Evaluation of Mining Advantages of Guangxi Bauxite Reserves Based on Multiple Indicators

Abstract

This is an essay in the field of mining engineering. Evaluation of mineral resources exploitation advantages is of great significance to improving the economic benefits of mineral resources and responding to emergencies. In this essay, taking 7 counties, including Nanning, Guigang and Laibin, Guangxi Zhuang Autonomous Region,as the research area,constructing the evaluation system of bauxite reserve mining advantages in Guangxi based on the analytic hierarchy process (AHP), five elements including transportation and power supply conditions, social economy and resource conditions, topographic conditions, land conditions and technical conditions and geological characteristics of mineral deposits and 14 evaluation factors were designed, using the spatial analysis and mining technology of GIS to calculate and evaluate the mining advantages of bauxite reserves. The evaluation results show that the mining advantage is in the range of 0.3922~4.0328, the mining advantage of Sanshui bauxite in Xiaoyi mining area of Hengxian County is the highest (4.0328), while the mining advantage of Sanli-Daling bauxite in Guigang City is the lowest (0.3922).The evaluation results are generally in good agreement with the actual situation, which proves the effectiveness of the method, and can provide an effective quantitative assessment method for evaluating the same mineral or different mineral deposits in this province or other provinces.
