渝南地区铝土矿资源可利用性研究

    Study on the Usability of Bauxite Resources in the South of Chongqing

    • 摘要: 这一篇矿业工程领域的论文。为进一步研究渝南地区铝土矿资源的开发利用前景,本文采用实地调查法、问卷调查法、资料收集法等方法,通过构建矿产资源可利用性评价指标体系,基于层次分析及加权叠加法的评价模型对渝南地区铝土矿资源的可利用性进行深入研究和评价。首先根据专家打分结果,选择平均得分排名前12的指标作为本次评价指标,其次采用层次分析法确定12个评价指标的权重,最后运用加权叠加法确定各矿区的评价指数。评价指数得分数值越高,铝土矿资源的可利用性越高。渝南地区15个铝土矿区中无易利用矿区,可利用矿区4个,近期难利用矿区7个,难利用矿区4个。利用层次分析法和加强叠加法所建立的评价模型可为铝土矿资源的可利用性评价提供科学参考。

       

      Abstract: This an article in the field of mining engineering. In order to further study the development and utilization prospects of bauxite resources in the southern region of Chongqing, this article adopts methods such as on-site investigation, questionnaire survey, and data collection. By constructing an evaluation index system for the availability of mineral resources, an evaluation model based on Analytic Hierarchy Process and Weighted Superposition Method is used to conduct in-depth research and evaluation of the availability of bauxite resources in the southern region of Chongqing. Firstly, based on the expert scoring results, select the top 12 indicators with average scores as the evaluation indicators for this evaluation. Secondly, use the Analytic Hierarchy Process to determine the weights of the 12 evaluation indicators. Finally, use the weighted superposition method to determine the evaluation indicators for each mining area. The higher the score of the evaluation index, the higher the availability of bauxite resources. Among the 15 bauxite mining areas in the southern region of Chongqing, there are no easy to use mining areas, but there are 4 available mining areas. Recently, there are 7 difficult to use mining areas, and 4 difficult to use mining areas. The evaluation model established using Analytic Hierarchy Process and Enhanced Superposition Method can provide scientific reference for the evaluation of the availability of bauxite resources.
