江西乐安河中上游矿山环境综合评价指标体系研究

Comprehensive evaluation index system for mine environment in the uppermiddle reaches of Le'an River,Jiangxi Province

为了研究区域矿山环境综合评价指标体系,文章选择乐安河中上游为研究区,从自然地理、基础地质、矿山开发以及地质环境等要素中选取15项指标,以1.0 km×1.0 km的网格为评价单元,采用层次分析法﹣综合指数法进行综合评价。结果表明,研究区矿山地质环境影响严重区有18个单元,主要分布于铜矿、金矿等矿集区的开采区;影响较严重区有107个单元,主要分布于煤矿的开采区及铜矿、金矿等矿集区的非开采区。经野外实地验证,综合评价结果与现实情况的一致性较高,表明该评价指标体系具有一定的实用价值,可为金属矿及煤矿等区域矿山环境评价工作提供借鉴。

To study the comprehensive evaluation index system for regional mining environment,this paper took the upper-middle reaches of Le’an River as a case study and selected 15 indicators from natural geography,basic geology,mine exploitation and geological environment,and used the grid of 1.0×1.0 km as the evaluation unit.The evaluation employed analytical hierarchy process-comprehensive index method,the results of which show that there are 18 units in the most severely affected area(grade 4)in the study area,mainly distributed in the mining areas of copper and gold deposits.There are 107 units in the severely affected area(grade 3),mainly distributed in the mining areas of coal mines and the non-mining areas outside the copper and gold deposits.The field survey verified that the comprehensive evaluation results were highly consistent with the actual situation,proving a certain practical value of the evaluation index system,which can provide reference for regional mine environmental assessment on metals deposits and coal mines.
