基于多指标的广西铝土矿储备矿产地开采优势评价

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

    • 摘要: 这是一篇矿业工程领域的论文。矿产资源开采优势评价对提高矿产资源的经济效益和应对突发情况具有重要意义。本文以广西壮族自治区南宁市、贵港市、来宾市等7个县域作为研究区,基于层次分析法(AHP)构建广西铝土矿储备矿产地开采优势评价体系,设计了交通运输及供电条件、社会经济及资源状况、地形条件、土地条件和矿床开采技术条件及地质特征等5种要素14个评价因子。利用GIS的空间分析与挖掘技术,计算和评价铝土矿储备矿产地的开采优势。评价结果表明,开采优势度范围为0.3922~4.0328,横县校椅矿区三水铝土矿开采优势最高(4.0328),而贵港市三里-大岭三水铝土矿的开采优势度较低(0.3922)。评价结果与实际情况总体吻合效果好,证明了该方法的有效性,可为本省或其他省份评价相同矿种或其他矿种的储备矿产地提供一个有效的定量化评价方法。

       

      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.
