基于模糊综合评价法的富源县矿山开采地质环境影响评价

Geological environment impact assessment of mining of Fuyuan County based on fuzzy comprehensive evaluation method

云南省富源县矿业活动发达,矿山地质环境问题突出。本文以富源县矿山地质环境调查结果为基础,构建矿山地质环境影响评价指标体系,通过层次分析法确定各因子的权重值,采用模糊综合评价法对富源县矿山地质环境影响进行评价,划分矿山地质环境影响严重区12个、矿山地质环境影响较严重区13个、矿山地质环境影响轻微区9个。通过分析验证,评价结果与实际调查情况相符,较客观地反映了富源县矿业活动对矿山地质环境的影响,为矿山地质环境保护与恢复治理提供了依据。

In Fuyuan County,Yunnan Province,mining activities are developed and the geological environment problems of mines are prominent.Based on the survey results of mine geological environment in Fuyuan County,this paper constructs the evaluation index system of mine geological environment impact,determines the weight value of each factor through analytic hierarchy process,and adopts fuzzy comprehensive evaluation method to evaluate the impact of mine geological environment in Fuyuan County.The mining geological environment was divided into 12 areas with serious impact,13 areas with serious impact and 9 areas with slight impact.Through analysis and verification,the evaluation results are consistent with the actual investigation,which objectively reflects the impact of mining activities on the geological environment of mines in Fuyuan County,and provides a basis for the protection and restoration of the geological environment of mines.
