基于层次分析和集对分析的铀矿山生态环境安全评价

Safety Evaluation of Eco-environment in Uranium Mine Based on the AHP-SPA Theory

铀矿山生态环境安全评价对于绿色矿山建设具有重要意义,为了对铀矿山生态环境安全状况进行综合评价,针对铀矿山生态环境特点,基于层次分析法和集对分析原理,建立了铀矿山生态环境安全评价模型。结合某铀矿山生态环境安全现状,开展了该铀矿山生态环境安全综合评价,计算得到综合联系度表达式并对其进行等级判断,确定了铀矿山整体生态环境安全状况等级,同时结合联系度表达式进行了分析,提出了矿山安全管理建议。结果表明:在多指标影响下具有模糊性和随机性的铀矿山生态环境安全评价问题中,该模型通过定量计算,较好的评价了铀矿山生态环境安全状况,方法简便,结果较为准确,为铀矿山生态环境安全评价提供了一个新方法。

The safety evaluation of eco-environment in uranium mine is of great significance for the green mine construction.In order to evaluate the eco-environmental safety situation in uranium mine,a model of the safety evaluation of eco-environment in uranium mine is presented,considering the eco-environmental features of uranium mine and based on the set pair analysis theory and analytic hierarchy process.According to the present situation of the ecological environment security of a uranium mine,the comprehensive evaluation of the ecological environment security of the uranium mine is carried out.The comprehensive contact degree expression is calculated,and the grade of the whole ecological environment safety status of the uranium mine is determined.At the same time,in accordance with the analysis of the contact degree expression,the mine safety management suggestions are put forward.The results show that the model is a simple and satisfied way to evaluate the eco-environmental safety situation in uranium mine,which has the fuzzy and random features and is affected by multi-index.The model provides an effective new method for the safety evaluation of eco-environment in uranium mine and it is simple with accurate result.
