Abstract: Nowadays，“3S” technology has become one of the most favorable means to study the surface resources Based on “3S” technology，with the use of the remote sensing date extracted from high-resolution IKONOS images and other data，the remote sensing，geological，geographic and meteorological data were obtained By adopting the With the information provided by the data in Panxi rift valley metallegenic belt，the mine geo-environment assessment model is built with the analytic hierarchy process to evaluate the mine geo-environment of the studied area The evaluation results indicate that the overall mine geo-environmental quality in study area is unsatisfactory:①Mining activities damage the landscape seriously，and occupy a large amount of land and having no ecological restoration after the exploitation of mineral resources②Mining activities lead to many large-scale geologic hazards and a number of hidden dangers③There are many copper tailing，iron tailing，lead-zinc tailing and other mine tailings in study area，which easily results in surface water pollution once washed by rain.

Key words: 3S technology, Mine geo-environment assessment, Vanadium-titanium magnetite
