Abstract:Using GF-1 satellite images, field survey data, and ancillary materials include geographic, geologic, and meteorological data, this paper applied catastrophe theory on establishing integrated evaluation index system for mining geological environment. This evaluation system was then utilized by seven typical vanadium titano-magnetite mining areas, namely, Honge,Ma’anshan,Panjiatian, Baicao, Xiaotingjing, Yangquejing, and xiushuihe. Research results indicated that, evaluation results provided by this method corresponds to field survey records, which also shows similarity with results supported by widely applied fusion mathematic models. Compared with other methods, catastrophe theory integrated evaluation system is free from human disturbance, while abandoning assigned index weights and simplifying calculation process; thereby, it is suitable for large scale geological environment evaluation for mining area. In a nutshell, this paper provided a new integrated evaluation method for geological environment of mining areas.
