矿山地质环境影响评价是一个兼具复杂性和模糊性的系统,是将有限的修复资源如何合理地分配到不同影响程度矿山的科学依据.为了更精准、更高效地评价矿山对周边地质环境的影响状况及程度,本文选择南宁市武鸣区38个灰岩矿山为研究对象,从地质环境背景、资源破坏、地质灾害、矿山开发利用状况 4个方面选取了 14个评价指标构建矿山地质环境影响评价体系,采用模糊层次分析法和熵值法相结合(FAHP-Entropy组合)赋权法综合评价矿山地质环境影响程度,并基于MATLAB平台开发了矿山地质环境影响评价系统(MGES),对38座灰岩矿山进行评价.评价结果显示,对地质环境影响较轻的矿山仅占比 21%,对地质环境影响较严重的矿山占比 47%,对地质环境影响严重的矿山占比 32%,武鸣区矿山地质环境影响程度整体属较严重~严重级别.研究结果为武鸣区政府有限的治理资金指明了优先治理方向.该系统操作简单,可以弥补传统方法复杂、难操作的不足之处,对于处理大规模数据有极大优势,可为同业技术人员和学者开展矿山地质环境影响评价工作提供借鉴.
Mine geological environmental impact evaluation based on FAHP-Entropy Weighting Method:an example of limestone mines in Wuming District
Mine geological environmental impact evaluation is a system characterized by complexity and fuzziness,which provides a scientific basis for the rational allocation of limited restoration resources to mines with different degrees of impact.In order to evaluate the impact and extent of numerous mines on the surrounding geological environment more accurately and efficiently,this paper selects 38 limestone mines in Wuming District,Nanning City as the research objects.Fourteen evaluation indicators,encompassing geological environmental background,resource disruption,geological hazards,and the condition of mining development utilization,have been chosen to construct the evaluation framework for the mine geological environment.The FAHP-Entropy combination weighting method,which combines fuzzy analytic hierarchy process(FAHP)and entropy method,is used to comprehensively evaluate the degree of geological environmental impact of the mines.A mining geological environmental impact evaluation system(MGES)is developed based on the MATLAB platform.Among the MGES application examples,38 limestone mines have been evaluated,revealing that only 21%of the mines have a minor impact on the geological environment,while the percentage rises to 47%for mines with a moderate impact and 32%for mines with a severe impact.The overall evaluation of the geological environmental impact in Wuming District falls within the severe to critical level,which provided guidance for the limited governance funds of the Wuming District government to prioritize the management of mining areas.The system is easy to operate and can compensate for the complexity and difficulty of traditional methods.It has great advantages in dealing with large-scale data and can serve as a reference for professionals and scholars in the field of mining geological environmental impact evaluation.
