The purpose of this paper is to use GIS techniques for the modelling and spatial analysis of Varatec mining complex, Maramures County. The practical result of this paper, consists in the creation of the GIS database and the integration into it of maps and plans from the mining complex. A spatial analysis of a mine field is based on the effectiveness of a GIS database which will lead to 3D modelling and the representation of the topography. Among the parameters used will be slope and slope orientation or aspect because the slope determines the intensity and type of processes that model the substrate ground, and the slope orientation leads to the evolution of geomorphological processes due to climatic factors that are not evenly dispersed over the land area: solar radiation, sun exposure, precipitation and temperatures. Regarding the mining exploitation, an important element is the land use category, which was taken over by expeditious methods from the L-35-013-A-a Orthophotoplan. Another desirable aspect in this case study is the integration of the general plan from Varatec mining complex into the GIS database and spatial modelling, but also making thematic map on the main geological layers in the Varatec mining complex in order to highlight the applicability of GIS technologies in mining. The various modifications and the evaluation of the subsidence processes within the mining complex can be analysed over the years through remote sensing methods, but especially during the period when the mining complex was closed following the closure action organized by CNMPN REMIN.
