铀矿地质勘探遗留设施环境影响的综合评价指标体系研究

Study on Comprehensive Evaluation Index System of Environmental Impact of Geological Exploration Legacy Facilities in Uranium Mine

本文选取环境污染、地质灾害、景观破坏作为识别铀矿地质勘探遗留设施环境影响的主要因素,应用层次分析法建立铀矿地质勘探遗留设施环境影响的综合评价层次结构模型,并通过判断矩阵检验模型的合理性。在此基础上,采用综合评价法评定铀矿地质矿床点对环境的影响程度,考虑其区位条件和生态恢复难易程度,确定铀矿地质矿床点环境问题的综合评价等级。评价结果可作为确定铀矿地质矿床点退役治理优先顺序的依据。

In this paper,environmental pollution,geological disasters and landscape destruction are selected as the main factors to identify the environmental impact of uranium mine geological exploration legacy facilities,and the hierarchical structure model for comprehensive evaluation of environmental impact of uranium mine geological exploration legacy facilities is established by using the analytic hierarchy process,and the rationality of the model is checked by the judgment matrix.On this basis,the comprehensive evaluation method is used to evaluate the impact of uranium mine geological deposit sites on the environment,and the comprehensive evaluation grade of environmental problems of uranium mine geological deposit sites is determined by considering their location conditions and the difficulty of ecological restoration.The evaluation results can be used as the basis for determining the priority of decommissioning treatment of uranium mine geological deposit sites.
