基于集对分析的矿山地质环境影响评价研究

为更好地对矿山地质环境影响进行综合评价, 针对衡山白果地区石膏矿的特点建立了评价指标体系, 并采用层次分析法确定各指标权重。将集对分析理论(SPA)用于石膏矿的地质环境影响评价中, 对12个矿山的20个开采区域进行了计算并与已有的矿山地质环境影响评估报告进行了对比分析, 发现两者对90%的被评价区域的评价结论是一致或者基本一致的, 证明了集对分析理论适合于石膏矿的评价。研究还表明, 集对分析使评价实现了定量化, 得出的结果更准确。这项研究为矿山地质环境影响评价及矿山安全管理工作提供了一条新途径。

Study on Assessment of Geological Environment Impact in Mines Based on Set Pair Analysis

In order to give a better comprehensive assessment of geological environment impact in mines, an assessment index system has been developed in view of the characteristics of gypsum mines in Hengshan Baiguo region, and the weight of each index is determined by means of analytic hierarchy process.The set pair analysis (SPA) theory was used in the assessment of geological environment impact for the gypsum mines.Comparing the calculation of 20 mining areas among 12 mines with existing assessment report for mine's geological environment impact, it is found that both are completely or nearly consistent for 90% of assessed area, indicating that set pair analysis is suitable for the assessment of gypsum mines.The research also shows that set pair analysis can make a quantitative assessment, obtaining more accurate results.It provides a new approach for assessment of geological environment and safety management in mines.
