidence the movement phenomena and to take the measures for the protection of the surface objectives and the surface itself.
