Efficiency evaluation of exploitation and utilization for vanadium-titanium magnetite with DEA model in Panxi area

The evaluation of the exploitation efficiency of mineral resources is of great significance to boosting the upgrading of mining and improving the utilization level of resources.From the perspective of input and output, this paper analyzes the factors affecting the development efficiency of vanadium-titanium magnetite resources, and constructs the investment index, the ratio of technical personnel, the land area used as the input index, the total industrial output value, the total annual profit and tax, and the governance.The land area is the index system of output indicators.The mine is used as the evaluation unit.Data envelopment analysis (DEA) is used to determine the frontiers of efficiency at all levels, and the development efficiency of each vanadium-titanium magnetite mine is divided.Finally, taking the Panxi area as an example, the effectiveness of the index system and the evaluation method is verified, and the effective state and optimization direction of the mine are obtained, which provided some reference suggestions for targeted mineral development.
